User's Manual

In cases where the power loss was caused simply by accidentally unplugging the unit,
this notification prompts to reconnect it.
Upon completion of an offender’s program and the Receiver’s service is ended, the
backup battery is automatically disconnected. This preserves the backup power so it will
be available immediately when the unit is activated at the next offender’s premises.
