5About the RNS® System Indications for Use The RNS® System is an adjunctive therapy in reducing the frequency of seizures in individuals 18 years of age or older with partial onset seizures from no more than two foci that are refractory to two or more anti-epileptic medications. Purpose of your Remote Monitor The NeuroPace® Remote Monitor Model DTR-300 is designed for use with the RNS® Neurostimulator Model RNS-300M. A Remote Monitor lets you collect data from the Neurostimulator, and send the data to your doctor. The Remote Monitor consists of a special software program installed on a laptop computer, a Wand and telephone accessories. After connecting the hand-held Wand to the laptop, data in the Neurostimulator are collected by placing the Wand over the Neurostimulator. The Wand uses Radio Frequency (RF) communication to collect the data. Data are stored in the laptop and then sent to a secure database over a phone line. The database is called PDMS (Patient Data Management System) and only your doctor can access your data. Your doctor will review the data and use the results to adjust the Neurostimulator settings during future office visits. Important Information Please see your RNS® System Patient Manual for important safety information such as Contraindications, Warnings, and Precautions and additional information regarding the RNS® System and your therapy. You must be willing to collect data daily from the Neurostimulator, and then send the data to the PDMS database at least once a week. Your doctor may direct you to collect and send data more often.
The Remote Monitor and its Parts The Remote Monitor Software on Laptop Computer The Remote Monitor software program is already installed on the laptop computer. It stores data collected by the Wand, and then sends it to the secure PDMS database over a phone line. (The laptop computer you receive may not be the same model shown here. The location of power cord, phone cord and USB connections may also differ from the model shown here.) Wand The Wand collects data from the Neurostimulator and stores it in the laptop computer. Data are collected through Radio Frequency (RF) communication. Power cord The power cord powers the laptop computer and charges its battery. The laptop comes with battery installed, but not fully charged. 6
(The Power Cord may come as 1 or 2 pieces, depending on the laptop computer model you receive.) Phone Accessories The phone accessories let you connect the laptop computer to your phone wall jack. A phone cord is included along with a Phone Splitter that converts 1 phone wall jack into 2 separate jacks. Quick Start Guide The Quick Start Guide is short reference guide that covers the key tasks for operating the Remote Monitor. Carrying Case The carrying case is for storing your Remote Monitor parts when not in use. Make sure you have all the items described above.

CAUTION: • DO NOT use (position) the Wand over any other medical device. The Wand may momentarily interfere with operation of the other device but should not result in any harmful effects. This includes other implanted devices such as a pacemaker or defibrillator, as well as devices that are used outside the body, such as a CPAP machine. Not following these instructions may momentarily interfere with the operation of other medical devices.
9• DO NOT use the laptop for any other purpose except as instructed in this Manual. The laptop is designed to operate only as part of the Remote Monitor. DO NOT make any changes or adjustments to the laptop hardware or software. This includes attaching external devices like a mouse, or inserting CDs or DVDs into the drive. Any changes you make that are not part of the instructions in this Manual may damage the Remote Monitor and may not allow you to send data to the PDMS database. • You should collect data daily from the Neurostimulator, and send it to the PDMS database at least once a week. Your doctor may direct you to collect and send data more often. By sending your data on a regular basis, your doctor will be able to identify problems and make adjustments. Your doctor will also be able to determine when battery power is getting low. If you do not collect and send data as directed, your doctor may not be able to review your data and make adjustments on a timely basis. If you are having seizures more frequently or with greater severity, talk with your doctor as soon as possible. Your doctor may ask you to collect and send data to the PDMS database on a more frequent basis until adjustments can be made to the Neurostimulator settings. There may be a few times when you will be unable to collect and send data. This might be due to a damaged Wand or laptop, a problem with the phone line, or while you are travelling. Talk to your doctor about what you should do if you are unable to collect or send data to the PDMS database as directed. • DO NOT test the Wand signal for more than 10 minutes a day. Test the Wand signal only as necessary to check the Wand signal strength and quality. Testing the Wand signal for more than 10 minutes a day may cause the Neurostimulator battery to drain more quickly than expected. • DO NOT use the Wand or laptop in temperatures above or below the recommended operating range (32oF-95oF). The Wand or laptop may not operate properly at temperatures below 32oF or above 95oF. These devices may also become warm during normal operation. DO NOT use them when the room temperature is above 95oF to avoid discomfort. • DO NOT rest the laptop on exposed skin during use. The bottom of the laptop computer may become hot during normal operation and may cause discomfort or a possible burn.
