y Please read these instructions carefully and completely before using the headset.

yMake these instructions easily accessible to all users at all times.

yAlways 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.
