Only qualified service workers are authorized to
repair your phone. Unauthorized repair and
modifications void the Manufact
urer’s warranty!
„Cannot make
phone call
”
Make sure the number you are dialing is
correct. If you make an international phone
call, dial a country code before the actual
number (eg. 0049 or +49 for Germany).
If you have a prepaid card, make sure,
there are sufficient funds available on the
card to place a phone call.
„No SIM card,
emergency
calls only
(112)”
Make sure the SIM Card is installed
correctly
“The phone
does not work.
The phone
does not charge
when plugged
in
”
The phone might be switched off. To
switch it on, press the power key (red
receiver) for about 3 seconds.
If you have not used the phone for a long
time, the battery might be “deeply-
discharged”; to recover a deeply-
discharged battery leave your charger
plugged in, although there will be no image
on the display.
„Can I place a
phone call while
abroad
?”
If you are out of the country and
ROAMING is enabled, your phone
automatically will use the foreign
telephone network. To learn more, contact
your service provider