10• DO NOT set up the Remote Monitor where people can trip over the cords. The laptop power cord and phone cord may be tripping hazards, especially for small children and pets. Tripping over the cords may damage the Remote Monitor parts, and may result in bodily injury. DO NOT rest anything on the power cord. • DO NOT move the Remote Monitor to another location without first disconnecting the parts and storing them in the Carrying Case. Disconnect the Wand from the laptop, and the laptop from the wall outlet and phone jack/splitter. You may damage the parts if you do not disconnect them before moving. • You cannot make an outgoing call and send data at the same time, using the same phone number. If you need to make an emergency call while the Remote Monitor is sending data, disconnect the phone cord from the laptop. This will suspend data transmission so you can make the call. Any unsent data will be included with the data you send the next time. • DO NOT connect your Remote Monitor laptop to any type of “digital” phone line. It must be connected to an “analog” phone line. Connecting to a digital phone line will damage the laptop and not allow you to send data to the PDMS database. If you are not sure what type of phone line you have, call your phone service provider and ask them. You may also contact NeuroPace® Customer Support for assistance. Refer to the RNS® System Patient Manual for complete information on Contraindications, Warnings and Precautions related to the Neurostimulator, Leads and Magnet. Interference from electronic devices Electrical devices and appliances in and around the home emit energy when they are on. That energy can interfere with the RNS® Remote Monitor. This type of interference is called electromagnetic interference (EMI). The RNS® System is designed to operate in the presence of EMI. Some common household devices and appliances that produce EMI may temporarily affect the ability of the Wand and Remote Monitor to collect data from the Neurostimulator. Such devices include mobile phones, personal audio players, fluorescent lights, computer equipment, and home medical equipment. Appliances such as blenders, electric toothbrushes, vacuum cleaners and televisions can also produce EMI. The possibility of EMI decreases as you move the Wand and Remote Monitor further away from the device or appliance.
11In addition, using the Wand and Remote Monitor to collect data from the Neurostimulator could interfere with common household devices such as a Bluetooth headset or AM radio. The RNS® Remote Monitor has not been tested in the presence of all possible sources of EMI.
12When you should use the Remote Monitor NOTE: Completing both of the following steps on a regular basis will ensure that important information about your brain activity and about the Neurostimulator is available for review by your doctor on a timely basis. You are expected to use the Remote Monitor on a regular basis for as long as you use the RNS® System. You should 1) collect data daily from the Neurostimulator, and 2) send it to the PDMS database at least once a week.Your doctor can then make adjustments to the Neurostimulator settings during future office visits. The data also lets your doctor see when the battery is low or when there are problems with the Neurostimulator. Your doctor may direct you to collect and send data more often. CAUTION: If you are having seizures more frequently or with greater severity, talk with your doctor as soon as possible. Your doctor may ask you to collect and send data to the PDMS database on a more frequent basis until adjustments can be made to the Neurostimulator settings. Testing the Wand Signal Your Wand and Neurostimulator communicate through Radio Frequency (RF). RF is how data are collected from the Neurostimulator by the Wand and then stored in the laptop. You can test the Wand signal on the Remote Monitor laptop screen. Signal strength is higher the closer you move the Wand to the Neurostimulator. Signal quality is higher when there is little interference from other nearby electronic appliances or devices. Whenever it is time to collect data from the Neurostimulator, you can check the Wand’s signal to make sure you have positioned the Wand close enough to the Neurostimulator for data collection to occur. You should keep the Wand within about an inch of the Neurostimulator for best results. See pages 22-25 for more information on testing the Wand signal.
13Collecting and sending data through the Remote Monitor to the PDMS database Expect that it may take a few minutes to collect data from the Neurostimulator, and up to 20 minutes to send the data to the PDMS database. See pages 29-32 for information on sending data to the PDMS database. If you have problems using the Wand or laptop computer, contact NeuroPace® Customer Support.
