Installing the Batteries for the Battery Back-Up
1. Remove the battery compartment door located on the bottom of the main unit.
2. Follow the polarity markings inside the battery compartment, and insert 2 x AAA batteries (not
included) into the two battery slots located in the battery compartment.
3. Replace the battery door.
NOTES:
When replacing the back-up batteries, do not disconnect the AC power cord from the wall outlet. If you
do, all the current date time and alarm settings will be erased.
If the unit will be left unplugged for a long period of time, remove the batteries to avoid any damage that
may occur if the batteries leak and cause corrosion.
1.) Danger of explosion if the battery is replaced incorrectly.
2.) Replace only with the same or equivalent type battery.
3.) Insert the battery holder back into the battery slot.
