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 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- and two-touch memory,
redial list, and all settings in the feature menu. It is recommended that you
initially install new batteries and change the batteries soon after the low
battery icon appears.
Press on the tab to open the cover of the battery compartment.

will begin to run. It will reset to the correct time when the first caller ID

Telephone installation
If you subscribe to high-speed Internet service (digital subscriber line - DSL)
through your telephone lines, you must install a DSL filter between the
telephone line cord and the telephone wall jack. The filter prevents noise and
caller ID problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL filters. Install the telephone as shown
below.
Plug one end of the coiled
handset cord into the handset
jack on the left side of the
telephone base. Plug the other
end into the handset.
One end of the telephone line
cord has been plugged into the
telephone jack on the bottom
of the telephone base. Double
check that it is plugged in firmly.
Thread the cord through the
channel and out of the mounting
area as shown.
Plug the other end of the
telephone line cord into a
telephone wall jack.
Put the handset on the
telephone base.
