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 traffic, 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 off 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 off). If the headset emits any loud noise and the related loss of communications in the Acoustic Noise Cancelling mode, turn off the power switch. The headset will continue to provide communications in the passive noise-reducing mode. If the problem persists, see Troubleshooting on page 48.

Be aware of sound differences while wearing the headset. With the headsets 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.

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

1 6 | E N G

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 different 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 its powered off. 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 theStayHear+ 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 dont fit securely, choose a different size.

IMPORTANCE OF PROPER FIT

1 7 | E N G

Single earbud use When you want to use the headset with one earbud, you can stow the other earbud using the earbud storage hook on the back of the side pad.

Earbud storage hook

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.

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 26.

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

1 9 | E N G

CONDITIONS RELATED TO FIT In very loud conditions, such as during takeoff, 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 21. If it persists, see Troubleshooting on page 48.

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 16 for information on proper fit or Clean the headset on page 42 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.

SECURE CLOTHING CLIP AND CONTROL MODULE HOLDER The cable clips and control module holder secure the cable and control module to your clothing, a safety harness, sun visor rail, or aircraft headset hook for quick and easy access.