14Setting up the Remote Monitor Step 1 Find a suitable place to set up the Remote Monitor. Make sure you review the Warnings and Precautions on pages 8-11 before choosing a location. This should be an area: • Away from water, moisture or dampness that can damage the Wand and laptop • Away from extreme temperatures (below 32oF or above 95oF) that can interfere with Wand and laptop operation • Away from small children and pets who can damage the Wand and laptop • Away from large electrical appliances that might be a source of electromagnetic interference (EMI) and interfere with Wand and laptop operation • Close to an analog phone line jack • Near an electrical wall outlet that will accept the type of power cord plug that came with your laptop. You will not be able to confirm that there are no large sources of EMI nearby until you test the Wand signal. See pages 22-25 for information on testing the Wand. Determine if the Remote Monitor will be sharing the same wall jack as your phone. If so, it is recommended that you use the Phone Splitter that is provided. This will allow you to connect 2 phone cords (one for the Remote Monitor and one for your regular phone) to the same wall jack. This way you can keep your regular phone connected at all times. • CAUTION: DO NOT connect your Remote Monitor laptop to any type of “digital” phone line. It must be connected to an “analog” phone line. Connecting to a digital phone line will damage the laptop and not allow you to send data to the PDMS database. If you are not sure what type of phone line you have, call your phone service provider and ask them. You may also contact NeuroPace® Customer Support for assistance.
Step 2 Locate the power connection symbol ( ) on the side or back of your laptop. Plug one end of the Power Cord into the laptop and the other end into an electrical wall outlet. You may need a wall outlet that accepts a 3-pronged plug. If your Power Cord comes as 2 separate pieces, first attach the 2 pieces before connecting the laptop to the wall outlet. Step 3 Skip this step if the Remote Monitor will not be sharing the same wall jack as your regular phone. Disconnect your regular phone cord from the wall jack. Connect the Phone Splitter to the phone wall jack. 15
Then reconnect your regular phone cord to the Splitter. Step 4 Locate the phone connection symbol ( ) on the side or back of your laptop. Take the phone cord (provided) and connect one end to the laptop. Then connect the other end to the wall jack (or Splitter). Step 5 Locate the USB connection symbol ( ) on your laptop. Plug the Wand cord into the USB port. Remote Monitor setup is now complete. 16
NOTE: To confirm that the Remote Monitor is set up correctly, you should: 1) Test the Wand signal (see pages 22-25) 2) Collect data from the Neurostimulator (see pages 26-28) 3) Send data to the PDMS database (see pages 29-32) If you are able to complete all 3 tasks successfully, you have properly set up the Remote Monitor. If not, See Troubleshooting on pages 42-48 for information on how to solve the problem. 17
Operating the Remote Monitor The main components of the Remote Monitor are the laptop computer with the special software installed, and the Wand. You will use the Wand to collect data from the Neurostimulator, and store it in the laptop computer. The laptop is then used to send the data over an analog phone line to a secure PDMS database that only your doctor can access. The Remote Monitor also lets you test the signal between the Wand and Neurostimulator to verify you have a strong signal. A software program installed on the laptop controls the use of the Remote Monitor. NOTE: Software screens that appear on the laptop and that are described below may not exactly match the screens that will appear on your laptop. This is due to differences in the type of laptop you may receive as part of the RNS® System. How to use the Laptop Computer Turning the laptop computer on NOTE: • Before turning on the Remote Monitor, be sure you have completed all of the setup steps on pages 14-17. • If this is the first time you are using the Remote Monitor, the laptop battery will not be fully charged until it is plugged into the wall outlet for about 2 hours. Step 1 Open the laptop display. 18
Step 2 Press the power button ( ) on the laptop to turn it on. The Home screen will appear whenever you turn the laptop on. NOTE: If the laptop does not turn on, it may not be connected to a wall outlet, or the laptop battery may be drained. Using the touchpad/button to make screen selections To use the Remote Monitor, you will need to know how to move through the NeuroPace® screens that will appear on the laptop display. Navigation is controlled with the laptop touchpad and adjacent buttons. The touchpad is located under the laptop keyboard. Below or next to the touchpad are two “clickable” buttons. The laptop keyboard is used to enter information, like your User Name Slide your finger on the touchpad to move the cursor ( ) around the laptop screen to a desired location. This is how you move about screens. The left “clickable” button is used to select an item on the screen once your cursor is in the right spot. Press and release (click) the left button to make your selection and move to the next screen. NOTE: DO NOT connect an external mouse to the laptop. 19
