Alarm Unit Low Battery Warning
Your DEFCON 3 Security System warns you when it detects a low battery condition. Upon arming or disarming your alarm unit, you will hear an extended low tone in addition to the usual one or two beeps. When you hear this tone, replace the batteries as soon as possible.
If this occurs while you are traveling, don't worry - the DEFCON 3 Security System is designed to offer several more days of service beyond the initial warning. Please dispose of used batteries safely.
Alarm Unit Tips
Remember to secure the battery cover screw to prevent tampering with your DEFCON 3.
To conserve battery power while the DEFCON 3 Security System is not in use, turn the end of the cable counterclockwise until the alarm unit beeps three times. After approximately 30 seconds, the alarm will no longer respond to signals from the remote control. During those 30 seconds, however, the alarm will sound if any button on the remote control is pressed. If this happens, press and hold any button on the remote control to deactivate the alarm siren.
For best results, replace alarm unit batteries every 90 days. Never combine old and new batteries.
Whenever you insert or replace the batteries in the alarm unit, the LED lights will flash alternately to indicate that the alarm unit is waiting for a signal from the remote control. You must press and hold either button on the remote control until the alarm beeps six times and the LED lights stop flashing.
Caution: For security reasons, some airlines may require that you remove this kind of device from your luggage or personal
