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.
When is charging complete?
When the battery strength indicator stops
scrolling, your phone is considered fully charged.
However, a slight increase in charge may occur if
you leave your phone connected to the charger.
Note: If you are using a lithium ion battery,
continue to charge it for two hours after the indicator has
stopped scrolling to retain “trickle charge”.
When is a good time to charge?
You can charge anytime, but remember that when your
phone displays Battery low, you only have a couple of
minutes of talk time left.
Can I make calls while charging?
Yes, but your battery may not charge during a call. Charging
should resume once you end the call.
Discharging NiMH batteries
For good operation times, discharge NiMH batteries from
time to time by leaving your phone switched on until it
turns itself off (or by using the battery discharge facility of
any approved accessory available for your phone). Do not
attempt to discharge the battery by any other means.
Removing the battery
Note: Switch off the phone before removing the battery!
