3 Click Membership. The Manage Group Membership dialog box appears.
4 To add a channel to the Member List, select the channel in the Non
Member List and click <<.
If you select the Copy Group Settings to Channels check box, the system
copies the settings of the selected group to each channel you add or
remove. If you do not select this check box, the channel settings are not
changed.
5 Optionally enable the Refresh Channels on Add/Remove check box. This
refreshes each channel as you add or remove it.
You cannot move a channel from the Member List to the Non-Member
List.
Each channel must belong to a group. A channel can belong to only one
group at a time. You cannot move a channel from the members list to the
non-members list of a group unless the system can assign the channel to
another group. If a channel has never been a member of another group,
the system cannot determine a group to which it can move the channel.
Therefore, it cannot remove the channel from the member list. If a
channel has been a member of another group in the past, the system
moves the channel to the group of which the channel was most recently
a member.
Example: By default, the system creates two groups, Group 1 and Group
2, and places all channels in Group 1. If you try to move a channel to the
non-member list of Group 1, the operation fails. If you select Group 2,
click Membership, move a channel from the non-member list to the
member list, and then move the same channel back to the non-member
list, the operation succeeds because the channel was previously a
member of Group 1. If you then view the Group 1 membership list, it
contains the channel you just removed from Group 2.
