Adjusting The Microphone Gain; Attaching The Cable Clip; Folding Up The Headphones - Sennheiser NoiseGard HMDC 322 Instructions For Use Manual

Mic Gain Adjustment

Adjusting the microphone gain

According to JTSO approval C58a, the microphone output voltage has to be factory-
preset to 400 mV. If this output voltage is too high or too low for your intercom system,
it can easily be re-adjusted 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 reach the
desired setting.

Attaching the cable clip

The headphone cable can be fixed by means of the cable clip. Guide the headphone cable
through the metal cable clip as shown in the illustration on the left. Attach the cable clip
to your clothing and then loop the cable through the clip so that the headphone cable
doesn't disturb you.

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.
