SEHT SH40-80 USER MANUAL Edition 3

Stereo/Mono switch
The controller has a stereo/mono switch which needs to be set according to your aircrafts
headset wiring configuration (most aircraft are wired for mono). The switch is inside the
battery bay. If this switch is incorrectly set you will lose sound in the right ear cup
(assuming the headset is worn with the microphone boom on the left)
Pro Tips
1. Always ensure the SH40-80 is fitting correctly by reviewing adjustments each time
you wear them, ear seals should be centered over the ears for best performance.
2. There may be a noise generated if the ears seals are not providing a good seal
around the ear, in this case you should adjust the ear cup and ear seal to make
sure the ears are covered and sealed correctly.
3. Position the microphone in front of your lips for maximum noise cancellation.
4. If you are connected by Bluetooth to a mobile phone you can receive and end
calls by pressing the phone button on the front of the controller. Double press of
the button will dial the last used number.
5. Set Mono/Stereo setting to match your aircrafts avionics. In most situations this
would be mono, if set to the incorrect setting audio will be lost in one ear.
