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.
