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 power 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).
Y
Display during charging.
Charging time
An empty battery is fully charged
after 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.
Extreme temperatures considerably
reduce the phone’s standby time.
Avoid placing the phone in the sun
or on a heater.
Call time: Up to 330 minutes
Stand-by 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
included 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
after 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.
