Adjusting the microphone gain (not HMD 120)
According to JTSO approval C58a, the microphone output voltage is factory-preset to 400 mV/114
dB. If the microphone output voltage is too high or too low for your intercom system, it can be
readjusted on the microphone. To do so, use a small slotted screwdriver and turn the ‘Mic Gain
Adjustment’ screw (see illustration on the left) until you have reached the desired setting.
Folding up the headphones
For easy and space-saving transportation, the earcups can be folded up and tucked between the
headband.
̈ Unfold the headphones by grasping both earcups and pulling them down and away from the
headband.
