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.
