Using the phone during a power
failure
During a power failure, you can making or receiving calls.
When making a call, you can only use the dialing keys.
Notes
• You cannot operate thé phone other than for making or receiving calls.
• Since the speakerphone does not function during a power failure, you should
use the handset when making or receiving calls.
• There is no effect on the memory.
Setting the LINE SELECT AT POWER FAILURE
switch
You cannot switch line 1 and 2 during power failure, so set the LINE
SELECT AT POWER FAILURE switch to L (line) 1 or L (line) 2 to set
the active line. Only the selected line is used for making or receiving
calls during a power failure.
For example, if a power failure occurs while you are using line 2 with
the LINE SELECT AT POWER FAILURE switch set to LI, the
connecting line automatically changes to line 1, and line 2 is
disconnected.
