The phone lock protects the phone against unauthorised
use. You can change the phone lock code (0000 by default)
to any four-digit code.
To edit your phone lock code
1 From standby select Menu > Settings > the General
tab > Security > Locks > Phone protection
> Change code.
2 Enter the current code and select OK.
3 Enter a new code and select OK.
4 To confirm, re-enter the new code and select OK.
To unlock the phone
1 From standby select Menu > Settings > the General
tab > Security > Locks > Phone protection
> View code.
2 Enter your phone lock code and select OK.
3 Select Off.
If the phone protection is set to Off, you do not need
to enter your phone lock code unless a different SIM
card is inserted in the phone.
If you forget the new code, you have to take the
phone to your local Sony Ericsson retailer.
