Charging the battery

Charging
The battery is not fully charged
when delivered. Plug the charger ca-
ble into the bottom of the phone,
plug the power supply unit into a
mains power socket and charge for
at least two hours (for charging via
USB, see page 96). Do not interrupt
the charging procedure
prematurely.

Charging time
An empty battery is fully charged af-
ter about 2 hours. Charging is only
possible within a temperature range
of +5°C to +45°C (+41°F to +113°F)
If the temperature rises/falls 5°C
above/below this, i.e drops to 32°F
or rises to 122°F, the charge symbol
flashes a warning. The mains voltage
specified on the power supply unit
must not be exceeded.
Display when charging is
in progress.
Operating time
The operating time depends upon
the respective conditions of use.
Extreme temperatures considerably
reduce the phone's standby time.
You should therefore avoid the leav-
ing the phone in the sun or on a
radiator.
Talktime: up to 300 minutes
Standby time: up to 300 hours
Charge icon not visible
If the battery has been discharged
fully, the charge icon is not immedi-
ately visible when the power supply
is plugged in. It will appear after up
to two hours. In this case the battery
is fully charged after 3 to 4 hours.
Only use the plug-in power supply unit
included in delivery!
Display during operation
Charge level display during
operation (empty–full):
Ý Þ ß
A beep sounds when the battery is
nearly empty. The charge level of the
battery is only displayed correctly af-
ter an uninterrupted charging/dis-
charging cycle. You should therefore
not remove the battery unnecessarily
and where possible not terminate the
charging process before completion.
