You can use the access codes described in this section to avoid 
unauthorised use of your phone and SIM card.

The access codes (except PUK and PUK2 codes) can be changed by 
using Menu 4-6-6. See the following section.

The security code can be used to avoid unauthorised use of your 
phone. The security code 12345 is usually supplied with the phone. 
Change the security code before you start using your phone. Keep 
the new code secret and in a safe place, which is separate from the 
phone.

If you key in an incorrect security code five times in succession, the 
phone will not accept the correct code for the next five minutes.

The PIN (Personal Identification Number) code protects your SIM 
card against unauthorised use. The PIN code is usually supplied with 
the SIM card. When the PIN code request is enabled (Menu 4-6-1), 
the code is asked each time the phone is switched on.

If you key in an incorrect PIN code three times in succession, key in 
the PUK code and press OK. Key in a new PIN code and pressOK. Key 
in the new code again and press OK.

The PIN2 code, supplied with some SIM cards, is required to access 
some functions, such as charging unit counters. These functions are 
only available if supported by your SIM card.