How to use the Remote Monitor to collect and send data to the PDMS database Step 1 Turn the laptop on to display the Home screen. Step 2 Press and hold Ctrl, Alt, and then Delete on the keyboard. Keep all keys pressed down together. The Login screen appears. 20
Step 3 NPUser should already appear in the “User Name” box. If not, move the cursor over the User name box and right click using the touchpad. Then, use the keyboard to enter NPUser in the box. This is the User Name you will see (or enter) every time you see this screen. NOTE: The User Name NPUser is not case-sensitive. Ignore the bottom “Password” box. You will leave this entry blank. Step 4 Move the cursor over the Arrow button on the screen to the right of the “Password” box. Click the Arrow button to complete the login. 21
The Main Menu screen appears. The top 3 buttons on the Main Menu screen let you perform the 3 main Remote Monitor tasks. The Exit button at the bottom lets you turn the laptop off. Testing the Wand signal The Wand is used to collect data from the Neurostimulator and store it in the laptop. Data are collected using Radio Frequency (RF) communication. Whenever it is time to collect data from the Neurostimulator, you can check the Wand’s signal to make sure you have positioned the Wand close enough for data collection to occur. You should keep the Wand within about an inch of the Neurostimulator for best results. When you test the Wand signal, 2 vertical bars will appear on the screen. One bar indicates signal Level (how strong the signal is). The second bar indicates signal Quality (if the signal is free of interference). NOTE: The signal Level and Quality bars also appear on the screen when you begin collecting data. 22
When you first set up your Remote Monitor, you should test the Wand signal to make sure there are no large sources of EMI that may affect data collection. You may need to move the Remote Monitor to another location if the signal Quality bar shows a lot of interference. Sometimes simply unplugging the Laptop from the wall outlet and using the Laptop battery power is enough to eliminate interference. You should also test the Wand signal once or twice before you actually start collecting data from the Neurostimulator. This way you will get a good sense of how Wand placement near the Neurostimulator affects signal strength. Once you know you have chosen a good location, and know how to best position the Wand, you only need to test the Wand signal if you are having problems collecting data. NOTE: Testing the Wand signal uses battery power in the Neurostimulator. There is no need the test the Wand signal more often than necessary. If you test the Wand signal for more than 5 minutes at a time, a pop-up window will appear on the screen with a message instructing you to stop. Step 1 Place the cupped side of the Wand over the Neurostimulator and rest the Wand on the scalp. It should be no more than about 1 inch away from the center of the Neurostimulator. For best results, keep the Wand directly over the Neurostimulator. Cupped side of Wand 23
Step 2 On the Main Menu screen, click the Test Wand Signal button. A pop-up window appears on the screen with 2 vertical blue bars. The first bar shows the signal Level (the current signal strength between the Wand and the Neurostimulator). The Level bar height will vary as you move the Wand closer or further from the Neurostimulator. The second bar shows the signal Quality (the current signal strength based on how free the signal is from interference). 24
Both bars will range from empty to full, with the height of the bars representing the Level and Quality of the current signal. Signal Level and Quality are considered “high” when the bars are at least half full, or more. This will typically allow for data collection to occur without interruption. If you need to adjust the Wand position to increase the signal Level, go to Step 3 below. Or, you can click the Done button on the pop-up window to go back to the Main Menu screen. Step 3 Move the Wand over the Neurostimulator until both bars are at least one half full. Try to find the spot where signal strength is as close to the maximum level as possible. You may need to unplug the laptop from the wall outlet and use battery power. Or, try moving the Remote Monitor to another location if you are unable to get the signal quality that is at least half full. Step 4 Click Done. The Wand is now properly positioned for data collection. CAUTION: Testing the Wand signal for more than 10 minutes a day may cause the Neurostimulator battery to drain more quickly than expected. Test the Wand signal only as necessary to check the signal strength and quality. DO NOT test the signal for more than 10 minutes a day. 25
