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.

IMPORTANT SAFETY INSTRUCTIONS

ENG

• 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 54.

• Be aware of sound dierences 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 aects 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 34.

• Make sure portable devices do not interfere with the aircraft’s navigation and communication systems.

Reference FAA AC 91.21-1D, or later revision, for installation approval.

It is the pilot’s responsibility to ensure that portable devices do not interfere with the aircraft’s navigation and

communication systems, as well as to determine if the portable device is suitable for use with the headset.

• Use AA (LR06) batteries, alkaline preferred.

Alkaline batteries are recommended for best results. Other battery chemistries may yield dierent results. Battery

life may dier and battery life indication may not be accurate. Properly dispose of used batteries.

• Do NOT repair the headset yourself.

Contact the Bose organization in your country/region for speciﬁc care, return and shipping instructions.

Visit: global.Bose.comglobal.Bose.com

• Do not use the headset with a helmet or as part of a crash protection system.

The headset is not intended for such use, and has not been certiﬁed for crash protection. Dismantling, reassembly

or modiﬁcation of the headset, or any part, for use in a helmet or other crash protection system could result in

severe bodily injury and such unauthorized use will void the limited product warranty.

• Do NOT immerse the headset or any parts in water or any other liquid.

See “Clean the headset” on page 48 for cleaning instructions.

• Keep the earcup free of debris.

Proper headset operation requires that the headset acoustic and microphone openings located on the outside of

each earcup are kept free of debris to ensure clear communications. See “Clean the headset” on page 48 for

cleaning instructions.

IMPORTANCE OF PROPER FIT

FIT THE HEADBAND

Proper ﬁt is important both for comfort and optimal noise cancellation performance.

1. Locate the left T and right U icons inside the earcups to orient the

headset properly.

2. Place the headset on your head.

3. Adjust the headband so the ear cushions completely cover your ears.

NOTE: For best performance, make sure the ear cushions ﬁt securely around your

ears so they create a seal.

IMPORTANCE OF PROPER FIT

ENG

ADJUST THE MICROPHONE

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.

The microphone boom can rotate 160°. Do NOT force it beyond

the intended rotation or damage could occur.

IMPORTANCE OF PROPER FIT

ENG

2. Make sure the microphone is 0.5" (12.7 mm) from your lips.

NOTE: The microphone should not be touching your lips.

0.5"

12.7 mm

3. Make sure the white dot on the microphone base faces your mouth.

NOTE: If needed, twist the microphone base.

4. 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

Cancelling” on page 23. If it persists, see “Troubleshooting” on page 54.

A low rumbling sound or frequent, brief losses of noise cancellation may indicate

an improper ﬁt or blocked earcup openings. See “Clean the headset” on page 48

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 THE CABLE AND CONTROL MODULE
