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).
