Power back-up operation
for landline
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 landline 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
“

adaptor) to the same telephone line or to
the same telephone line socket using a
telephone double adaptor (for Australia)/a
BT double adaptor (for New Zealand).
