Defining PIN code settings
• To define PIN code settings, select Security →
Telephone 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 restriction password
• To change the password used for restricting voice,
fax, and data calls, select Security → Telephone
security, and select the Call restriction page. Select
the Restriction password field, and press Change.
Enter the current code, and then the new code
twice. The restriction 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 theOther page. They are
used by some services, such as banking, for checking
the validity of other certificates.
