Battery Installation - AT&T CL2940 Quick Start Manual

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, display, menu, directory, redial,
clock, Audio Assist® and the INCOMING CALL light.
If you unplug the telephone from the telephone wall jack, and good batteries
are not installed, the following information will be lost: call log history,
directory entries, speed dial entries, 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
