Battery Installation - AT&T CL2909 User Manual

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 the following features to work:
speakerphone, hold, mute, flash, caller ID, screen 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 a few 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
CAUTION: Always unplug the telephone line cord before installing new
batteries.
1. Press down on the battery
compartment cover tabs as shown
and pull to open the battery
compartment cover.
2. Insert four AA alkaline batteries
(not included) following the
polarity markings in the battery
compartment.
3. Close the battery compartment
cover as shown, making sure the
cover snaps into place.
NOTE: If there are no batteries installed and the telephone is plugged into
a telephone wall jack, the screen display operates using the power from the
telephone line when you lift the handset. When operating in this mode, the
screen display may be dimmer than usual.
