Battery Life
Battery life depends on how far the handset is from the base, and other
environmental conditions.
NOTE: For optimum performance, charge your handset on the base
every night.
Charge the Handset Battery Pack
This battery should remain charged for up to five days. A fully charged
battery provides an average talk time of about six to eight hours.
The battery pack needs charging when:
– The battery icon ( ) flashes,
– A warning tone sounds, or
– The screen displays LOW BATTERY when idle.
Place the handset in the base so the CHARGING light goes on. The
battery pack is typically charged in eight hours. For best results,the
initial charge should be twelve hours.
You can keep the battery fully charged by returning the handset to the
base after each use.
If you repeatedly get a Low Battery indicator,even after eight hours of
charging,the battery should be replaced.
