How use of the headset affects hearing safety

Other cautions

4
The headset is intended for use with ANR turned on. Noise reduction
and communications performance are reduced with ANR turned off.

Volume control

Make sure your aircraft communications system volume control is
easily accessible. This control affects the strength of the communi-
cations signal coming into the headset, whether ANR is on or off.
As pilot in command, you must be sure you can understand critical
communications even with ANR 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.

Listening to the sounds of your aircraft

With the headset's active and passive noise reduction, typical aircraft
sounds (from 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
Aviation Headset

Using entertainment audio sources

When listening to in-flight entertainment or a home audio source
through a Bose 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.
