on the certificate, a list of the applications that can use the selected certificate is
shown. For example:
• Internet—The certificate is able to certify e-mail and imaging servers.

of the certificate and that the certificate really belongs to the listed owner.

• CALL RESTRICTION (NETWORK SERVICE)

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. Call restriction affects all calls, including data calls.
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 if the calls are blocked or not.
Edit restr. passw.—Change the restriction password.
Cancel all restrict.—Cancel all active call restrictions.
You cannot block incoming calls while call forwarding or fixed dialing is active.
See "Call forwarding (network service)" on page 23. See also "Security" on page 67.
When calls are blocked, calls still may be possible to the official emergency number
programmed into your phone.

• NETWORK

Select Menu > Settings > Network > Operator selection or
Cell info display.
Operator selection
Automatic—Set the phone to automatically search for and select one of the
cellular networks available in your area.

to the manually selected network is lost, the phone will sound an error tone and ask
you to select a network again. The selected network must have a roaming agreement
with your home network, that is, the operator whose SIM card is in your phone.
