Model S-AR
Headset Instructions
The S-AR 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 configuration. The headphone plug is the larger
diameter plug and should be inserted into the headphone jack (.250” standard
stereo or monaural jack). The mic plug is the smaller diameter plug and should
be inserted into the microphone jack (.206” standard microphone jack). The
S-AR stereo headset has dual volume controls, a stereo headphone plug, and
a stereo-mono switch for operation with either stereo or monaural systems.
The headband is adjustable through a full range of adult sizes, or the locking nuts
may be tightened to allow you to custom fit 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 (youth size) or large headbands are needed, they may be
ordered from Sigtronics.
The microphone boom is fully adjustable and will rotate 180 degrees. For best
results use with the microphone on the left 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, approxi-
mately 1/4” from the lips. Sigtronics ultra-deep gel ear seals will provide for best
performance. Do not insert any material into the ear cups.
When you first connect the headset ,make sure the stereo / mono switch is in
the proper position (i.e. in the “MONO” position if plugged in a mono jack or in
the “STEREO” position if plugged into a stereo jack). With the S-AR power plug
securely fastened to the battery box power jack, push the power switch to the
“ON” position. Turn both volume controls on the headset up to maximum volume.
For the mic side volume control, maximum volume is full clockwise. For the switch
side volume control, maximum volume is full counter-clockwise. Adjust the lis-
tening volume with the audio control of either your radio or intercom as appro-
priate. 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.

Test the headset in the “ON” and “OFF” modes on the ramp prior to take off. If there is a
problem in the “ON” position then use in the “OFF” position. The S-AR is completely fail-
safe and will continue to work even if power to the headset is lost. If the power to the
headset is unstable, simply turn off power and use headset in the “OFF” position. The S-AR
performs best when using high quality Alkaline batteries. The life of these high quality bat-
teries should last 20 hours minimum. To guard against accidentally leaving the power on,
unplug the power cable from the power module when not in use. DO NOT ATTEMPT TO
POWER THE S-AR DIRECTLY FROM YOUR AIRCRAFT electrical system without using our
panel mount power system. This system will give clean stable power to the S-AR.
CLEANING
Headset parts may be cleaned with mild soap on a soft damp cloth. Then dry immediately.
CAUTION: Do NOT immerse any part of the headset in water or any other liquid. Be espe-
cially 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 mois-
ture. 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 it 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 three-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