Collecting data from the Neurostimulator When collecting data, you will need to position the Wand as you did in the previous section so that signal strength is at least half full. Step 1 From the Main Menu screen, click the Interrogate button. Step 2 A pop-up window with “Gathering information” appears on the screen to let you know that data collection has begun. Data collected from the Neurostimulator are stored in the laptop. NOTE: The signal strength and signal quality bars that appear when testing the Wand signal also appear here. This is to help you find the best Wand position for collecting the data. 26
If you move the Wand too far away from the Neurostimulator during data collection, the following message may appear: “Telemetry has been lost. Reposition the Wand over the Neurostimulator and try again.” Move the Wand closer to the Neurostimulator “Gathering information” reappears. This means that data collection has resumed. If you get another type of error message, follow the instructions on the screen. Then click the Retry button. Refer to the Troubleshooting section for more information on error messages that might appear. If you still need assistance, contact NeuroPace® Customer Support. Step 3 A pop-up window appears on the screen to let you know when data collection has been successful. Click the Return to Main Menu button to go back to the Main Menu screen. 27
Step 4 Now you can put the Wand down and prepare to send data to the PDMS database. 28
29Sending data to the PDMS database You will use your Remote Monitor to send data stored in the laptop to the secure PDMS database. Data are sent over an analog phone line. The Remote Monitor must first connect to the PDMS database server before data will be sent. This allows the PDMS database to identify where the data is coming from. If your Remote Monitor and phone share the same phone line, you cannot make outgoing calls or receive incoming phone calls while you are sending data. Incoming or outgoing calls will interrupt data transmission. CAUTION: You cannot make an outgoing call and send data at the same time over the same phone line. If you need to make an emergency call while the Remote Monitor is sending data, disconnect the phone cord from the laptop. This will suspend data transmission so you can make the call. Any unsent data will be sent the next time you send data. If you have “call waiting” on your phone line, you may need to temporarily disable this feature while you are sending data. Call waiting sends a call signal to your phone line that an outside call is waiting for you to pick up the call. When you are sending data, you would not be aware that the call waiting signal is coming through, but the signal may interrupt data transmission. If you have difficulty sending data, you can have Remote Monitor automatically disable call waiting whenever data are being sent. Call waiting is then automatically turned back on when data transmission is complete. See pages 35-39 for instructions on disabling the call waiting feature. NOTE: It is not necessary to disable call waiting through your phone company. Before you begin sending data, make sure your phone is not in use. Step 1 On the Main Menu screen, click the Transfer Data button.
A second screen appears that prompts you to begin. Step 2 Click the Synchronize button. 30
A pop-up window appears on the screen to let you know that the Remote Monitor is connecting to the PDMS database. Once connected, data transmission will begin. A second pop-up window shows you the status of data being sent. Allow up to 20 minutes for data to be sent. NOTE: ● If you get an error message, write down the message. You may need to refer to the message when troubleshooting or when contacting NeuroPace® Customer Support. Then click the OK button. ● If a pop-up window with a “Synchronization failed” message appears, click OK. See Troubleshooting on pages 42-48 for information on how to solve the problem. ● If data transmission stops or is interrupted, any unsent data will be stored in the laptop. It will be sent to the PDMS database with the next data transmission. 31
Step 3 When the data have been successfully sent, the Synchronization completed successfully pop-up window appears. Click the OK button. Step 4 Click the Main Menu button to return to the Main Menu screen. 32
Turning the Remote Monitor off Step 1 On the Main Menu screen, click the Exit button. Step 2 Confirm that you want to exit the program and turn the Remote Monitor off. Click the Yes button to exit or click the No button to return to the Main Menu. 33NOTE: When you are finished using the Remote Monitor, be sure to turn it off (by clicking Exit, then Yes on the Main Menu). This will help conserve laptop battery power
34and/or electricity when not in use. The Remote Monitor laptop does not automatically go into “sleep” mode if you forget to turn it off.
