Lock code (5 digits) - The lock code can be used to lock the phone and keypad
to avoid unauthorized use.

The factory setting for the lock code is 12345. To avoid unauthorized use of
your phone, change the lock code. Keep the new code secret and in a safe
place separate from your phone.

•

PUK and PUK2 codes (8 digits) - The PUK (Personal Unblocking Key) code is
required to change a blocked PIN code. The PUK2 code is required to change a
blocked PIN2 code. If the codes are not supplied with the SIM card, contact
the operator whose SIM card is in your phone for the codes.

You can change the following codes: lock code, PIN code, and PIN2 code. These
codes can only include the numbers from 0 to 9.

Avoid using access codes similar to emergency numbers, such as 911, to prevent
accidental dialing of the emergency number.

- When the PIN code request is active, the code is requested each

time the phone is switched on. Note that deactivating the PIN code request may

emergency number).

Lock if SIM changed

- Select

Yes

if you want the phone to ask for the lock code

when an unknown, new SIM card is inserted into your phone. The phone maintains
a list of SIM cards that are recognized as the owner’s cards.

Fixed dialing

- You can restrict your outgoing calls to selected phone numbers, if

supported by your SIM card. You need the PIN2 code for this function. When this
function is active, you can only call those phone numbers that are included in the
fixed dialing list or which begin with the same digit(s) as a phone number on the list.
