The HME 100, HME 105, HME 110, HME 120 and HMD 120 are pilot headsets with closed ear
protector headphones for use in helicopters, propeller and turboprop aircraft.
Safety requirements
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.
