As with any complex electronic device, it is possible for thisheadset to fail during operation. Symptoms of failure may include loud tones,distortion, and loss of communications signal in the headset when used in theAcoustic Noise Cancelling mode.Note: The headset includes redundant circuitry to reduce the effects of such failuresand to allow for continued use of the headset in the passive noise reducing mode.In passive noise reducing mode, the volume controls on the control module willautomatically be set to maximum volume. If additional volume control isneeded, you can use the intercom or radio volume control.Acoustic Noise Cancelling mode is active when the headset control module ispowered on (power indicator is lit). The headset is in the passive mode whenthe power is off (power indicator is not lit). See “Control module variations” onpage 6.If your headset is aircraft powered, connect the headset to the aircraft powersources only as described in “Connecting the headset to the aircraft” onpage 11. The headset will not operate properly if used with any battery sourceother than the Bose A20 Aviation Headset control module.1

Noise reduction and communications performance are reduced withAcoustic Noise Cancelling mode turned off.Volume controlMake sure your aircraft communications system volume control is easilyaccessible. This control affects the strength of the communications signalcoming into the headset.As pilot in command, you must be sure you can understand criticalcommunications even with Acoustic Noise Cancelling mode turned off. In thiscase, you may need to turn up the aircraft communications system volume.Avoid setting the volume controls at levels high enough to impair your hearingduring extended periods of headset use.Recognizing aircraft soundsWith the headset’s active and passive noise reduction, typical aircraft sounds(such as engines, propellers, warning alarms, and other sound sources) maynot sound familiar. We strongly advise you to make sure you can hear andrecognize these sounds when using the Bose A20 Aviation Headset whileoperating any aircraft.Using audio sourcesWhen listening to in-flight entertainment, or a portable audio source through aBose A20 Aviation Headset, be sure to limit the volume to safe levels that donot interfere with your ability to hear informational sounds and warning alarms,such as stall warnings or gear up, while piloting.2
