Model S-8H

Headset Instructions

The S-8H series headset is adjusted at the factory for immediate use with all current

standard radio systems in general aviation aircraft. The S-8H helicopter headset is

equipped with a single coiled cord and a U-174U plug.

The head strap is adjustable so you may custom t the headset. Place the headset

over your head and adjust the strap until minimum pressure is felt on the top of

your head. For maximum noise attenuation, the clamping pressure of the head-

band has been set at the factory. Releasing the clamping pressure by bending the

headband is not advised, because loss of attenuation will result.

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. If applicable, crew mem-

bers 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.
