Pro Tips
Always ensure the SH30-75B is fitting correctly by reviewing adjustments each
time you wear them, ear seals should be centered over the ears for best
performance.
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. If wearing glasses the use of
cotton ear seal covers can reduce this if experienced.
When using the power switch ensure your push down on the button of the switch
then selected to the desired position, this helps protect the switch and ensure
reliable operation
Position the microphone in front of your lips for maximum noise cancellation.
Set the 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.
It is suggested that the USB power supply is used at all times to ensure continued
operation of both the ANR and Bluetooth functions
