With the NoiseGard™ active noise compensation turned on, typical aircraft sounds
(for example, those from engines, propellers, warning alarms, etc.) may sound
different to you. Before operating any aircraft, make sure that, with NoiseGard™
turned on, you can hear and recognize these
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.
