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 54.

- Be aware of sound differences 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 affects the strength of the communications signal coming into the headset. Make sure you can understand critical communications even with Acoustic Noise Cancelling mode turned off. 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 different results. Battery life may differ 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.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.

FIT THE HEADBAND

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

1. Locate the left Ⓛ and right ® 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.

1. Test the headset before flight.

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 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

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.

Cable clips

Squeeze the narrow end of the clip to open. Press the side button to release and reposition the clip along the cable.

POWER ON

Press the Power button ⏻.

ANC HIGH MED LOW

The Power light glows amber then blinks according to the battery level.

See "Power light" on page 36.

NOTE: The first time you power on your headset, noise cancellation is fully enabled.

See "Acoustic Noise Cancelling" on page 23.

POWER OFF

Press and hold ⏻ until the Power light glows amber, then release.

NOTE: When powered off, the headset provides passive audio communications.

Acoustic Noise Cancelling reduces unwanted noise, providing a clearer, more lifelike audio performance. You can choose your noise cancellation level based on your listening preferences and environment.

NOTE: When you receive a call, the headset remains at the current noise cancellation level.

ACOUSTIC NOISE CANCELLING (ANC) SWITCH

Sets the noise cancellation level.

ANC HIGH MED LOW

FUNCTION POSITION DESCRIPTION

HIGH		Maximum quiet and noise cancellation across the entire spectrum. Best signal-to-noise ratio for radio and intercom communications in loud aircraft.
MED		Consistent noise reduction across a wide range of frequencies. Best for clear and comfortable noise cancellation in typical jet aircraft.
LOW		Best for improved interpersonal communication outside of the intercom in quieter environments.

TAP CONTROL FOR TALK-THROUGH COMMUNICATION

When you need to focus on interpersonal communication coming from a specific direction, you can automatically set noise cancellation to LOW in one earcup.

NOTES:

• By default, the TAP CONTROL operation switch is set to OFF.
• Tap Control is available only when the Acoustic Noise Cancelling (ANC) switch is in the HIGH or MED position.

• Tap Control is disabled during extreme levels of ambient noise to ensure proper noise reduction performance and intercom communication quality. However, you can still set the noise cancellation level to LOW in both earcups using the Acoustic Noise Cancelling (ANC) switch (see page 23).

• Make sure the Acoustic Noise Cancelling (ANC) switch is in the HIGH or MED position.

ANC HIGH MED LOW
