PIN code change procedure
1. Select 'PIN code' from the 'Change codes' list and
then press [OK].
2. Input the current PIN code, and press [OK].
3. Input the new PIN code, and press [OK].
4. Input the new PIN code once again, and press
[OK].
- If the PIN code is different from that of step 3,
the procedure is restarted from step 3.
5. When the PIN code is changed properly, a
"Changed" message is displayed. If you enter an
incorrect PIN code in step 2, the procedure is
restarted from step 2, and the number of
attempts you have left to enter the number
decreased by 1.
6. Press the C key in the PIN code input window to
return to the previous step.
Note
] Three incorrect PIN code entries in the PIN
code input window would invalidate the PIN
code. In this case, you have to input the PUK
(PIN Unblock Key) code to configure the PIN
code again. The maximum allowed number of
attempts of PUK code input is 10 times.
ATTENTION: after having entered 10 times an
incorrect PUK code, the USIM card will be
blocked and must be replaced.
PIN2 code
PIN2 is the abbreviation of Personal Identification
Number 2, and is used to restrict the use of
unauthenticated users like PIN. The PIN2 code
change procedure is the same as the one for the PIN
code. 3 incorrect PIN2 code entries would invalidate
the PIN2 code. In this case, you have to input the
PUK2 code in order to use the PIN2 code again. The
maximum allowed number of attempts of PUK2 code
input is 10 times, like PUK1. 10 incorrect PUK2 code
entries would invalidate the PIN2 code.
