Initial basic settings
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.
Aer 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. 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.
We recommend you program your telephone system before use. The following
are a few examples of common features to set before using the telephone. Refer to
the Handset and telephone base settings and Answering system settings in the
Complete user’s manual for detailed instructions on setting all telephone features.
