• Decrease the risk of viruses or other malicious software and be sure of the
authenticity of software when downloading and installing software.
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.
CHANGE THE TRUST SETTINGS OF AN AUTHORITY CERTIFICATE
Scroll to an authority certificate, and select Options > Trust settings. Depending
on the certificate, a list of the applications that can use the selected certificate is
shown. For example:
• Internet—The certificate can certify e-mail and imaging servers.
• App. installation—The certificate can certify the origin of new software.
• CALL RESTRICTION (NETWORK SERVICE)
Select Menu > Settings > Call restriction.
Call restriction allows you to restrict outgoing and incoming calls
with your phone. For this function, you need the restriction
password, which you can obtain from your service provider.
Select Options, and choose one of the following:
Activate—Request the network to set call restriction on.
Cancel—Set the selected call restriction off.
Check status—Check whether the calls are blocked.
Edit restr. passw.—Change the restriction password.
Cancel all restrict.—Cancel all active call restrictions.
You cannot restrict incoming calls while call forwarding or fixed dialing is active. See
"Call forwarding (network service)" on page 21. See also “Security” on page 63. When
calls are restricted, calls still may be possible to certain official emergency numbers.
