NOTE: This telephone provides minimal functionality during a power outage. When AC power is not available, many telephone features do not function. The telephone uses power from the telephone line to enable you to make and answer calls using only the corded handset and dial pad keys. However, when more than one telephone on the same line is being used simultaneously, there might not be sufficient power to operate your telephone in the event of a power failure.
