VOLUME CONTROL
The volume control is a rotary control that sets the volume of the audio heard
through the headset or loudspeaker. 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. Prolonged excess volume
will lead to hearing loss.
WARNING
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.
