Flipping away one earcup  
The headset features a “flip-away” earcup for single-  
sided listening.  
Adjusting the volume directly on the audio system  
Connect the headset to the corresponding sockets of your  
audio system. Adjust the volume directly on the audio  
system.  
Hearing damage due to high volumes!  
CAUTION!  
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 sounds such as  
warning alarms.

Adjusting the volume via the slide volume controls  
(HME 46-V-K only)  
The two slide volume controls and allow you to  
adjust the volume for the left and right channel  
separately.  
Changing the left and right audio channel  
(HME 46-V-K only)  
The position “R” or “L” of the BOOM switch »  
corresponds to the position of the microphone on the left  
or right side of the mouth. When the microphone boom is  
rotated to permit left or right side microphone  
orientation, the BOOM switch allows you to correctly  
assign the audio channels (L/R) to the appropriate  
headphone sides. This enables the correct orientation of  
the volume controls and any audio signals. To move the  
BOOM switch, use a pointed tool.  
7
 
Adjusting the microphone sensitivity  
The microphone sensitivity has been factory pre-set to  
80 mV/Pa as per RTCA DO-214. You can change the  
microphone sensitivity by turning a small screwdriver in  
the direction of the arrow.

Care and maintenance  
Cleaning the headset  
Use a soft, slightly damp cloth to clean the headset from  
time to time. If the headset is very dirty, use a cloth  
dampened with mild, soapy water.  
Danger of short-circuit due to the ingress of  
water!  
CAUTION!  
Water entering the housing of the headset  
can cause a short-circuit and damage the  
electronics.  
Use only a slightly damp cloth to clean the  
headset. Do not use any solvents or cleansing  
agents.  
Replacing the earpads  
For reasons of hygiene, the black earpads should be  
replaced from time to time. Grasp the edge of the foam  
earpad behind the earcup as shown and peel it up and  
away from the earcup. Slide the new earpad onto the  
earcup. Repeat for the other earcup.

incorrect operating voltage), wear and tear, force majeure and defects  
which were known at the time of purchase are excluded from guarantee
