Operating time
The operating time depends upon
the respective conditions of use. Ex-
treme temperatures considerably re-
duce the phone’s standby time. You
should therefore avoid leaving the
phone in the sun or on a radiator.
Talktime: up to 300 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 unit
included in delivery!
Display during operation
Charge level display during
operation (empty–full):
Э Ю Я
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 .
