Safety tips

• When using a headset, typical aircraft sounds (for example, those from engines,

propellers, warning alarms, etc.) may sound different to you. Before operating any aircraft, make sure that, while wearing a headset, 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.

• Do not attempt to repair the headset yourself. If problems occur, contact your

Sennheiser agent for assistance.

• Only replace parts of the headset whose replacement is described in this manual. All

other parts of the headset must be replaced by your Sennheiser agent.

• Do not immerse the headset in water! For information on how to clean the headset,

contact your Sennheiser agent.
