Troubleshooting
The phone does not
switch on
Remove and reinstall the bat-
tery (see page 7). Then charge
the phone until the battery
icon has stopped flashing. Fi-
nally, unplug from the charg-
er and try to switch the
mobile on.
The display shows
BLOCKED when
you switch on
Somebody tried to use your
phone but didn’t know the
PIN code nor the unblocking
code (PUK). Contact your
service provider.
The and
symbols are not dis-
played
The network connection is
lost. Either you are in a radio
shadow (in a tunnel or be-
tween tall buildings) or you
are outside the network cover-
age area. Try from another
place or contact your network
operator for assistance/infor-
mation about the network.
The display doesn't
respond (or the dis-
play responds slow-
ly) to key presses
The display responds more
slowly at very low tempera-
tures. This is normal and does
not affect the operation of the
phone. Take the phone to a
warmer place and try again.
In other cases please contact
your phone supplier.
Your phone doesn’t
return to the idle
screen
Press and hold
c
, or
switch off the phone, check
that the SIM card and the bat-
tery are installed correctly,
and switch it on again.
Your phone doesn’t
display the phone
numbers of incoming
calls
This feature is network and
subscription dependent. If the
network doesn’t send the call-
er’s number, the phone will
display
Call 1
instead. Contact
your operator for detailed in-
formation on this subject.
You can’t send text
messages
Some networks don’t allow
message exchanges with other
networks. Contact your oper-
ator for detailed information
on this subject.
