The batteries need to be replaced. Replace four new alkaline AA batteries.
Display screen is blank.
Make sure alkaline batteries with enough charge are installed.
Operation during a power failure.
This telephone operates during a power failure if a telephone line cord is
installed between the telephone wall jack and the telephone base. You
are able to answer calls with the handset, and make calls using the dialing
keys. No other features work unless batteries are installed. All settings in
menu options are retained during a power failure if a telephone line cord
is installed between the telephone wall jack and the telephone base.
If you neither install batteries nor a telephone line, after a few minutes,
the telephone clears the directory, call log history, speed dial memory, and
the last number dialed memory. At the same time, all settings in menu
options change back to the default settings.
My caller ID features are not working properly.
Caller ID is a subscription service. You must subscribe to this service from
your telephone service provider for this feature to work on your telephone.
The caller may not be calling from an area that supports caller ID.
Both your and the caller’s telephone service providers must use equipment
compatible with caller ID service.
If you subscribe to high-speed Internet service (DSL - digital subscriber
line) through your telephone line, you must install a DSL filter between
the telephone line cord and the telephone wall jack (see Telephone
installation on page 6). The filter prevents noise and caller ID problems
caused by DSL interference. Please contact your DSL service provider for
more information about DSL filters.
Make sure the area codes are set correctly.
Reset the telephone (see Common cure for electronic equipment on
page 23).
