battery, the LED
indicator blinks
rapidly, but the
handset does not
beep.
The temperature of the

outside of normal limits.
Confirm that the area where
the handset is being

℃
(41
℉
) and 40

),
and wait for the battery’s

While charging the
battery, the LED
indicator blinks
rapidly and the
handset beeps
rapidly.
The battery is not
charging correctly due to
an electrical failure.
Unplug the AC adaptor from
the AC outlet, remove the

and contact your phone
system dealer/service
provider.
A wrong type of battery
such as Alkaline or
Manganese was inserted.
