Security settings
Select Menu > Tools > Settings > General > Security.
Define the following security settings:
• Phone and SIM card — Adjust the security settings for
your device and SIM card.
• Certificate management — Manage your security
certificates.
• Security module — Manage your security module.
Avoid using codes that are similar to emergency numbers to
prevent accidental dialling of the emergency number. Codes
are shown as asterisks. When you change a code, enter the
current code, then the new code twice.
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 Factory
settings. To do this, you need your device lock code. After
resetting, the device may take a longer time to power on.
Documents, contact information, calendar entries, and files
are unaffected.
