Getting started
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 corded handset volume adjustment
are supported. The telephone uses power from the telephone line to enable
you to make and answer calls on Line 1 only using the corded handset and
dialing keys.
After you install your telephone or the power returns following a power outage,
the telephone base or cordless handset will prompt you to set the date and
time. For instructions, see Set date and time on page 37 for details. To skip
setting the date and time, press CANCEL or BACK on the telephone base, or
press
OFF/CANCEL or BACK on the corded handset.
To make a call during a power failure
Lift the corded handset and wait for a dial tone. The screen displays
No AC power. System can only access Line 1.
Slowly dial a telephone number using the dialing keys. Wait to hear each
key tone upon inputting a digit before pressing the next dialing key.
NOTE: When 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 corded handset.
NOTE: The screen does not show incoming caller ID information during a power failure.
