Wireless Display System 1 This symbol points out potential fire hazard. This symbol points out potential electrical shock hazard.Study these SAFETY RULES carefully before install-ing, operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The generator can operate safely, efficiently and reli-ably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warn-ings in this manual, and on tags and decals affixed to the unit are, therefore, not all inclusive. If using a procedure, work method or operating technique that the manufacturer does not specifically recommend, ensure that it is safe for all personnel. Also make sure the procedure, work method or operating technique utilized does not render the generator unsafe.DANGER Despite the safe design of this generator, operating this equipment imprudently, neglect-ing its maintenance or being careless can cause possible injury or death. Permit only responsible and capable persons to install, operate or main-tain this equipment. Potentially lethal voltages are generated by these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator. Parts of the generator are rotating and/or hot during operation. Exercise care near running generators.  GENERAL HAZARDS For safety reasons, the manufacuter recommends that this equipment be installed, serviced and repaired by an Authorized Service Dealer or other competent, qualified electrician or installation tech-nician who is familiar with applicable codes, stan-dards and regulations. The operator also must com-ply with all such codes, standards and regulations.Installation, operation, servicing and repair of this (and related) equipment must always comply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electri-cal and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, ensure that the generator is installed, operated and serviced in accordance with the manufacturer’s instructions and recommendations. Following installation, do nothing that might render the unit unsafe or in noncompliance with the aforementioned codes, standards, laws and regulations.The engine exhaust fumes contain carbon monox-ide gas, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. For that reason, adequate ventilation must be provided. Exhaust gases must be piped safely away from any building or enclosure that houses the generator to an area where people, animals, etc., will not be harmed. This exhaust system must be installed properly, in strict compliance with applicable codes and standards.Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.Adequate, unobstructed flow of cooling and venti-lating air is critical in any room or building hous-ing the generator to prevent buildup of explosive gases and to ensure correct generator operation. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can seri-ously affect safe operation of the generator.Keep the area around the generator clean and uncluttered. Remove any materials that could become hazardous.When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.•••••••The engine exhaust from this productcontains chemicals known to the stateof California to cause cancer, birth defects or other reproductive harm.•WARNING:•This product contains or emits chemicalsknown to the state of California to causecancer, birth defects or other reproductive harm.•WARNING:• SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas. Safety should be stressed to all operators, potential operators, and service and repair technicians for this equipment. SAVE THESE INSTRUCTIONS – This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. 
2 Wireless Display SystemInspect the generator regularly, and promptly repair or replace all worn, damaged or defective parts using only factory-approved parts.Before performing any maintenance on the gen-erator, disconnect its battery cables to prevent accidental start-up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–) first. Reconnect that cable last.Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating con-ditions from leaking exhaust gases, fuel leakage, oil leakage, etc. ELECTRICAL HAZARDS All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages to the transfer switch, as does the standby generator. Avoid contact with bare wires, terminals, connections, etc., on the gen-erator as well as the transfer switch, if applicable. Ensure all appropriate covers, guards and barriers are in place before operating the generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce shock hazard.Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.If people must stand on metal or concrete while installing, operating, servicing, adjusting or repair-ing this equipment, place insulative mats over a dry wooden platform. Work on the equipment only while standing on such insulative mats.The National Electrical Code (NEC), Article 250 requires the frame and external electrically con-ductive parts of the generator to be connected to an approved earth ground and/or grounding rods. This grounding will help prevent dangerous electri-cal shock that might be caused by a ground fault condition in the generator set or by static electric-ity. Never disconnect the ground wire.Wire gauge sizes of electrical wiring, cables and cord sets must be adequate to handle the maxi-mum electrical current (ampacity) to which they will be subjected.Before installing or servicing this (and related) equipment, make sure that all power voltage supplies are positively turned off at their source. Failure to do so will result in hazardous and pos-sibly fatal electrical shock.Connecting this unit to an electrical system nor-mally supplied by an electric utility shall be by means of a transfer switch so as to isolate the generator electric system from the electric utility distribution system when the generator is operat-ing. Failure to isolate the two electric system power sources from each other by such means, will result in damage to the generator and may also result in injury or death to utility power workers due to backfeed of electrical energy.••••••••••Generators installed with an automatic transfer switch will crank and start automatically when normal (UTILITY) source voltage is removed or is below an acceptable preset level. To prevent such automatic start-up and possible injury to person-nel, disable the generator’s automatic start circuit (battery cables, etc.) before working on or around the unit. Then, place a “Do Not Operate” tag on the generator control panel and on the transfer switch.In case of accident caused by electric shock, imme-diately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting imple-ment, such as a dry rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.Never wear jewelry when working on this equip-ment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving com-ponents causing injury. FIRE HAZARDS Keep a fire extinguisher near the generator at all times. Do NOT use any carbon tetra-chloride type extinguisher. Its fumes are toxic, and the liquid can deteriorate wiring insulation. Keep the extin-guisher properly charged and be familiar with its use. If there are any questions pertaining to fire extinguishers, consult the local fire department. EXPLOSION HAZARDS Properly ventilate any room or building housing the generator to prevent build-up of explosive gas.Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no com-bustible materials are left in the generator com-partment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround-ing the generator clean and free from debris.These generator sets may operate using one of several types of fuels. All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with care. Comply with all laws regulat-ing the storage and handling of fuels. Inspect the unit’s fuel system frequently and correct any leaks immediately. Fuel supply lines must be prop-erly installed, purged and leak tested according to applicable fuel-gas codes before placing this equip-ment into service.Diesel fuels are highly FLAMMABLE. Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. Natural gas is lighter than air, and LP gas is heavier than air; install leak detectors accordingly.••••••••
3OPERATION AND MAINTENANCEThe operator is responsible for proper and safe use of the equipment. The manufacturer strongly recom-mends that the operator read this Owner's Manual and thoroughly understand all instructions before using this equipment. The manufacturer also strong-ly recommends instructing other users to properly start and operate the unit. This prepares them if they need to operate the equipment in an emergency.It is the operator's responsibility to perform all safety checks, to make sure that all maintenance for safe operation is performed promptly, and to have the equipment checked periodically by an Authorized Service Dealer. Normal maintenance service and replacement of parts are the responsibility of the owner/operator and, as such, are not considered defects in materials or workmanship within the terms of the warranty. Individual operating habits and usage contribute to the need for maintenance service.Proper maintenance and care of the generator ensures a minimum number of problems and keeps operating expenses at a minimum. See an Authorized Service Dealer for service aids and accessories.Operating instructions presented in this manual assume that the standby electric system has been installed by an Authorized Service Dealer or other competent, qualified contractor. Installation of this equipment is not a “do-it-yourself” project.HOW TO OBTAIN SERVICEWhen the generator requires servicing or repairs, contact an Authorized Service Dealer for assistance. Service technicians are factory-trained and are capa-ble of handling all service needs.When contacting an Authorized Service Dealer about parts and service, always supply the complete model number of the unit as given on the front cover of this manual or on the DATA LABEL affixed to the unit.INTRODUCTIONThe wireless display system consists of two identical radio transceivers, one mounted near the generator and the other (the one with the display), should be in a convenient viewing location. The system has a “line of sight” range of about 300 feet but this will be reduced if the signal has to go through walls, etc.. The display is intended to show the status of the genera-tor and warn you if the system is in an alarm state. It also provides the following additional functions:Permanent time/date stamped history of generator events such as starting and