Getting started
Grasp and squeeze as the arrows

the battery compartment.

Battery installation
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, redial,
clock, audio assist and the IN USE light.
If you unplug the telephone from the telephone wall jack, or your telephone
service is interrupted, 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.
Press the battery compartment tab
as shown below. Lift to open the
battery compartment cover.
2.
Follow the polarity guide markings
in the battery compartment

batteries (purchased separately).
