Battery installation

Before using the telephone, install four good AA alkaline batteries
(not included) to provide memory backup, and to enable features
such as caller ID and the IN USE light. If good batteries are not
installed, the display only works when you lift the handset. When
operating in this mode, the display may be dimmer than usual.
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 speed dial memory, last number redial,
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 batteries:
1. Press on the tab and lift
to open the cover of the
battery compartment.
Press this tab
to release.
3. Close the battery compartment cover. Make sure it clicks into place.
Lift this tab
to open.
2. Install four new AA batteries
(not included) in the battery
compartment according to
the engraved labels, + and -,
in the compartment. Place
the batteries above the
