The volume control is a rotary control that sets the volume of the audio heard
through the headset or loudspeaker. To reduce volume, crew member turns
control in a counter-clockwise direction and for increased volume, in a clockwise
direction. The color bands around the volume control indicate the following
volume levels, 85 dB (end of green), 95 dB (end of yellow), and 110 dB (end of
red). There are click stops at these positions to prevent inadvertent adjustment
due to vehicle or gun shock. Volume levels at the headset receiver must be
adjusted to the minimum levels required for operation. The volume control
should be adjusted from the minimum position in the green click stop zone, up to
a comfortable level. Prolonged excess volume will lead to hearing loss.
EXPOSURES TO RADIO SIGNALS IN THE FULL ON
POSITION BEYOND 45 SECONDS MAY CAUSE HEARING
LOSS. ANY PROLONGED EXPOSURE IN THE FULL ON
VOLUME CONTROL SETTING REQUIRES THE USE OF A
SINGLE HEARING PROTECTIVE DEVICE IN EACH EAR.
