Telephone operation
Line power mode (no AC power)
This telephone provides minimal functionality
during a power failure. When AC power is not
available, the screen is blank and many telephone
features do not function. Only touch-tone dialing
and volume adjustment (ringer volume and
handset volume) are supported. The telephone
uses power from the telephone line to enable you
to make and answer calls using only the handset
and dialing keys.
To make a call during a power failure
Lift the handset and wait for the dial tone. The
screen shows NO AC POWER.
Slowly dial a telephone number using the
dialing keys. Wait to hear each key tone and
make sure the digit appears on the screen
before pressing the next dialing key.
NOTE: If the telephone is not powered by the
supplied power adapter, there is a delay when
dialing digits.
To answer a call during a power failure
Lift the handset.
NOTE: The screen does not show incoming
caller ID information during a power failure.
