Headset Instructions
The S-68 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.
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.
When you rst connect the headset, turn the volume control on the headset up
to the full clockwise position, 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 necessary.

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 thoroughly
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.
