Solving Problems
If you are experiencing problems with your phone, perform the
following simple checks before contacting a service professional.
This may save you the time and expense of an unnecessary service
call.
When you switch your phone on, the following messages may
appear:
Insert SIM Card
♦
Check that the SIM card is correctly installed.
Phone Locked Enter Password
♦
The automatic locking function has been enabled. You must enter
the phone’s password before you can use the phone. The factory
preset code is "00000000".
Enter PIN
♦
You are using your phone for the first time. You must enter the
Personal Identification Number (PIN) supplied with the SIM card.
♦
The PIN Check feature is enabled. Every time the phone is switched
on, the PIN has to be entered. To disable this feature, use the PIN
Check menu (Menu 9.7.1).
Enter PUK
♦
The PIN code was entered incorrectly three times in succession
and the phone is now blocked. Enter the PUK supplied by your
service provider. There is a PUK1 and a PUK2 code. Please make
sure you know which one is locked and apply the correct PUK
code.
