You can reset some of the menu settings to their original values. Data that you
have entered or downloaded is not deleted (for example, entries in your contacts
list are not affected).

1. In the standby mode, select Menu> Settings> Other settings> Restore settings.
2. Enter the lock code, and select OK

Note:Depending on your wireless service provider, your device may
request the security code (defaulted to 12345) instead of the lock code.
