Charge Handset Battery
After battery installation, there may be enough power for some short calls. For
optimal performance, we recommend that you place the handset in the charger and
allow the battery to charge for 16 hours before use. The CHARGE light on the
handset charger will be lit to indicate that the handset is charging. You can keep
the battery charged by returning the handset to the charger after each use. When
the battery power is completely depleted, a full recharge takes about 16 hours. If
the handset will not be used for a long period, remove the battery to prevent
possible leakage.
After the battery is fully charged, you can expect the following performance:
Operation
Operating time
While in use (handset/headset)
7 hours
While in use (Speakerphone)
5 hours
While in use (Internet browsing)
3 hours
While not in use (standby*)
100 hours
#
* Handset is off the charger but not in use.
# The operation time in standby mode decreases to approximately 50 hours if the keypad is blinking to indicate you
have new voicemail.
The battery needs charging when:
•
A new battery is installed in the handset.
•
The battery indicator on the handset display is flashing and empty.
