Closed user group
A closed user group is a network service that allows you to specify a group of people
you can call and who can call you. Contact your service provider for more information
about using this feature.
To enable or disable a closed user group:
1. From the Home screen, select Menu > Settings > Security > Closed user
group.
2. Select an option from the following:
• On - to enable the closed user group.
• Off - to disable the closed user group.
• Default - to specify that the people included in the group, which you have
agreed with the service provider, can call you and you can call them.
3. If you are enabling a closed user group, enter the group number when prompted,
then select OK. A confirmation message is displayed.
Security code
The security code helps protect your Vertu phone from unauthorised use. You will
need to enter this security code before you can do the following:
• Switch on the phone when a new SIM card is inserted (if you have set up security).
• Delete all contacts.
• Clear the call timers.
• Restore the workshop settings.
• Change the security level.
• Change the security code.
The first time you access a feature that requires the security code, you will be
prompted to create the security code.
To create the security code:
1. From the Home screen, select Menu > Settings > Security > Access codes >
Create security code.
2. When prompted, enter the required security code (between 5 - 10 digits long),
then select OK.
3. Enter the security code again for verification, then select OK. A confirmation
message is displayed.
Security level
The security level feature allows you to specify when you are required to enter the
security code.
To change the security level:
1. From the Home screen, select Menu > Settings > Security > Security level.
2. Select an option from the following:
• None - to disable the security code and allow any SIM card to be used in the
phone.
• Memory - to allow any SIM card to be used in the phone, but require entry of
the security code to access your Vertu phone’s directory after a different SIM
card has been inserted.
NOTE: Closed user groups are only available if they are supported by your
service provider.
NOTE: When outgoing calls are limited to closed user groups, calls may be
possible to the emergency numbers programmed in your Vertu phone, for
example 000, 08, 110, 112, 118, 119, 911 and 999, or other official
emergency numbers.
NOTE: Make a note of the security code, and ensure you keep it secret and
in a safe place.
NOTE: If you enter an incorrect security code five times in succession, your
Vertu phone will not accept the correct security code for the next five
minutes. Within that five minutes, your Vertu phone will show an error when
you attempt to enter the security code, even if it is correct.
