2. Battery installation and
charging
Before you can use your new phone, you need to attach and
charge the battery.
Attaching the battery
To attach the battery, place it
on the back of the phone as
shown and slide it toward the
top of the phone until it clicks
into place.
Battery charging
Your phone is powered by a rechargeable NiMH or Li-Ion
battery. Note that a new NiMH battery’s full performance is
achieved only after two or three complete charge and discharge
cycles. For charging times, see ‘Charging times’ on page 65.
How to charge your battery
Connect the lead from the charger to the bottom of your
phone or to a charging stand. Then plug the charger into a
standard wall outlet.
When the battery is charging, the battery strength indicator
on the right side of the display scrolls.
Note: When you charge the battery for the first time, the
battery strength indicator will not scroll the entire time; this
is normal.
Problems charging
If your phone displays Not charging, charging is suspended.
Check that the battery is connected to an approved charging
device. If the battery is very hot or cold, wait for a while;
charging will automatically resume after the battery is
restored to its normal operating state. If charging still
fails, contact your dealer.
