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.
