Getting started

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 caller ID features and the IN USE light to work. If
good batteries are not installed, the display only works when you
lift the handset.
If you unplug the telephone from the telephone 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 one-touch and two-touch memory, redial list, and all
settings in the feature menu. It is recommended that you install
new batteries soon after the low battery icon appears.
Follow the steps below to install the batteries:
1. Press on the tab and lift to open the cover of the battery
compartment.
Press this
tab to
release.
Lift this
tab to
open.
