Important Safety Instructions
WARNINGS/CAUTIONS
• Do NOT use the headphones with noise canceling mode at any time the inability to hear surrounding sounds may
present a danger to yourself or others, e.g., while riding a bicycle or walking in or near trac, a construction site or
railroad, etc.
• Keep batteries out of reach of children.
• Please dispose of used batteries properly, following any local regulations.
• Danger of explosion if batteries are incorrectly replaced.
• Batteries may cause a fire or chemical burn if mishandled. Do not recharge, disassemble, heat, or incinerate.
• When a replacement is needed, use only a AA (LR06) alkaline batteries.
Please read and save this guide
Please read this guide carefully. Save this guide for future reference and make it easily accessible for passengers and
third parties who use this headset.
• Switch to an alternate communications method in the event of a headset issue.
In the unlikely event of any headset issue or failure in the passive noise reducing mode, switch to an alternate
communications method and use standard cockpit resource management skills to minimize distractions.
• Use the headset at a moderate volume level.
To avoid hearing damage, use the headset at a comfortable, moderate volume level. Limit the headset volume to
safe levels that do not interfere with your ability to hear informational sounds and warning alarms, such as stall
warnings or gear up, while piloting.
• Turn the headset o if it emits any loud noise.
As with any complex electronic device, it is possible for this headset to fail during operation. Symptoms of failure,
which may include loud tones, distortion, feedback squeals and loss of communications signal in the headset, can
occur in either the Acoustic Noise Cancelling mode (turned on) or in the passive mode (turned o). If the headset
emits any loud noise and the related loss of communications in the Acoustic Noise Cancelling mode, turn o the
power switch. The headset will continue to provide communications in the passive noise-reducing mode. If the
problem persists, see “Troubleshooting” on page 47.
• Be aware of sound dierences while wearing the headset.
With the headset’s active and passive noise reduction, typical aircraft sounds (such as engines, propellers, warning
alarms, and other sound sources) may not sound familiar. Make sure you can hear and recognize these sounds when
using the headset while operating any aircraft.
• Do NOT make phone calls while piloting.
Do not use the headset for telephone calls during flight operations.
• Make sure your aircraft communications system volume control is easily accessible.
This control aects the strength of the communications signal coming into the headset. Make sure you can
understand critical communications even with Acoustic Noise Cancelling mode turned o. In this case, you may
need to turn up the aircraft communications system volume. In passive mode, the volume controls on the control
module will automatically be set to maximum volume. For additional volume control, use the intercom or radio
volume control. If your headset is aircraft powered, connect the headset to the aircraft power sources only as
described in “Aircraft Connectors” on page 29.

IMPORTANCE OF PROPER FIT
FIT THE HEADBAND
Proper fit is important both for comfort and optimal noise cancellation performance.
1. Using the left T and right U icons on the headband to orient the headset
properly, rotate the side pads into position.
2. Place the headset on your head.
3. Adjust the headband so the side pads rest above your ears.
IMPORTANCE OF PROPER FIT
15

ENG
CHOOSE THE CORRECT STAYHEAR+ TIPS
For optimal audio performance, it is important to choose the correct size
StayHear+ tip. Select the size that gives you the best comfort and fit in each ear.
To determine the best fit, you may need to try all three sizes. You may need a
dierent size for each ear.
NOTE: Without a properly fitting tip, the noise reduction and audio performance of
the headset will be degraded. To test the fit, try speaking aloud wearing the
headset while it’s powered o. Make a low-pitched “eee” sound. Your voice
should sound amplified and balanced in both ears, similar to when you plug
your ears with your fingers. If not, try another tip size.
Each StayHear+ tip and earbud is marked with either an L or an R. Be sure to attach
the left tip to the left earbud and the right tip to the right earbud.
FIT THE EARBUDS TO YOUR EAR
The StayHear+ tip allows the earbud to rest comfortably and securely in your ear.
The tip wing fits just under your ear ridge.
1. Insert the earbud so the StayHear+ tip rests gently in the opening of the
ear canal.
2. Tilt the earbud back and tuck the tip wing under the ear ridge until it is secure.
TIP: If the StayHear+ tips don’t fit securely, choose a dierent size.

CHANGE THE STAYHEAR+ TIPS
1. Holding the earbud, gently grasp the attached StayHear+ tip and peel it away from
the earbud.
CAUTION: To prevent tearing, grasp the StayHear+ tip by its base. Do NOT pull on
the tip wing.

IMPORTANCE OF PROPER FIT
ADJUST THE MICROPHONE
NOTE: By default, the reversible microphone ships from the factory attached to the
left side of the headset. If you want to move the microphone to the other side
of the headset, see “Microphone Placement” on page 25.
1. Grasp the microphone base, and adjust the boom so the microphone is level with
your mouth.
CAUTION: Microphone placement is important for clear communication.
It can rotate 300°. Do NOT force the microphone beyond the
intended rotation or damage could occur.
2. Position the microphone so it is 0.5" (12.7 mm) from your lips, and the white
surface on the base is facing your mouth.
NOTES:
• If necessary, twist the microphone base to rotate the microphone into position.
• The microphone should not be touching your lips.
3. Test the headset before flight.
IMPORTANCE OF PROPER FIT

ENG
IMPORTANCE OF PROPER FIT
CONDITIONS RELATED TO FIT
In very loud conditions, such as during takeo, you may experience a brief reduction
in noise cancellation as the headset compensates for a momentary pressure
change. If this continues when the sound level returns to normal, see “Acoustic Noise
Cancellation” on page 20. If it persists, see “Troubleshooting” on page 47.
A low rumbling sound or frequent, brief losses of noise cancellation may indicate
an improper fit or blocked earbud ports. See “Choose the correct StayHear+ tips” on
page 15 for information on proper fit or “Clean the headset” on page 41 for
instructions on removing blockages.
During a long flight, you may feel a slight pressure point, which can be relieved by
adjusting the headband position.
