Separate knobs on the control module control the volume for each
separate earcup (

Overall headset volume control requires adjustments at both the air-
craft intercom or radio and at the headset control module. Even at its
lowest setting, neither knob on the control module can completely
turn off the volume.
CAUTION: Avoid setting the volume levels too high. Exposure to
loud sounds may cause hearing damage.