stoppingAllowing remote starting and stopping of the gen-erator••Facility to set an exercise time & day from the dis-playFacility to adjust the “bad” utility voltage thresh-oldFacility to set up a service scheduleAbility to add extra displaysGraphing capabilityThe unit can be either battery powered or fed from a separate plug in wall transformer. The History is kept in permanent memory that is not lost even when all power is lost. The clock function is kept alive by a separate, replaceable 10 year life battery.BATTERY OPERATIONThe wireless display can be operated either from a plug in wall transformer or from three AAA alkaline batteries. The batteries can be rechargeable but are NOT recharged from the wall transformer and should be separately charged. In the case of battery opera-tion, the unit will go to sleep for 60 seconds then exchange data for up to two (2) seconds to conserve battery life. The display screen will turn off in the sleep mode unless there is an alarm to be displayed. It can be awoken by pressing the ENTER key after which it will remain awake for one (1) minute if no further keys are pressed. If the display is operated continuously on batteries, the expected battery life is three (3) months when using standard alkaline 1.2Ah batteries. The batteries are NOT used to retain data such as the history log or the radio settings, they will not be lost in the event of a dead battery.NOTE 1:In battery sleep mode it will take up to two (2) minutes to detect if the radio link is lost. This long delay is to allow for the unit’s sleep time.NOTE 2:In battery sleep mode, if the wall transformer is plugged into the unit, it will take up to one minute to recognize this fact. There is a separate battery for the time and date function. This has an expected life of ten years after which it can be replaced. To replace the bat-tery, remove the four screws holding on the back of the case and carefully fold out the circuit board without disconnecting the display. Remove the large yellow battery module from the centre of the board by pulling on the corners. Replace the battery THE CORRECT WAY ROUND with the spot in the corner of the battery facing the on/off switch. Replace the cir-cuit board and the back of the case. You will need to reset the time and date. The GENERAC part number for the battery is 0A7287G.•••••Wireless Display System
4 INSTALLATIONFor easier installation, the batteries should first be fitted into the display unit (Figure 1). This will allow you to walk around and find the best location for the unit while still receiving good signal strength. Attach the other transceiver to the generator and mount it as high as possible, preferably away from any structures to get a maximum signal.Figure 1 — Open Display Unit1. Insert the batteries (Figure 2).Figure 2 — Insert Batteries2. Connect the generator end transceiver and ensure it is turned on.3. IMMEDIATELY turn on the display, one minute will pass while the generator tries to find it’s dis-play.4. The display will show that it is searching for the generator and the yellow LED may flash occasion-ally as it receives data from the generator trans-ceiver. This is due to the unit searching for the correct channel.5. Once the generator is found, the radio link is now setup and the settings will be remembered next time the display unit is turned on. If the genera-tor is not found, an error message will briefly be shown, and the yellow LED will flash at one (1) second intervals to indicate the display unit was unable to find the generator.6. If the battery power to the generator (and there-fore the end transceiver) is ever disconnected, the radio link will need to be reset. See the section titled “Reset Radio”.7. If the generator is not talking to it’s transceiver, but the radios are talking to each other, this will be indicated by an appropriate alarm which will be displayed after a 30 second period. Check the wiring and connection to the generator.8. Place the display at the preferred location. Do not permanently mount it yet.9. Plug the wall transformer into the display so as not to use up the batteries. Familiarize personnel with the radio menu (by reading the manual in conjunction with operating the display).10. Navigate the display to show the “Radio Information” screen from the radio menu.11. Monitor the signal strength and relocate the dis-play if the signal strength is poor or non existent. The signal strength display is only updated if the unit can communicate, (which occurs every two (2) seconds), and will be set to display zero if the unit cannot communicate within a ten (10) sec-ond period.12. Mount the display using the holes on the back to hang onto two suitably sized fixing screws in the drywall 2¼ inches apart. It should be vertically mounted on a wall BETWEEN studs for maxi-mum signal strength (Figure 3).Figure 3 — Mounting HolesWireless Display System
