ONFIGURATION
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 option, the channel settings do not
change.
5 Optionally enable the Refresh Channels on Add/Remove check box. This
refreshes each channel as you add or remove it.
6 To remove a channel from the Member List, select the channel in the
Member List and click >>.
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 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 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, 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.

3 Click Remove. A prompt appears asking if you want to remove the group.
