Power back-up
operation
When a power failure occurs, the
charged handset temporarily supplies
power to the base unit (power back-up
mode). This allows you to make and
receive calls using a handset during a
power failure. The base unit will not
perform any other functions. However,
some functions such as Caller ID and
shared 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 29).
Important:
R If a handset is not placed on the base
unit when a power failure occurs,
“Base no power Press OFF” is
displayed. After pressing MOFFN on
the handset, place it on the base unit
to start power back-up mode.
R Power back-up mode will not work if
the battery level of the power
supplying handset is or .
R Do not lift the power supplying
handset from the base unit during
power back-up mode.
R Do not touch the handset’s charge
contacts during power back-up mode.
R If the battery level is low, the unit will
not work sufficiently during power
back-up mode. In addition, in case
handset battery power runs out, we
recommend connecting a corded-type
telephone (without AC adaptor) to the
same telephone line or to the same
telephone line jack using a Panasonic
T-adaptor (page 4).
