Charging the battery

Charging the battery
The battery is not fully charged
when delivered. Plug charger cable
into the bottom of the phone, plug
power supply unit into a mains pow-
er socket and charge for at least
two hours.
As an alternative, the battery can be
charged via the USB port (see
Accessories: USB data cable).

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. If the temperature
rises/falls 5 °C above/below this, the
charge symbol flashes a warning. The
mains voltage specified on the power
supply unit must not be exceeded.
Operating time
The operating time depends upon
the respective conditions of use. Ex-
treme temperatures considerably re-
duce the phone's standby time.
Avoid placing the phone in the sun
or on a heater.
Call time: 100 to 330 minutes
Stand-by time: 60 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 in-
cluded in delivery!
Display while in service
Charge level display during opera-
tion (empty–full):
V W X
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 finish the
charging process prematurely.
Additional information
The power supply unit heats up when used
for long periods. This is normal and not
dangerous.
If the battery is removed for longer than
30 seconds, the clock must be reset.
