Important safety instructions

yPlease read these instructions carefully and completely

before using the headset.

yMake these instructions easily accessible to all users at all times. Always include these instructions when passing the headset on to third parties.

yDuring flight operation, do not use the headset for telephone calls.

yWith the NoiseGard 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 NoiseGard 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.

yThe 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!

yNever repair or attempt to repair a defective headset yourself. Contact your Sennheiser agent or the Sennheiser Service Department.

yOnly replace those parts of the headset whose replacement is described in this manual. All other parts of the headset must be replaced by your Sennheiser agent.

yProtect the headset from humidity. Use only a slightly damp cloth to clean the headset. For information on how to clean the headset, contact your Sennheiser agent.
