Device and SIM card security
To change the PIN code, select Phone and SIM card > PIN code. The new code must
be 4 to 8 digits long. The PIN code protects your SIM card against unauthorised use and
is provided with the SIM card. After three consecutive incorrect PIN code entries, the
code is blocked, and you need to use the PUK code to unblock it before you can use the
SIM card again.
To set the keypad to lock automatically after a defined period, select Phone and SIM
card > Keypad autolock period.
To set a time-out after which the device is automatically locked and can be used only if
the correct lock code is entered, select Phone and SIM card > Phone autolock
period. Enter a number for the time-out in minutes, or select None to set off the
autolock period. When the device is locked, you can still answer incoming calls, and calls
may still be possible to the official emergency number programmed into your device.
To set a new lock code, select Phone and SIM card > Lock code. The preset lock code
is 12345. Enter the current code and then the new code twice. The new code can be
4-255 characters long. Both alphabets and digits can be used, and both uppercase and
lowercase alphabets are possible. The device notifies you if the lock code is not properly
formatted.
Restore original settings
To restore the original device settings, select Menu > Ctrl. panel > Settings and
General > Factory settings. To do this, you need your device lock code. After resetting,
the device may take a longer time to switch on. Documents, contact information,
calendar entries, and files are unaffected.

To use a specific positioning method to detect the location of your device, select