5Wireless Display System13. Set the time and date into the clock, use the instructions given in the "Time and Date Menu" section. The time & date will be remembered even if the battery goes dead. There is a separate, replaceable 10 year battery for this function.14. The communications LED will light solid to show data is being received. A flashing LED indicates the unit was unable to find the generator.15. Set an exercise day and time now (see "Exercise Menu" section).THE COMMUNICATIONS LEDThe communications LED will light solid to show data is being received. If the LED flashes at regular one (1) second intervals, it indicates the unit was unable to find the generator. Irregular flashing is an indication of poor reception.GENERATOR COMMUNICATIONSThe transceiver requests data from the generator every two (2) seconds and this is stored inside the transceiver locally. The data is relayed to the base station over the radio link every time it is requested by the display about every two (2) seconds. When on battery power, the data is only requested every minute to conserve batteries. If the generator is not talking to it’s transceiver, but the radios are talking to each other, this will be indicated by an appropri-ate alarm which will be displayed after a seven (7) second period (Figure 4). Check the wiring and con-nection to the generator.Figure 4 — Sample AlarmWARNINGRADIO OKBUT GENIS NOTTALKINGTHE DISPLAYCONTRAST ADJUSTMENTThe display contrast can be adjusted from the “Settings” menu. Any changes to the contrast setting will be remembered even if power is removed from the display.BACKLIGHTThe display is backlit providing that it is powered from the wall transformer. If batteries are being used the backlight is disabled to conserve power. The backlight is lit whenever a key is pressed. It will remain lit for 20 seconds if there are no further key-presses. If an alarm occurs, the backlight will flash at a one (1) second rate (not if battery powered).BUTTONSOperation of the display is controlled by three (3) buttons labeled +, —, and Enter. These buttons are used to navigate the display to the required page, or to enter data. The +/— buttons are also referred to as the arrow keys. Holding down a button for more than half a second will cause it to autorepeat until it is released.BATTERY AND SIGNAL STRENGTH INDICATORSIn the top left corner of the display, there are two icons (or pictures) that give a quick indication of the state of the internal battery and the radio signal strength (Figure 5). The battery is represented by the left hand, single tall rectangle which is drawn as being somewhere between full and empty. Full represents greater than 75% capacity, mostly full represents 50-75% capacity, half full represent 25-50% and mostly empty represents 0-25% capacity. The signal strength icon is shown to the right of the battery icon as three vertical bars representing greater than 25%, greater than 50%, and greater than 75%. Three bars indicate excellent signal strength, two bars represent good signal strength (about 45%), one bar represents weak signal strength. Two bars is the normal indication.Figure 5 — Battery & Signal StrengthSignalStrengthIs ExcellentBatteryhas morethan 75%CapacityBatteryhas 50-75%CapacityBatteryhas 25-50%CapacityBatteryhas lessthan 25%CapacitySignalStrengthIs GoodSignalStrengthIs WeakNoSignal
6 ALARM AND STATUS DISPLAYThe display will normally show the operating status of the generator or an alarm message if one is pres-ent. See Figures 6 and 7.Figure 6 — Sample Alarm ScreenWARNINGLOWBATTERYALARMFigure 7 — Sample Status ScreenT+RUNNINGAND COOLINGDOWNWhen a key is pressed, the display switches into menu mode which will allow access to the special functions of the unit. If no keys are pressed for 30 seconds, the unit will revert back to the status or alarm display.When an alarm occurs, the display will show a flash-ing alarm icon and the alarm message. The backlight will also flash if not in battery mode. If the alarm goes away, the display will revert to the status display. If two or more alarms exist, the most recent one to occur will be displayed. If a key is pressed to go into menu mode, when returning to the alarm display, the latest alarm will be displayed.THE MENU SYSTEMPressing any key will switch the display into menu mode (Figure 8). If no further keys are pressed for one minute, the unit will revert back to the status display. Menu Mode is indicated by a menu name on the right side of the display, and an icon (picture) on the left side. Use the up/down arrow keys to move to the menu required, then press the enter key to see the choices.Figure 8 — Menu SystemT+STATUS DISPLAYTEST MENULOGHISTORY MENUEMAILALARMS EMAIL MENUSETTINGS MENUEXERCISE MENURADIO MENUTimeTIME &DATE MENUtGRAPH MENUOnce a menu is selected, there will be a list of choic-es. The current choice is shown by a rectangle drawn around it (Figure 9). Use the arrow keys to navigate the rectangle to the topic required, then press the enter key.Figure 9 — Menu ChoicesChoice 1Choice 3Choice 2Use ArrowKeys to Movethe SelectorSTATUS MENUT+The status menu item simply provides a way to show the current status message coming from the generator. This is shown as a text message on the LEFT hand side of the display. Normally this will show the following message: “READY TO RUN”.TEST MENUThe test menu permits starting and stopping the generator. Use the arrow keys to navigate to the appropriate option. If choosing to start the generator, the two arrow keys will need to be pressed together to confirm the command. To cancel the command, press the enter key.Wireless Display System
