Using the headset
Switching NoiseGard™ on/off
The NoiseGard™ ON/OFF switch allows you to switch the NoiseGard™ active noise compensation on or off. With NoiseGard™ switched off, the headset can be used as a conventional headset.
Set the NoiseGard™ ON/OFF switch to the desired position:
ON: NoiseGard™ is switched on.
The LED lights up, indicating the battery charge status (see page 12) or power supply via the aircraft DC power supply system.
OFF: NoiseGard™ is switched off. The LED is off.
Adjusting the volume
The two slide volume controls allow you to adjust the volume for the left and right channel separately.
CAUTION! Hearing damage due to high volumes!
This headset is capable of producing high sound pressure levels. Higher volumes or longer durations can damage your hearing!
Set the volume to a medium level. Make sure that you can hear critical environmental sounds and warning alarms.
Use the two volume controls to adjust the desired volume.
