Change of access codes (Menu 4-6-6)
With this menu you can change the access codes: security code, PIN code, PIN2 code and barring
password. These codes can only include the characters 0 to 9. The phone prompts you to enter the
current code and the new code. It also prompts you to verify the new code by entering it again.
Note: Avoid using access codes similar to the emergency numbers, such as 112, to prevent
accidental dialling of the emergency number.