7If the generator can run at a low speed (Quiet Test QT), this option is available. If there is an automatic transfer switch, there is the option to run the genera-tor and transfer onto generator power. Once the gen-erator is started or stopped, the state of the generator will be shown by a “*” symbol next to the command issued. For example:Normal Start* You started the generator at normal speed.Start & transfer* You started the generator & transferred to generator powerLow speed start* You started the generator at low speed (Quiet Test)Stop generator* You stopped the generatorThere is a one minute cooldown time after you stop the generator, so it will continue to operate for one minute after the stop command is issued. In the event that the stop command fails (such as if you take the display out of range, you can either retry the stop command or manually stop the generator by switch-ing it to the “off” position.HISTORY MENULOGThe history log is a chronological list of “events” that have occurred to the generator. An event is any change in status such as an alarm, a start or stop, the keyswitch being operated, etc.. These events are permanently stored inside the display module along with a time and date stamp when they occurred. They will not be lost even if the battery goes dead, but there is the option to erase the log.When entering the history menu, the most recently logged event (Event 1) will be displayed. The actual event will be shown as a message on the left hand portion of the screen (Figure 10). The time and date of the event will be shown on the right hand part of the screen, and the event number displayed on the underlined title bar. By using the arrow keys, navigate through the events which are stored in chronological order. Event 1 is the most recent and event 100 is the oldest. The events are stored in a circular fashion so it's possible to scroll from Event 1 back to event 100 by using the “UP” arrow key. The history log can be cleared from the “SETTINGS” menu.Figure 10 — History MenuHIGHCOOLANTTEMP.EVENT 7TIME10:11:12DATE02/02/02Event NumberTime & Date of the EventEventTypeEMAIL MENUEMAILALARMSCurrently this menu has no function.SETTINGS MENUThe following list of options will be presented:Adjust ContrastAC ThresholdService ScheduleClear HistoryAdd me to network.ADJUST CONTRASTThe display contrast can be adjusted using the two arrow keys. Once the desired contrast level is reached, press the enter key to store it.VAC THRESHOLDAdjust the AC voltage level used by the generator to determine if the utility is bad. If the utility voltage falls below this level, the generator will start. Note that if the generator battery is ever disconnected or goes dead, this setting will need to be re-entered. The range of adjustment is limited by the generator (for example – a maximum of 170 VAC on air-cooled units) even though the display allows a larger range. This is to accommodate different models.SERVICE SCHEDULEThe display can be set to alarm on a specific date for an alert that a service is required. The date is set using the two arrow keys. Setting the month to zero disables this whole function. When the alarm occurs, it can be cancelled by re-setting the service date only.•••••Wireless Display System
8 EXERCISE MENUNormally the exercise time is set on the gen-erator control board as it powers up. If an exercise time has not been set on the control board, all it’s LED’s will flash and an alarm will be set on the wireless display – “EXERCISE TIME NOT SET”.The exercise page of the wireless display can be used to overwrite any exercise time set in the generator. Use the arrow keys and follow the on-screen instruc-tions to set the time and day. The wireless display cal-culates the difference in time from the exercise date and time to the current date and time, and down-loads this to the generator. This means you MUST set the correct date and time on the display. The exercise cycle is repeated at the same time weekly and does not use the wireless system to do this, all the timing is in the generator. If you ever remove power from the generator, you will need to re-set the exercise time when you re-set the radio (see the reset radio com-mand in the radio menu section).RADIO MENUThe following list of options will be presented:Radio informationChange ChannelReset RadioAdd New DisplayTest Radio LinkRADIO INFORMATIONThis selection shows statistics about the radio link. There are displays of signal strength and signal qual-ity as percentages, as well as an indication of the current system channel. For ease of use, the display will NOT revert to the status/alarm screen after one minute if no keys are pressed.If the signal strength is poor, re-locate the display to somewhere with a higher signal strength. Unplug the wall adapter and walk around while observing the signal strength. Mount the unit at a point where the signal strength is at a high level (not necessarily the highest level). The transceiver at the generator end can then be relocated. The best position for this is as high up as possible away from any structures.If the signal quality is low but the signal strength is good, there may be some interference. See the section on "Changing Channels".