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 this guide
Please read this owner’s guide carefully. Save this guide for future reference and make it easily accessible for passengers and third
parties who use the headset.
• 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 31.
• 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.
• Be aware of sound differences while wearing the headset.
With the headset’s active and passive noise reduction, typical aircraft sounds (such as from engines, propellers, and stall or gear
up warnings) will not sound familiar on your first few flights. Such important sounds may be quieter than you are used to. You are
responsible for making sure that you can hear, notice and recognize these sounds when using the headset while operating any
aircraft.
• 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.
• Do not make phone calls while piloting.
During flight operations, do not use the headset for telephone calls.
• Make sure your aircraft communications system volume control is easily accessible.
Make sure you can understand critical communications even with Acoustic Noise Cancelling turned off. We recommend that you
set the audio system volume so that you can understand radio communications in passive mode, in full aircraft noise, then use
the control module’s volume controls to set a comfortable level with Noise Cancelling on. In passive mode, the control module will
automatically switch to maximum volume. If your headset is aircraft powered, connect the headset to the aircraft power sources
only as described in “Connecting the headset to the aircraft” on page 14.
• Make sure portable devices do not interfere with the aircraft’s navigation and communication systems.
It is a 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 Bose
®
A20
®
Aviation Headset.
• Make sure AUX source volume is turned up.
If the AUX source audio volume is set at a low level, it may be below the detectable threshold or may cut in and out.
• 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.
Important Safety Information

• Use only AA alkaline batteries.
Replace the batteries only with AA alkaline batteries (IEC LR06). There is a danger of explosion if batteries are incorrectly
replaced with any other battery chemistries. Batteries may cause a fire or chemical burn if mishandled. Do not recharge,
disassemble, heat, or incinerate batteries. Dispose of used batteries properly, following any local regulations. The headset will not
operate properly if used with any battery source other than the Bose A20 Aviation Headset control module.
• Keep batteries out of reach of children.
• Do not repair the headset yourself.
Do not attempt to remove, replace, or repair the protective inner screen on the inside of the earcup, which is critical to the
headset’s performance. If screen replacement or other repair seems necessary, contact Bose Technical Support. See “Contact
information” on page 42. If the screen gets wet or any foreign objects become lodged on or adjacent to it, follow the instructions
in “Headset Care and Maintenance” on page 27.
• Keep the earcup free of debris.
Proper headset operation requires that the headset TriPort
®
and microphone openings located on the outside of each earcup are
kept free of debris to ensure clear communications. See “Cleaning the headset” on page 27 for cleaning instructions.
• DON’T immerse the headset or any parts in water or any other liquid. See “Cleaning” for cleaning instructions.
Contains small parts which may be a choking hazard. Not suitable for children under age 3.
This product contains magnetic material. Consult your physician on whether this might affect your implantable
medical device.
• Do NOT expose this product to dripping or splashing, and do not place objects filled with liquids, such as vases, on or near
the product.
• Do NOT make unauthorized alterations to this product.
• Do not expose products containing batteries to excessive heat (e.g. from storage in direct sunlight, fire or the like).
