• Lock code (5 digits) - The lock
code can be used to lock the
phone and keypad to avoid
unauthorised use.
Note: The factory setting for
the lock code is 12345. To
avoid unauthorised 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.
Note: Avoid using access
codes similar to emergency
numbers, such as 112, to
prevent accidental dialling
of the emergency number.
PIN code request - 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 not be
allowed by some SIM cards.

Autolock period - You can set an
autolock period, a time-out after

correct lock code is entered. Key in a

or select None to turn off the
autolock period.
• To unlock the phone, key in the
lock code.
Note: When the phone is
locked, calls may be possible
to the emergency number
programmed into your
phone (e.g. 112 or other
official emergency number).
Lock if SIM changed
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 recognised as the
owner's cards.
Fixed dialling - 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 dialling list or which begin
with the same digit(s) as a phone
number on the list.
