Troubleshooting
Operation during a power
failure.
My caller ID features are
not working properly.
•
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 dial calls using the dial pad keys and the
REDIAL key. 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 there are no batteries installed and the
telephone is plugged into a telephone wall
jack, when you lift the handset the screen
display works using the power from the
telephone line. For more details about the line
power, contact your telephone service provider.
•
If you neither install batteries nor telephone
line cord in this telephone, after eight
minutes, the telephone automatically clears
the directory, call history, two-touch memory
locations, and the last number dialed memory.
At the same time, all settings in menu options
change back to the default ones.
•
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 might 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.
