Power backup operation
for landline

handset during a power failure. The base unit
will not perform any other functions. However,
some functions such as Caller ID and
phonebook are available only when using a
handset other than the handset supplying
power to the base unit. You can program
"Power failure" and the default setting is
"Auto" (page 59).

when a power failure occurs, "Power
outage Press OFF" is displayed. After
