when delivered. Plug the charger
cable into the bottom of the phone,
plug the power supply unit into a
mains power socket and charge for
at least two hours.

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 times
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.
Talktime: up to 300 minutes
Standby time: up to 250 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 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. Therefore do not
remove the battery unnecessarily , and
where possible, do not end 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.
