Model S-68H

Headset Instructions

The S-68H 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 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 ¼” from the lips.

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.
