the lower frequencies more than any other ANR headset on the market. Embedded in our ANR technology is an Enhanced Voice
Intelligibility (EVI) circuit. EVI enhances speech frequencies by 2 - 4 dB on all audio input. This unique combination of noise cancelin g
and speech enhancement gives Pilot USA¶s range of ANR headsets increased intelligibility and more performance.

PILOT PA-1761M | Military Headset ANR Headset
2 .0 Fitting Your Headset
Wearing your headset properly is paramount to achieving both comfort and the best performance from your new ANR headset. The
headset should be placed on your head and slowly pulled down so that each ear cup is properly positioned over each ear for maximum
noise attenuation.
The headband can be tightened or loosened by using the hand adjustable knurled knobs on the slides of the headband so that it fits
your head properly. It shou ld apply slight pressure on your head without being snug. You may need to make your final adjustments in
a high noise environment and with the ANR electronics turned on.
2. 1 Microphone Placement
Your headset comes with a fully flexible microphone boom and a noise canceling electret microphone. The boom can be rotated 360
degrees for left or right side use. Proper placement of the microphone is critical in order to achieve clear communications. The
microphone should be placed at the corner of your mout h approximately 1/4´away from the lips.
2. 2 Volume Control (On Comm -cord splitter)
The PA - 1761M is fitted with 2 individual volume controls, one each for right and left side of the headsets. The volume control is
located on one side of the triangular splitter on the comm - cord. The other side contains the mono/stereo selector. When adjusting the
volume control the pilot -in- command should adjust their volume control first with the audio system turned on and the ANR system
turned off. Then turn the ANR back on and adjust the individual sides of the headset.
2. 3 Mono/Stereo Selector (On Comm -cord splitter)
Your headset comes standard with a Mono/Stereo selector switch which is located on one side of the triangular comm - cor d splitter.
³M´indicates the mono position while ³S´indicates the stereo position. The volume control is on the reverse side. It should be noted
that if you are using a monaural intercom and your headset is set in the stereo position, you will only hea r through one speaker on your
headset. With a stereo intercom, you will hear true stereo in if the selector switch is set to the stereo mode position.
2. 4 Battery Box
The battery box has three other functions other than just powering your ANR headset. It contains the Power Button, has an LED
power indicator light, Power Jack and Battery Compartment
2.5 Power Button (On Battery Box)
The push button on the battery box is the On/Off switch for your ANR headset. To turn power on, press the button down, re -engaging
the button will turn the power off. When the ANR system is turned on the green LED light on the faceplate of the battery box will
illuminate.
2. 6 LED Light (On Battery Box)
The LED light indicates the power status of your ANR system. When the light is illuminated, the ANR system is turned on.
2. 7 Power Jack (On Battery Box)
The power cord from the headset plugs into the power jack on the face plate of the battery box
.
2.8 Battery Compartment (On Battery Box)
The ANR System is powered by one 9V alkaline battery. Battery life is estimated to be 25 - 35 hours depending on level of noise in the
environment. Battery life is also affected by age, and extreme temperatures (hot or cold). To change the battery, simply slide the
battery plate off of the battery box and insert the new battery. Reinstall the battery plate and you¶re ready to go.
2. 9 C ell/Satellite Phone Capable
Having the capability in an emergency of being able to place a cell phone call from your aircraft is one of the reasons PILOT has
installed a Cell/Satellite jack on the headset. Located on the non - boom side ear cup, a 2.5mm ja ck has been installed. It will work
with 90% of cell phones in the marketplace. An adapter may need to be purchased from your local electronics shop in order to
utilize this feature. The jack can also be used to plug in your music input source.

3. 0 Soft Headset Case
We provide you with a padded headset case to protect your ANR headset and to house your battery box, headset and comm - cord. You
should treat you headset like you would treat any othe r electronic product of value. Keep clean, and keep it out of extreme
temperatures.
3. 1 Taking Care of Your Headset
Treat your headset like you would treat your stereo and computer at home. To utilize the full life of your headset, keep it clean and
f ree of dirt and you will extend the headset¶s life giving you many years of flying pleasure.
Clean your headsets with non - alcohol wipes or a soft slightly cloth dampened with water and a mild soap. Never use alcohol . Plastic
parts dry out or fray when exposed to alcohol based products. Headband, ear cups, ear seals and cords can be lightly cleaned but one
should be careful around the microphone and speakers on the headset.
3. 2 Mic Windscreen
PILOT USA recommends periodical ly replacing the microphone windscreen if necessary. The foam microphone windscreen helps
eliminates the popping ³P´s and ³T´s and annoying breath puffs when you¶re communicating with the headset. The foam microphone
windscreen also helps protect the mic rophone from moisture and other elements that may cause damage to the electronics. You may
use mild soap and water to clean your foam windscreen. Place the foam windscreen in mild soapy water. Rinse and make sure the
windscreen is fully air dried before reattaching to the microphone.
3. 3 Ear Cushions
Ear seals also need periodic replacing. Depending on how much you fly, temperature (extreme heat or cold) also influences the life
span of your ear seals. We have several types of ear seals on our headset s. Generally, PVC, foam and silicone gel style ear seals can be
wiped off with mild soap and water. Do not s ubmerge the ear seals in water. All three types of our ear seals have vent holes and
water would enter the ear seal¶s vent holes ruining the ear s eal.
3. 4 Communication Cord
Take care of your communication cord. Wires in the cord can break if abused. Always disconnect them by disconnecting the plugs,
not by pulling the cords. Pulling on the cord, instead of the plugs is a major cause of headset repairs ± it causes wire breaks and static.
We recommend storing your headset in a headset case or flight bag and keeping the cords free of obstruction to reduce wear and tear
on your head
