Read Before Use
General:
•
•
Read this technical manual completely before using the product.
This technical manual is also available at www.telex.com/aviation.
Health and Safety:
•
•
•
•
Always keep at least 4” (~10cm) between the ear cups and a
pacemaker or implanted defibrillator because this product
generates magnetic fields.
Keep away from children – product parts and accessories are a
choking hazard.
With ANR (Active Noise Reduction) active, typical aircraft sounds
may not sound the same as when not using the ANR. Before
operating in an aircraft, verify ANR is active and you can hear and
recognize sounds properly. Set the volume to a safe level that does
not diminish your hearing of alarms and warnings.
This headset is capable of producing sound pressure over
85dB(A). In many countries, this is the maximum legal level for
continuous noise exposure during the working day. Do not listen at
high volume levels for extended periods of time to prevent hearing
damage.
Preventing Damage and Malfunctions
•
•
•
Always keep the headset dry and do not expose it to extreme
temperatures to avoid corrosion or deformation.
Never attempt to repair a headset which is not operating correctly.
Contact the Telex dealer you purchased the headset through or
authorized repair facility.
Only replace parts of the headset whose replacement is described
within this manual. All other parts must be replaced by an
authorized repair facility.

Installation
Installation
To install the headset for use, do the following:
Step 1
Inspect the headset for signs of damage. Do not use the
headset if signs of damage are evident.
Step 2
Plug the headset into the aircraft console (see “Install the
Dual Plug Headset in an Aircraft” on page 14 or “Install the
Single Plug Headset in an Aircraft” on page 14).
Step 3
Adjust the headband (see, “Headband Adjustment and Sizing” on page 15).
Step 4
Adjust the ear cups (see, “Ear Cup Adjustment” on page 16
Step 5
Adjust the mic for proper use (see “Mic Placement” on
page 17).
Step 6
Verify ANR is active (see “ANR System” on page 21)
Step 7
Attach the clothing clip. Using the clothing clip reduces the
cord weight from the headset (see “Clothing Clip Assembly
and Attachment” on page 19).
NOTE:
If required, Volume Adjustment (see,“Headphone Volume
Adjustment” on page 23), and then repeat steps 1
through 7.
14 Installation
Airman 8
Install the Dual Plug Headset in an Aircraft
To install the dual plug headset in an aircraft, do the following:
1.
Insert the microphone plug (smaller plug) into the microphone
jack on the aircraft audio panel.
2.
Insert the headset plug (larger plug) into the headset jack on the
aircraft audio panel.
FIGURE 1.
Dual Plug Connection
For a detailed plug wiring diagram, see “Dual-Plug” on page 11.
Install the Single Plug Headset in an Aircraft
To install the Single plug headset in an aircraft, do the following:
>

Airman 8
Installation 15
Headband Adjustment and Sizing
The Airman 8 headset is designed to rest evenly on top of the head with each
ear cup sitting centered and flush on each ear. The headset should fit over the
head without pinching or gapping.
To adjust the headband size, do the following:
>
With the headset resting securely on the top of the head, slide the ear
cup up and down to center the ear cup over the ear.
NOTE: The headset works best when the headband pad is centered
on the head. Both sides of the headset should be slid evenly
for proper use.
FIGURE 3.
Headband Adjustment
16 Installation
Airman 8
Ear Cup Adjustment
To adjust the ear cup to fit correctly, do the following:
>
Swivel the ear cup left or right to position the ear cup flat on the
ear.
NOTE: Over time, repositioning the headset may be necessary for
comfort.
FIGURE 4.
Ear Cup Adjustment
IMPORTANT:
ANR performance may be diminished if ear cups are
improperly fitted to the ears.
Take care not to over-adjust the ear cups. Do not rotate
the ear cups more than 90° or damage to the headset
may occur.
Airman 8
Installation 17
Mic Placement
The headset ships with the boom positioned at the top of the headband.
Rotate the entire boom overhead to wear the microphone on either the right or
left side of the head.
CAUTION:
There are boom rotation stops on each side of the boom
rotation. The boom microphone is rotated upward to move to
the other side of the headset.
***Do not rotate past the built-in stops. Doing so will
damage the microphone***.
FIGURE 5.
Microphone Rotation
18 Installation
Airman 8
To properly place the mic, do the following:
1.
Rotate the boom to the side you want to use (left or right).
2.
Bend the boom to position the mic in from of the mouth.
NOTE: For best noise-cancelling quality, place the boom mic as
close to the mouth as possible and speak into the mic.
FIGURE 6.
Mic Placement
Microphone Gain Adjustment
The Microphone Gain has been factory-adjusted to the nominal level
required for normal radio operation.
IMPORTANT:
Under normal circumstances microphone gain does not
require adjustment. If needed, adjustment by an
authorized aviation technician is recommended. For
instructions on how to adjust the Microphone Gain, see
the Customer Maintenance Manual, located on
www.telex.com.
Airman 8
Installation 19
Clothing Clip Assembly and Attachment
Using the clothing clip reduces the cord weight from the headset. The clothing
clip comes attached to the cord and only needs to be adjusted up or down, for
best use.

Airman 8
CHAPTER 3
Using the Headset
ANR System
ANR (Active Noise Reduction) is used to reduce unwanted noise in the
headset from the surrounding environment. By reducing unwanted
background noise, the user is able to reduce the volume level of the intended
sounds providing more intelligible communications and long term hearing
safety. It uses power obtained from the aircraft through the boom microphone
connection (microphone bias voltage). The ANR system only works properly
when power is continuously received from the aircraft.
If power to the headset it lost, the failover system automatically reroutes audio
to the speaker so you can still hear communications, even though ANR isn’t
functioning properly.
22 Using the Headset
IMPORTANT:
FIGURE 1.
NOTE:
Airman 8
ANR is only available when power is applied to the
microphone. When conditions allow for boom
microphone power only during push-to-talk, it may be
preferred to keep the ANR power switch in the off
position. Leaving the ANR power switch in the on
position under these intermittent power conditions could
result in unintended ANR performance.
ANR Switch
The ANR switch ships in the on position and usually does not
need to be turned off.
To turn on ANR, do the following:
>
Move the ANR switch in the up position (located on earcup with
boom mic).
Airman 8
Using the Headset 23
Headphone Volume Adjustment
NOTE:
Not available on stereo version.
The Airman 8 has is equipped with a switch that allows you to adjust the
headset volume. When required, the user can increase or decrease
headphone volume level by moving the switch from normal to high.
NOTE:
The Airman 8 is shipped in the normal position and functions
properly with most avionics equipment. Under normal
circumstances, volume adjustment is not required.
CAUTION: This headset is capable of producing high SPLs (Sound Pressure
Levels). High volumes and/or long durations can damage hearing

Care & Maintenance
Recommended Maintenance Schedule
NOTE:
Ear cushions, headband pads, and microphone wind screens are
considered wear items. For proper headset performance, these
items need to be inspected and replaced at regular intervals. See
the maintenance schedule below for more information. Headset
performance diminishes if items are not replaced when
deterioration or damage is apparent.
