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 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 only the handset and dialing keys.
