Congratulations on your purchase of
the Bose' Aviation Headset.
Description
The Bose AviaUon Headset uses an ad­
viced combination of electfoacoustical
noise reduction circuitry ar>d a patented
cushioning system to significantly reduce
aircraft noise. The Bose Headset actively
reduces noise elements in addition to muffling
noise. The patented Clear Comfort“ cushions
require only slight pressure to provide high
passive noise attenuation. Asa result, this
Headset can be worn comfortably for
extended periods.
For proper operation, all Bose Aviation
Headsets must be connected toa Bose
Headset interface. The interface pov/ers the
Headset's active noise reducing electronics
and matches the Headset to the aircraft's
avionics.

ATTENTION: With the Headset's combina­
tion of both active and passive attenuation,
typical aircraft sounds (for example, those
from engines, propellers, warning alarms, and
other sound sources) may sound different
to you.
We strortgly recommend that you erasure
you can hear and recognize these sounds
vrtiite you are using the Bose Aviation
Headset white operating any aircraft
In addition, we are aware that in-flight entertain­
ment systems are availat^. Therefore, should
you choose to listen to this entertainment
through a Bose Headset while piloting, we
remind you. asa respor^bie pilot, to limit the
volume to safe levels so that rt does not
interfere with your ability to hear informa­
tional sounds, such as those emitted by
warning alarms.
For proper Headset fit
NOTE: The Headset should be worn with the
sloped surfaces of the earcups facing forward.
Follow these suggestions to achieve maximum
comfort and performance.
Adjust both sides of the headband equally to
provide a balanced force on your head. To
achieve a good seal, lightly grasp both
earcups and position them so that your ears
are completely inside the Clear Comfort“
cushions.
If you experience either a hiss or a lov/
rumbling sound, this may indicate an improper
fit. Extending the headband slightly should
correct this condition. Wearing hats or glasses
with thick temples may interfere and cause a
problem.
Final adjustment is best accomplished in a
noisy erwironmem with the Headset system
turned on. Then, reposition both earcups until
the Headset seems quietest.
