Again" when PTT pressed

Cannot see any Private contacts
in the Contact List
Check to see if the Private contact is set to Group Only. A Private contact that is set
to Group Only will not see Private contacts in the Contact List.
Cannot add maximum number of
PrivateGroups
To increase communications security, PrivateGroups reuse Private IDs in the
system. Therefore, the number of PrivateGroups allowed cannot be more than the
number of Private contacts in the system. Adding more Private contacts will allow
more PrivateGroups to be entered, until the maximum is reached.
Display shows “ID Not Available”
when trying to add a
PrivateGroup
No ID is available since all have already been used to create a
PrivateGroup. Adding more Private contacts allows more additional
PrivateGroups, until the maximum amount.
