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. You can program
"Power Failure" and the default setting is
"Auto" (page 30).

Important:
L If a handset is not placed on the base unit
when a power failure occurs, "Base no
power Press OFF" is displayed. After
pressing {OFF} on the handset, place it on
the base unit to start power back-up mode.
L Power back-up mode will not work if the
battery level of the power supplying
handset is d or 0d4.
L Do not lift the power supplying handset from
the base unit during power back-up mode.
L Do not touch the handset's charge contacts
during power back-up mode.
L 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 T-
adaptor.
