8.18.4.3 Scanned Group Calls
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang
time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same
group was available in private and entered in the scan list, it can receive clear and private calls, provided
auto-select was programmed in the radio. The user can select transmitting on the scanned or selected
group. If a group is entered in the scan list more than once and under different modes, (clear, digital, or
private), then only the first occurrence of the group will be used.
