Safety requirements
y 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.
y Do not attempt to repair the headset yourself. If problems occur, contact your Sennheiser agent
for assistance.
y 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.
y Do not immerse the headset in water! For information on how to clean the headset, contact
your Sennheiser agent.
