4.0 Modular Flexible Design – Comm-Cord & Microphone Boom
The PA-1779T’s modularity includes some unique features. We have designed the headset to be modular
with the introduction of a detachable comm-cord and microphone boom. This modularity makes the headset
“field repairable”. Pilots can use the headset with or without comm-cord when they are doing their preflight
check. They can have different comm-cords for different uses such as helicopter or with 2-way radios,
simply by purchasing the appropriate comm-cord. Industrial users can wear a modified version with or
without a microphone and protect their hearing as well as have the flexibility to walk around without worrying
about a power source. The user can adjust the microphone boom from left to right by plugging into the 3.5
mm jack (small washer) on either side of the left or right ear cup. The larger jack (large washer) located
under the smaller jack on the boom side of the headset is reserved for plugging in your cell phone or music
input source (IPOD
® MP3 ® or CD player).
The microphone boom can be totally removed by fully extending the headband to its largest size so
approximately only 3/4 ” of the headband is passing through the rubber bushing located in the center of the
ear cup. Then grasp the tip of the headband and slowly pull/twist the headband through the rubber bushing.
To reattach, line up the molded rubber pieces of headband and snap the rubber molded piece back onto the
pivot.
4.1 Auto Shut-Off Circuitry
Your new PA-1779T comes equipped with our new Auto Shut-Off proprietary circuitry. The ANR will shut-off
automatically when the unit is unplugged from the aircraft or the master avionics switch is turned off. This
will conserve your battery’s life. The headset will automatically turn on when the unit is plugged into a live
intercom system when the white On/Off button is in the “On” position. Should you want to turn off the
headset while you are using the unit in an aircraft, simply press the On/Off button.
If you would like to bypass the Auto Shut-Off feature and use the headset as an ANR hearing protector,
there is an accessory available – the ANR/Cell Phone Energizer Plug. It can be purchased direct from Pilot
Communications USA at 1-888-GO-PILOT or www.pilot-usa.com
4.2 Testing Your ANR System
In order to test your ANR headset, it must be plugged into the aircraft with a live intercom with the white
On/Off button in the “On” position. The LED light will become illuminated when the ANR system is on. This
will let you properly test all functions of the ANR system. If you are not plugged into a live intercom or the
white On/Off button is in the “Off” position, the ANR system will not be activated but the headset will work as
a passive headset.
4.3 Cell/Satellite Phone Capability
Located on the boom side ear cup there are two 3.5 mm jacks. The upper jack is used for the microphone
cord and can also be used for charging the headset. The lower jack which has a larger nut around the jack,
is for cell phone or audio input. The headset comes with two cables marked “PHONE” and “AUDIO”. The
right angle (90
o ) plug on both cables should always plug into the headset. The straight plug will plug directly
into your cell phone or audio input source.
4.4 Sheepskin Head Pad
The headset is fitted with a breathable sheepskin head pad. This head pad virtually eliminates all complaints
of hot spots caused by non-breathable synthetic head pads used by other manufacturers. The natural head
pad combined with the single suspension of the headband assures a comfortable fit.
4.5 Silicone Gel Ear Seals
Your headset is fitted with our proprietary silicone gel ear seals. The new design eliminates 30% of the
weight of normal silicone ear seals and provides superior noise attenuation.
