both the WHITE/GREEN and GREEN on to the TIP of the headphone
jack.
6. The Violet wire (J1 pin 12) is provided on the Sport 200 S for an optional
Push-to-intercom function. For wiring and additional instructions see
the “Sport 200 S PUSH-TO-INTERCOM INSTRUCTIONS” section on
page 4. Make sure any unused wires are properly insulated and kept
from shorting to any other wires or aircraft ground. Skip down to
the “INSTALLATION CHECK OUT AND ADJUSTMENT section on this
page.
INSTALLATION CHECK-OUT AND ADJUSTMENTS
After the unit is installed, again check that the Sport 200 S unit chassis,
jacks, and wiring harness are clear of all aircraft operating controls and
cause no interference with them. Next, to check out the Sport 200 S
unit installation, plug in all the headset mic and phone plugs into the
respective intercom jacks. Put on the pilots headset and position the
boom mic close to the mouth. Voice clarity is best when the mic is at
one side of the mouth and 1/4” from the lips.
To assure that the aircraft radios, pilots headset, and PTT switch are
connected and functioning properly, switch the Sport 200 S ON/OFF
switch to the off position. If applicable, set the aircraft audio panel to
“Headphone” position. Then turn on the aircraft radio(s) as usual, and
verify that the pilot can hear the radios and can transmit using his push-
to-transmit switch and headset. Aircraft radio(s) and audio panel should
operate exactly as they did before the Sport 200 S system was installed.
Aircraft radio reception should also be heard in the co-pilot headset.
There should be no intercom between headsets with the Sport 200 S
unit off. Next turn the Sport 200 S unit on”. Set the Sport 200 S volume
control to mid-position. Set Sport 200 S squelch control fully clockwise.
Verify that the Pilot and co-pilot can operate the aircraft radio(s). As
before, both headsets on the intercom will hear the aircraft radio(s).
Check that both headset positions can intercom.
It may be necessary at this time to adjust the Sport 200 S unit mic output
to the aircraft radios. A small adjustable potentiometer is provided inside
the unit for this purpose. It is accessible through a hole in the side of the
Sport 200 S chassis. It is marked “Mod. Adj.”, and can be adjusted with a
