Powering the Unit
The unit can be powered by connecting the attached AC cord to a standard AC outlet
(10V~60Hz).
A 9-Volt battery can be inserted into the unit to serve as a back-up in case the power
goes out.
Please note, the back-up battery is not meant to power the unit at all times, but only in
case of an emergency or unexpected circumstances.
