Defining PIN code settings
To define PIN code settings, select Security > Device
security, and select the PIN codes page.
Define the following:
• PIN code request — If you set this option to On, the PIN
code is requested each time the phone is switched on.
Note that this setting cannot be changed if the phone
is switched off or if there is no valid SIM card inserted.
Note also that some SIM cards do not allow you to turn
off the PIN code request.
• PIN code — Press Change to change the PIN code. The
PIN code must be 4 to 8 digits long. Changing the PIN
code requires that PIN code request is selected, the
device is on, and that there is a valid SIM card inserted.
• PIN2 code — Press Change to change the PIN2 code.
The PIN2 code must be 4 to 8 digits long. The PIN2 code
is required to access some functions, such as the fixed
dialing settings, which must be supported by your SIM
card.
Changing the barring password
To change the password used for barring voice, fax, and
data calls, select Security > Device security, and select the
Call barring page. Select the Barring password field, and
press Change. Enter the current code, and then the new
code twice. The barring password must be four digits
long.
Certificate manager
Important: Note that even if the use of certificates
makes the risks involved in remote connections and
software installation considerably smaller, they must be
used correctly in order to benefit from increased security.
The existence of a certificate does not offer any protection
by itself; the certificate manager must contain correct,
authentic, or trusted certificates for increased security to
be available. Certificates have a restricted lifetime. If
Expired certificate or Certificate not valid yet is shown
even if the certificate should be valid, check that the
current date and time in your device are correct.
Before changing any certificate settings, you must make
sure that you really trust the owner of the certificate and
that the certificate really belongs to the listed owner.
Digital certificates may be used for:
• connecting to an online banking service or another site
or remote server to transfer confidential information
• reducing the risk of viruses or other malicious
software, and checking the authenticity of software
when downloading and installing it
Managing certificates
Personal certificates are certificates that are issued to you.
They are listed on the User page.
Authority certificates are on the Other page. They are used
by some services, such as banking, for checking the
validity of other certificates.
To add certificates, select Security > Certificate
manager. Press Add to add a new certificate. You can then
