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.
