Note: If the aircraft already has pilot headset jacks, the location
can be used for intercom with the following changes. The mic
jack must be re-wired as follows:
1. Remove any existing wires from the tip, ring, and barrel connec-
tions.
2. Connect the intercom white/black wire to the ring terminal.
3. Connect one end of a wire to the barrel terminal of the mic jack
and connect the other end to Point “A”.
4. Install insulating washers as necessary if the barrel of the mic
jack is mounted in metal.
For the headphone jack, replace the mono headphone jack with
the stereo headphone jack. Connect the green wire (P2 pin 1) to
the tip connection. Connect the white/green wire (P2 pin 7) to the
ring connection.
WIRING INSTRUCTIONS
Connections should be made as shown in Figure 4 and indicated
in Tables 1 and 2. If longer wire lengths are required, use a good
quality hook-up wire - 22 gauge or larger. Although not necessary,
shielded audio wire can be used if desired. This can simplify the
wiring process.
