ACKUP
Installation of an optional 9V battery
enables the phone to work normally in the
event of a power loss. Without the battery
backup:
• The phone will not operate for incoming
calls.
• You must use the handset; the phone
automatically defaults to Line 1.
With or without the battery backup, phone
numbers stored in memory are not lost
during a power outage.
NOTE:
In order to maximize battery
operation, we recommend that you use the
handset rather than the speakerphone
during a loss of power.
