If a group or channel is not programmed for Private Mode operation,
PVT DIS will be displayed if an attempt is made to enable private
transmit mode. It is not possible to operate on this group/channel in
Private Mode.
If the radio does not have the correct encryption key loaded, NO KEY#
will be displayed and the call will not be transmitted.
3. Continue with standard transmission procedures. A Private Mode access
tone will be heard when the PTT button is pressed.
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 autoselect, 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 autoselect 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 in different modes (clear, digital,
private), only the first occurrence of the group will be used.
