Locks
SmartChip lock
This lock only protects your subscription.
Your phone will work with a new
SmartChip. If the lock is on, you have to
enter a PIN (Personal Identity Number).
If you enter your PIN incorrectly
three times in a row, the SmartChip
is blocked and you need to enter your
PUK (Personal Unblocking Key). Your
PIN and PUK are supplied by AT&T.
To unblock the SmartChip
1 When PIN blocked appears, enter your
PUK and select OK.
2 Enter a new four-to-eight-digit PIN
and select OK.
3 Re-enter the new PIN and select OK.
To edit the PIN
1 From standby select Menu > Settings
> the General tab > Security > Locks
> SmartChip protection > Change
PIN or Change PIN2.
2 Enter your PIN and select OK.
3 Enter a new four-to-eight-digit PIN
and select OK.

OK.
To use the SmartChip lock

> the General tab > Security > Locks
> SmartChip protection > Protection.
2 Select an option.

Phonelock
You can stop unauthorized use of
your phone. Change the phonelock
code (0000) to any four-to-eight-digit
personal code.
If you select a city, My time zone also
updates the time when daylight saving
time changes.
If Codes do not match appears, you
entered the new PIN incorrectly.
If Wrong PIN appears, followed by
Old PIN:, you entered your old PIN
incorrectly.
It is important that you remember your new
code. If you forget it, you have to take your
phone to your local Sony Ericsson retailer.
