Battery installation (purchased separately)
Grasp and squeeze as the arrows
indicate to open the hinged bracket. 1.
Before using the telephone, you should install four good AA alkaline batteries
(not included) to provide memory backup and enable the use of some
features. The four AA batteries are required for the following features to work:
speakerphone, mute, flash, caller ID features, display, menu, directory, clock,
audio assist and the
IN USE light.
If you unplug the telephone from the wall jack, or you lose telephone service
for over eight minutes, and good batteries are not installed, the following
information is lost: call history, numbers stored the directory, redial, and all
settings in the feature menu. We recommend that you initially install new
batteries and change the batteries soon after the low battery icon
appears.
CAUTION: Always unplug the telephone line cord before installing
new batteries.
