Check PIN code
When the Check PIN code feature is enabled, you must enter your PIN each time you switch on the phone. This
means that any person who does not know your PIN cannot use your phone without your approval.
Note: You must enter the PIN code to enable or disable the Check PIN Code feature.
1. From Idle mode, press Menu ➔ Settings ➔ Phone settings ➔ Security ➔ Check PIN code.
2. Choose Enable to have the phone prompt you for the PIN each time you power it on. Choose Disable to have
the phone connect directly to the network when you power it on.
Change PIN code
This feature allows you to change your current PIN, provided that the Check PIN code feature is enabled. You must
enter the current PIN before you can specify a new one.
