ically direct the transmission to the originat-
ing unit.
The "MSG" status flag will remain flashing
even after the individual call time-out period
expires. Press the SPC button (SPecial Call)
to call the originating unit back. The origina-
tor's ID or name will be displayed. Follow the
procedures for sending a special call.
ENCRYPTED MESSAGE - If the transmis-
sion being received is an encrypted trans-
mission and the selected group is
programmed for private operation and the
correct cryptographic key is loaded into the
radio, then the receiver will unsquelch, the
"PVT" status flag will flash and the private
message will be heard in the speaker. The
radio automatically switches between clear
or private operation when it is receiving on a
group or channel programmed for private
operation.
