animals to pass through undetected. The Base Station is powered by the AC adapter and the 4 AA batteries supply power in case of a
power outage.

Batteries:
If the AC adapter is not connected, the
AA batteries in the Base Station should last up to one week.
If the Base Station batteries are low, the Base Station will
beep every 30 minutes. The AA batteries in the PIR Motion
Sensor will last up to 2 years depending on use (lithium
batteries are recommended for colder environments). If
the PIR Motion Sensor batteries are low, the Base Station
will beep every 30 minutes until the batteries are replaced.
The PIR Motion Sensor will continue to operate with a
low battery, however the light will not illuminate. For peak
performance, inspect batteries annually and replace as
needed.
Programming Additional PIR Motion Sensors:
The Base
Station can learn the code of up to 7 additional PIR Motion
Sensors, responding with unique buzzes. To program
additional PIR Motion Sensors see Step 4.
To order additional PIR Motion Sensors call
1-800-528-9131.
