INSTALLING/REPLACING THE BATTERY
The module is powered by one 9-volt battery. For the longest operation, we rec-
ommend you use an alkaline battery (Radio Shack Cat. No. 23-553). Even if you
use the supplied AC adapter, install a battery to keep the information in the mod-
ule’s memory during power failures. When the battery low indicator (
) ap-
pears in the top left corner of the display or the display dims, replace the battery.
Cautions:
• Do not press any buttons after you remove the battery. Doing so can delete
all caller information from the module.
• Be sure to keep one fresh 9 volt battery on hand when you replace the bat-
tery. You need to replace the battery within 20 seconds before the display
blanks out. Otherwise, the information stored in the module’s memory will
be lost.
