There are several access codes that are used by 
your phone and its SIM card. These codes help you 
protect the phone against unauthorised use.

Some access codes can be changed using the 
Security menu option (Menu 4.4). See page 111 
for further details.

The Phone lock feature (see page 112) uses the 
phone password to protect your phone against 
unauthorised use. 

The phone password is supplied with the phone and 
is preset to “00000000” at the factory. To change 
the password, use the Change password menu 
option (Menu 4.4.4). See page 112.

The PIN (Personal Identification Number) protects 
your SIM card against unauthorised use. It is 
usually supplied with the SIM card. When the PIN 
Check feature is enabled (see page 111), you must 
enter the PIN each time you switch on the phone.

If you key in an incorrect PIN three times in 
succession, key in the PUK and press the Ok soft 
key to unlock the phone. Key in a new PIN and 
press the Ok soft key. Key in the new PIN again and 
press the Ok soft key.
