Installation
Installing the backup battery in the base unit
A rechargeable NiMH battery works as emergency power during a power failure. The fully
charged backup battery provides the base unit with a minimum of 20 minutes operation.
The battery is charged in the base unit while the AC adaptor is connected (page 12). It
takes approximately 16 hours to charge fully.
Note:
L The battery cannot be overcharged.
L If the backup battery has been discharged, the unit will not work during a power failure.
If required, the unit can be replaced with a standard telephone to restore service during
the power outage.
1 Open the battery cover.
2 Install the backup battery in the
battery compartment. Plug in
battery connector as
shown, and close the
battery cover.
BATTERY indicator:
L The BATTERY indicator lights while the
battery is being charged. (This is
normal.)
L During a power failure (or if the AC
adaptor is disconnected), the BATTERY
indicator shows the battery strength:
Blinking slowly: The unit is operating
from the battery backup.
Blinking fast: The battery is not
connected, defective or
non-chargeable.