Changing your Remote Monitor communications settings The Remote Monitor sends your data to the secure PDMS database through a toll-free phone number that is programmed into the laptop. There are times when you may need to change the communications settings when you use the Remote Monitor in your home. Disable call waiting The call waiting feature can interrupt data transmission. You can change the Remote Monitor settings to automatically disable call waiting whenever data are being sent. Call waiting is then automatically turned back on when data has been sent. If you plan to disable call waiting, you will need to call your current phone service (or service at your current location), and ask them for the code that disables call waiting. NOTE: You only need to enter and save the code numbers once to have call waiting disabled whenever necessary. To disable call waiting, follow these steps. Step 1 Turn the laptop on and get to the Main Menu screen after the Login screen. Step 2 On the Main Menu screen, click the Transfer Data button. 35
A second screen appears that lets you begin sending data or make changes to your settings. Step 3 Click the Configure Connection button. The Phone and Modem Options window appears on the screen and lets you begin making changes. Step 4 Click on New Location. This will activate the Edit button. 36
Step 5 Click the Edit button. The Edit Location pop-up window appears. Step 6 On the Edit Location window, click the box that lets you disable call waiting. A check mark indicates the feature is disabled. 37
Step 7 Click the down arrow ( ) to the right of the box you just clicked. A drop-down list of code numbers will appear. If you see the code number you obtained from your phone service provider, click it. If it is not listed, enter the number using the keyboard. NOTE: The code number you enter and save will be used to disable call waiting every time you send data, until you either change it or delete the code number. 38
39Step 8 Click OK to save the new setting. You will return to the Phone and Modem Options window. Click OK to go back to the Main Menu screen. NOTE: DO NOT change any of the other settings on the Edit Location screen. Doing so may prevent data from being sent to the PDMS database.
40Care and maintenance The Remote Monitor does not require any special maintenance. • To remove dirt or dust from the Wand or laptop, wipe the outside with a soft cloth dampened with water and wrung out. DO NOT use any cleaning liquids or aerosols. • When not in use, the Remote Monitor should be turned off. • DO NOT store the Wand or laptop above or below the recommended storage temperature range (-40°F to 140°F). • The laptop has a rechargeable battery installed. Battery power will last about 2 hours on a full charge. The battery recharges any time the laptop is plugged into a wall outlet but it could take about 2 hours to fully charge a drained battery. If you plan to use battery power when collecting or sending data with the laptop, make sure the battery is fully charged. • If you need to move the Remote Monitor to another location, first disassemble the pieces and store them in the Carrying Case. • All laptop computers generate a moderate amount of heat when they are turned on. DO NOT cover or enclose the laptop with anything that might not allow the heat to disperse. • A shock from the buildup of static electricity may cause the Remote Monitor to stop responding. One example of when a shock might occur is after you walk across a rug and then touch the laptop. If the laptop does not respond after a shock, follow the troubleshooting instructions on pages 42-43 to restart the laptop when it does not respond. Traveling with the Remote Monitor There are a few things you need to be aware of when traveling. If you plan to take the Remote Monitor with you, make sure to disassemble the parts and store them in the Carrying Case.

45There is a lot of interference from another nearby electronic device. What to do: Make sure the Wand is properly connected to the laptop and you have positioned the cupped side of the Wand directly over the Neurostimulator. Retest the Wand signal. If the signal is low or bouncing up and down, move the Wand closer to the Neurostimulator to see if signal quality improves. If the signal quality is low, a nearby electronic device (e.g., another computer, television, microwave, etc.) may be causing interference. Try unplugging the laptop from the wall outlet. Make sure the battery is charged before doing so. If this does not solve the problem, try moving the Remote Monitor to another location and then retest the Wand signal. If your Wand signal continues to be a problem, contact NeuroPace® Customer Support for assistance. Data collection problems Problem: One of the following messages appears on the screen: “Telemetry has been lost. Reposition the Wand and try again.” “Unable to communicate with the Neurostimulator. The Wand may not be properly connected. Please reconnect the Wand and select Retry or select Cancel to continue.” Possible Cause: The Wand was moved while collecting data from the Neurostimulator. or, The Wand cord may be loosely connected or disconnected from the laptop USB port. or, There is interference from a nearby electronic device.
46What to do: Make sure the Wand is properly connected to the laptop. If this does not solve the problem, try plugging the Wand cord into a different USB port. Use the signal strength bar on the screen to help you position the Wand over the Neurostimulator to maximize signal strength. The cupped side of the Wand should be facing the Neurostimulator. Data collection should continue when the signal strength is high. If the signal quality is low, a nearby electronic device (e.g., another computer, television, microwave, etc.) may be causing interference. Try unplugging the laptop from the wall outlet. Make sure the battery is charged before doing so. If this does not solve the problem, try moving the Remote Monitor to another location and then retest the Wand signal. Data sending problems Problem: The following message appears on the screen: “There was an error encountered while communicating with the PDMS. Error Description: There is no dial tone.
