Vehicle Alarm System (490-0712) Care and Maintenance Faxback Doc. # 31504 The Radio Shack Vehicle Alarm System with Two Remote Controls is an example of superior design and craftsmanship. The following suggestions will help you care for the system so you can enjoy it for years. Keep the system dry. If it gets wet, wipe dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Handle the system gently and carefully. Dropping it can damage the circuit boards and can cause the system to work improperly. Use only a fresh battery of the recommended size and type in each remote transmitter. Always remove an old or weak battery. It can leak chemicals that can destroy electronic circuits. Modifying or tampering with the system's internal components can cause a malfunction and might invalidate the system's warranty and void your FCC authorization to operate it. If your system is not performing as it should, take it to your local Radio Shack store for assistance. THE FCC WANTS YOU TO KNOW Your system might cause TV or radio interference even when it is operating properly. To determine whether your system is causing the interference, turn off your system. If the interference goes away, your system is causing the interference. Try to eliminate the interference by: Moving your system away from the receiver Contacting your local Radio Shack store for help If you cannot eliminate the interference, the FCC requires that you stop using your system. REPLACING A REMOTE'S BATTERY Each remote transmitter comes with a 12-volt battery installed. Replace the battery if the indicator fails to light when you press either ARM or DISARM, or if the range is reduced. We recommend an alkaline battery (such as Radio Shack Cat. No. 23-144). Follow these steps to replace the battery. 1. Use a Phillips screwdriver to remove the screw from the remote transmitter's back and lift off the top cover. 2. Remove the old battery and discard it immediately. WARNING: Never allow young children to play with a battery. 3. Insert the new battery according to the polarity symbols (+ and -) marked inside the battery compartment. 4. Replace the remote transmitter's top cover and secure it using the screw. (EB 3/22/96)
