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 28).
Important:
R If a handset is not placed on the base unit
when a power failure occurs, “Base no
power Press e” or “Press e” is
displayed. After pressing M
N 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
/ .
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 socket using a
telephone double adaptor.
R Calls cannot be made during a power
failure until key lock is turned off (page 18).
R If “Please wait for 1 minute.” is
displayed, please do not operate the unit
until the message disappears.
