completely before using the product.
왘Always include this instruction manual when passing the
product on to third parties.
왘This instruction manual is also available on the Internet at
www.sennheiser-aviation.com or www.sennheiser.com.
Preventing health problems and accidents
왘Always maintain a distance of at least 3.94“ (10 cm)
between the ear cups and the cardiac pacemaker or
implanted defibrillator since the product generates
permanent magnetic fields.
왘Keep product, accessory and packaging parts out of reach
of children who could swallow smaller pieces.
왘Switch the product off after use to conserve battery
power. Remove the rechargeable batteries if the product
will not be used for extended periods of time.
왘If during flight operation you, as the pilot, operate your
connected device using the headset, this can limit your
attention. During flight operation, do not use the headset
for making phone calls or listening to music.
왘With the NoiseGardTM noise compensation switched on,
typical aircraft sounds (for example, those from engines,
propellers, warning alarms, etc.) may sound different to
you. Before operating any aircraft, make sure that, with

NoiseGardTM switched on, you can hear and recognize
these sounds. Set the volume to safe levels that do not
interfere with your ability to hear informational sounds
and warning alarms.
왘The product is capable of producing sound pressure
exceeding 85 dB(A). In many countries 85 dB(A) is the
maximum legally permissible level for continuous noise
exposure during the working day. Do not listen at high
volume levels for long periods of time to prevent hearing
damage.
