Arm-A-Dor

The standard Arm-A-Dor unit runs off of two 9 volt batteries. When these batteries get low the unit will begin to beep once every 8-10 seconds.

To change the batteries you need to remove the endcap furthest away from the keycyinder exposing the batteries.
Remove the batteries and replace with fresh 9 volt batteries.

Place endcap back on and arm unit.
