Volume control

Separate knobs on the control module control the volume for each

separate earcup (Figure 18).

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.