•••••CHANGING CHANNELSChannel selection is normally automatic, manually changing channels should only need to be done if experiencing interference from other equipment. This can be identified by looking at the signal strength and the signal quality. If the signal strength is good but the quality is not, there may be some interference. Changing channels on the main display will auto-matically change the channel on the generator end provided a link has been established. If the “change channel” message fails for any reason, the units will revert to their old channel selection. A new channel setting will be remembered for the next time the unit is powered up. To change channels on an established and working link, simply select “Change Channel” from the Radio menu, then enter a new channel number.Changing the channel number on a link that is not established is a little more complex, the only reason this may need to be done is if a link cannot be estab-lish because the default channel is noisy. To perform this task, follow these instructions:1. Remove power from the generator end of the link. Power up the display.2. Go to the radio menu and select “Reset radio”. This will try and establish a link but it will fail, the process will take about one minute.3. Go to the “Change Channel” menu and select a new channel.4. Go back and select the “Reset Radio” command and immediately turn on the generator end of the link. 5. The radio link should establish itself on the chan-nel selected. This will be remembered even when the power is turned off to the display.If the unit is a secondary display, no checking is done to ensure the channel matches the current system channel. Set the channel to the current system chan-nel. Look on the main display and select the radio menu, then select “Radio Information”. This will tell you the current channel that is being used.RESET RADIONormally the system will set itself up out of the box, however if you have to replace either of the transceiv-ers ( the display or the generator end), or if power is ever lost to the generator end (such as a flat genera-tor battery) you will need to re-train the system and re-set the exercise time. You will NOT have to re-train the system if the battery in the display goes flat, the system will remember the radio settings.If communications are totally lost for an unexplained reason, you may want to perform a new radio setup.1. Carry the display to a point near the generator and turn it on. Go to the radio menu.Wireless Display System
92. Disconnect the transceiver at the generator end, then reconnect it. You now have one (1) minute to complete the setup process.3. On the display select “Reset Radio”. The display will show it is searching for the generator, this process will last one minute and a countdown timer will be displayed.4. Once the time is up a message will be displayed showing that the generator has been found. The radio settings will be remembered for the next time.5. Re-set the exercise time.ADD NEW DISPLAYA second (third or fourth) display can be added to the network. Each display needs to be trained as to what it’s network consists of. This is the function of the “Add New Display” selection.1. Locate the new display near the main display and turn it on.2. On the NEW display, go to the “Settings” menu and select “Add me to Network”.3. Choose a unique address for the additional dis-play, for example one that does not conflict with any other additional displays. If there are only two displays, then any number (other than zero), will do. Zero is used to cancel the command.4. On the MAIN display go to the radio menu and select “Add New Display”. Press enter on both displays. A countdown timer will be displayed as the two units re-train.5. At the end of the period, the new display will show that the training was successful.TEST RADIO LINKThis feature allows the “basic” data integrity of the link to be tested, it may not be necessary to use this feature. For ease of use, the display will NOT revert to the status/alarm screen after one minute if no keys are pressed. Test data is sent over the link to the generator end, and then sent back from the generator end to the display. The data received is displayed on the bottom line of the display. Good data is shown as a series of forward slashes (//////). Timeouts on the link are dis-played as the “#” character and corrupted data reply messages are shown as the “@” character. The mes-sages are termed “basic” because they are not error checked or corrected.Radio information such as signal strength, channel number and quality is also shown alongside the test data.TIME & DATE MENUTimeThere is a display of the current time, day, and date shown on the menu icon page. Only the time display will update, the date display is just a snapshot of the current date (Figure 11).Figure 11 — Time & Date MenuMENUTIMEANDDATE04/17/07Monday15:25:03TimeSelecting this menu permits setting the clock to the correct time, day and date. This will only need to be done the first time they system is powered up, or to correct any small errors in the time. Use the two arrow keys to set the correct time, day and date.GRAPH MENUtThe Graph menu permits graphing data in real time on a rolling screen (Figure 12).
