Battery charging
To extend the service life of the batteries:
• Charge batteries at least 15 hours before initial use of handset. To attain
maximum power output, complete three to five charge and discharge
cycles are required.
• Charge regularly.
• Avoid extreme temperatures as they affect the charging capability.
To charge batteries: Place the handset on the charging
unit.
Charge Display
The battery icon
, which is located at top left of the display, indicates bat-
tery charging status. Each bar of the battery icon represents about 1/3 of
maximum charging capacity. When the handset is placed in the charger, flash-
ing segments indicate that charging is taking place.
• The charging status indicator is only relevant after the first charging cycle
has completed.
• Switching the handset Off and On, or replacing the batteries results in
loss of the battery capacity status. The charging status indicator is only
relevant after the next charging cycle has completed.
• After a complete discharge of the batteries, the charging status symbol
appears after a few minutes of charging.
Charge Warning
If the telephone beeps and the empty battery icon displays, batteries require
charging. During a call, the handset switches off after a few minutes.
