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, hold, mute, flash, caller ID features, display, feature options
menu, directory, clock, and the CALL INFO light.

If you unplug the telephone from the wall jack, or you lose telephone service
for over 10 minutes, and good batteries are not installed, the following
information is lost: call list, numbers stored in the directory, redial list, 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.

1.

markings in the battery compartment.
