2 .4 power Supply and battery baCkup
The Model 400 is provided with a DC power transformer that will plug into
any standard 120 VAC outlet and a battery backup (batteries not included)
that enables the unit to continue functioning if AC power is removed (due
to electric power disruption or failure). The Model 400 uses six, C-cell alka-
line batteries. Do not use rechargeable batteries. Connect the DC power
transformer into the jack on the back of the unit and plug the adapator into
a 120VAC outlet
NOTE: Be sure that the DC transformer is plugged into an outlet before
installing batteries.
To install the batteries, remove the battery compartment door located on
the front of the unit below the keypad. Press down and slide the door away
from the unit, align batteries according to the diagram shown in Figure
2-2, and replace the hatch.

Pressing the RUN/STANDBY key on the Model 400 keypad will alternately
