Safety instructions
Please
read
these
instructions
carefully
and
completely before using the headset.
Make these instructions easily accessible to all users
at all times.
Always include these instructions when passing the
headset on to third parties.
During flight operation, do not use the headset for
telephone calls.
With the NoiseGardTM active 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.
The headset is capable of producing sound pressure
levels exceeding 85 dB(A). In many countries 85 dB(A)
is
the
maximum
legally
permissible
level
for
continuous noise exposure during the working day.
Exposure to sounds of higher volume levels or for
longer durations can permanently damage your
hearing!
Never repair or attempt to repair a defective headset
yourself. Contact your Sennheiser agent or the
Sennheiser Service Department.
