Hearing safety
The headset is intended for use with the Acoustic Noise Cancelling
®
mode
turned on. Noise reduction and communications performance are reduced with
Acoustic Noise Cancelling mode turned off.
Volume control
Make sure your aircraft communications system volume control is easily
accessible. This control affects the strength of the communications signal
coming into the headset.
As pilot in command, you must be 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.
Avoid setting the volume controls at levels high enough to impair your hearing
during extended periods of headset use.
Recognizing aircraft sounds
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. We strongly advise you to make sure you can hear and
®
recognize these sounds when using the Bose
A20™ Aviation Headset while
operating any aircraft.
Using audio sources
When listening to in-flight entertainment, or a portable audio source through a
Bose A20 Aviation Headset, be sure to limit the 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.
