ABGHICFDEJDAB CEFig.2Fig.3Fig.4Fig.5To start an automatic scan on all channels, press and hold [CH] for two seconds.The main unit will scan from one channel to another and back. The reading forindividual channel will be displayed for five seconds. Press any key to end theautomatic scan.MAXIMUM AND MINIMUM TEMPERATURESThe maximum and minimum recorded indoor temperatures and those of eachchannel will be automatically stored in memory.To display them,1. Press [CH] to locate the desired channel.2. Press [MAX/MIN] repeatedly to display the current, maximum (MAX)and minimum (MIN) temperatures. The readings of the indoortemperatures will also be displayed.To clear the memory of a particular channel,1. Press [CH] to locate the desired channel.2. Press [CLEAR]. Note it will also erase the memory for the indoortemperatures. If you press [MAX/MIN] now, the maximum and minimumtemperatures will have the same values as the current ones until differentreadings are recorded.ICE WARNING FUNCTIONThe GE5805WS4 includes an ice warning function. This feature is built intoremote sensor CHANNEL 1 functions.When the temperature recorded at CHANNEL 1 falls to between -2°C (28.4°F)to +3°C (37.4°F) the current outdoor temperature will flash.TO DEACTIVATE THIS FUNCTION, SET THE REMOTE SENSOR TOCHANNEL 2 or CHANNEL 3.DISCONNECTED SIGNALSIf without obvious reasons the display for a particular channel goes blank,press [CH] and [MAX/MIN] to enforce an immediate search. If that fails,check if the remote unit of that channel is still in place. Make sure thetransmission is within range and path is clear of obstacles and interference. Noreading will be shown if no remote unit is assigned to that channel.LOW BATTERY WARNINGWhen it is time to replace batteries, the respective low-battery indicator willshow up when the respective channel is selected. The battery level of the mainunit will be shown on the indoor temperature when it is running low.HOW TO USE THE TABLE STAND OR WALLMOUNTING (Fig. 5)Flip the table stand out to place the main unit on a flat surface. Or you can hidethe stand and mount the unit on a wall using the recessed hole.As for the remote unit, mount the unit on a wall using the recessed hole.THE RESET BUTTONThe [RESET] button is used to enhance synchronization of signals after batteryreplacement or when the unit is operating in an unfavorable way ormalfunctioning. Use a blunt stylus to hold down the button. All settings willreturn to their default values.MAINTENANCEWhen handled properly, this unit is engineered to give you years of satisfactoryservice.

BATTERY COMPARTMENTAccommodates two (2) UM-3 or “AA” size 1.5V batteriesE. BATTERY DOORHINTS FOR BEST OPERATION• Assign different channels to different remote units.• Insert batteries for remote units before doing so for the main unit.• Set the main and remote units within range (20 to 30 meters).• Try different set-ups for best transmission and reception.• Position the remote units away from direct sunlight, rain or snow.BATTERY AND CHANNEL INSTALLATION:REMOTE UNIT (Fig. 3)1. Remove the screws on the battery compartment.2. Select the channel number on the CHANNEL slide switch.3. Install 2 batteries (UM-3 or “AA” size 1.5V) strictly according to thepolarities shown.4. Replace the battery compartment door and secure its screws.Note that once a channel is assigned to a remote unit, you can only change it byremoving the batteries or resetting the unit.BATTERY INSTALLATION: MAIN UNIT (Fig. 4)1. Open the battery compartment door.2. Insert two (2) UM-3 or “AA” size 1.5V batteries.3. Press RESET.4. Replace the battery compartment door.GETTING STARTEDOnce batteries are in place for the remote units, they will start transmittingsampling roughly at 30-second intervals.The main unit will also start receiving once batteries are installed. Thetemperature of the selected channel will be displayed on the main display andthe indoor temperature on the secondary display. The main unit willautomatically update its readings at 30-second intervals.If no signals are received, blanks will be displayed. Press [CH] and [MAX/MIN] simultaneously to enforce an immediate search. This is useful insynchronizing the transmission and reception of the remote and main units.INDOOR AND OUTDOOR TEMPERATURESThe indoor temperature is shown on the secondary display.As for the remote sites or channels, press [CH] repeatedly to go from onechannel to another. The kinetic wave display on the channel number indicatesthe reception of that particular channel is in good order.Fig.1MULTI-CHANNEL CABLE FREEIN-OUT THERMOMTERMODEL: GE5805WS4USER'S MANUALSPECIFICATIONSTemperature MeasurementMain unitIndoor Temperature measurementProposed operating range : -5.0°C to +50.0°C (23.0°F to 122.0°F)Temperature resolution : 0.1°C (0.2°F)Temperature Display in °C or °FRemote unit Proposed operating range : -20.0°C to +60.0°C (-4.0°F to 140.0°F)Temperature resolution : 0.1°C (0.2°F)RF Transmission Frequency : 433 MHzNo. of Remote unit : Maximum of 3RF Transmission Range : 30 meters (open area)Temperature sensing cycle : around 30 secondsPowerMain unit : use 2 pcs UM-3 or ”AA” 1.5V batteryRemote sensing unit : use 2 pcs UM-3 or “AA” 1.5V batteryWeightMain unit : TBC g (without battery)Remote sensing unit : TBC g (without battery)DimensionMain unit : 66.5 x 74 x 30 mm (L x W x T)Remote sensing unit : 80 x 70 x 33.5 mm (L x W x T)NOTE ON COMPLIANCEThis device complies with Part 15 of the FCC Rules.
