Behind the AUX/MIC connector there is a strapping area which looks like an IC-socket. There
are two rows with 9 holes. The row next to the AUX/MIC connector is connected to the
connector. The strapping is done by connecting the red strap wires, supplied with the RRC,
between the holes according to the description for the radio (see radio chapter). Normally the
same strapping should be done in both Control-RRC and Radio-RRC. (The picture shows the
strapping for IC-706). Attention! The strapping wires should NOT be soldered. Just
push them into the socket. The mechanical friction is enough to get connection.

Control-RRC only: JMP-1 is placed behind the TTL connector. With the strap in place a DC
voltage is feed to the microphone element. All ICOM microphones should be DC-feed.
Dynamic microphones like the ones used by Kenwood should not be DC-feed. HEIL
microphones should not be DC-feed either.
