Getting started

Grasp and squeeze as the arrows

indicate to open the hinged bracket.

Battery installation (purchased separately)

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 telephone wall jack, or you lose telephone

service for few 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.

Press the battery compartment

tabs as shown below. Lift to open

the battery compartment cover.

Follow the polarity guide markings

in the battery compartment

to insert four new alkaline AA

batteries (purchased separately).

3. Replace the battery compartment

cover. Make sure the cover snaps

into place.
