Security
The Security feature enables you to restrict the use of your phone by others and to
restrict the types of calls.
Various codes and passwords are used to protect the features of your phone.
PIN check
When the PIN Check feature is enabled, you must enter your PIN each time you
switch on the phone. Consequently, any person who does not have your PIN cannot
use your phone without your approval.
Note: Before enabling or disabling the PIN Check feature, you must enter your PIN.
The following options are available:
- Disable : the phone connects directly to the network when you switch it on.
- Enable : you must enter the PIN each time the phone is switched on.
Change PIN
This feature allows you to change your current PIN, provided that the PIN check
feature is enabled. You must enter the current PIN before you can specify a new one.
Once you enter a new PIN, you are asked to confirm the PIN number by
re-entering it.
Phone lock
When the Phone lock feature is enabled, the phone is locked and you must enter the
4- to 8-digit phone password each time the phone is switched on.
Once the correct password is entered, you can use the phone until you switch it off.
The following options are available:
- Disable : you are not asked to enter the phone password when you switch on the
phone.
- Enable : you are required to enter the phone password when you switch on the
phone.
Change password
The Change password feature allows you to change your current phone password to
a new one. You must enter the current password before you can specify a new one.
Once you enter a new password, you are asked to confirm the change by entering
the password again.
