Headset Instructions
The S-65H series headsets are adjusted at the factory for immediate use with all
standard general aviation radio systems utilizing the U174/U jack. Headsets are
equipped with a coiled cable and a single U174/U plug conguration.
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 360 degrees for use on
the left or right side of the head. The locking screw that secures the boom to the
ear cup is factory set to insure the correct tension. Turning it will not change the
tension, because the nut on the inside of the cup will turn as well. Microphone
placement should be at the corner of the mouth, approximately ¼” from the
lips. The exclusive thumbscrew on the mic boom may be used to assure proper
adjustment.
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, take out the screw that holds the microphone on the
boom and grasp the windscreen lightly along its entire length and slip it o.
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.
