Model S-68S
Headset Instructions
The S-68S series headsets are adjusted at the factory for immediate use with all
current standard radio systems in general aviation aircraft. Headsets equipped
with two plugs are the standard conguration. The headphone plug is the larger
diameter plug and should be inserted into the headphone jack (.250” standard
monaural jack). The mic plug is the smaller diameter plug and should be inserted
into the microphone jack (.206” standard microphone jack).
The headband is adjustable through a full range of motion, or the locking nuts
may be tightened to allow you to custom t the headset. Place the headset over
your head, adjust the slides up until minimum pressure is felt on the top of your
head. The headset is now properly adjusted. For maximum noise attenuation, the
clamping pressure has been set at the factory. Releasing the clamping pressure
by bending the headband is not advised, because loss of attenuation will result.
Note: If especially small (children) or large headbands are needed, they may be
ordered from Sigtronics.
The microphone boom is fully adjustable and will rotate 180 degrees for use on
the left or right side of the head. Make sure you are speaking into the side of the
mic labeled “Talk” or substantial loss of gain will occur. Microphone placement
should be at the corner of the mouth, approximately ” from the lips.
When you rst connect the headset, turn the volume controls on the headset to
maximum ( full clockwise on mic side, counterclockwise on pot side ), then adjust
the listening volume with the audio control of either your radio or intercom as
appropriate. Passengers should also turn their individual headset volumes up
fully. Doing this allows for a full range of adjustment for each passenger, since
those with the most acute hearing can turn their headset volume down, if neces-
sary.

The headset is equipped with a stereo / monaural switch on the non-mic side ear
cup. For monaural sound or aircraft with only monaural jacks, move the switch to
the monaural position. In aircraft equipped for stereo audio, move the switch to
the stereo position.
The headset parts may be cleaned with mild soap and water using a soft cloth.
Then dry immediately. Caution: Do Not immerse any part of the headset in
water or any other liquid. Be especially careful not to allow the microphone to
become wet! Exposure to moisture may cause internal corrosion and failure and
will void your manufacturers warranty.
Cleaning will help the headset maintain its “like new” condition for many years.
WINDSCREEN
The microphone windscreen will reduce annoying wind noise and breath pops
picked up by headset microphones. It also protects the microphone element
from dirt and moisture. The windscreen should be washed regularly to maintain
hygiene and avoid clogging. Wash in warm water and mild soap. Rinse thor-
oughly and make sure it is completely dry before putting it back on.
To remove the windscreen, carefully grasp the windscreen lightly along its entire
length and remove from the microphone element being careful not to twist the
element itself.
Put the windscreen on the microphone by gently pulling from the open end. Do
not pull it so tightly that it stretches against the end of the microphone.
WARRANTY
Your headset is covered by a limited ve-year parts and labor warranty. Please
see the enclosed warranty card for details.
You may refer to the parts list on the reverse side, if you choose to replace parts
yourself. The parts list describes parts for this particular headset only. Parts lists
for other models are available on our Web Site or can be obtained by contacting
Sigtronics Corporation.
