Each member in the groups is identified by a nickname, which is shown as a caller 
identification. Group members can choose a nickname for themselves in each 
group.
Groups are registered with a URL address. One user registers the group URL in the 
network by joining the group session the first time.
There are three types of push to talk groups:
• Provisioned groups are closed groups that allow only selected participants 
provisioned by the service provider to join in the groups.
• Ad hoc groups are groups that the users can create. You can create your own 
group, and invite members to the group.
• Ad hoc pro groups are groups you can create from members in a provisioned 
group. For example, a business can have a closed group, plus separate groups 
created for certain business functions.
Adding a group
1. Press Menu, and select Push to talk, Add group, and Guided.
2. To set the security level for the group, select Open group or Secured group.
If you select Secured group, the phone automatically creates a scrambled part 
to the group address that the members cannot view when they receive the 
invitation to the group. Only the person who creates the secured group, can 
invite more members to the group.
3. Key in the name for the group, and press OK.
