speaker volume. Turn the trimmer clockwise to increase volume or counter-
clockwise to decrease volume.
You may adjust microphone sensitivity using the Microphone Sensitivity jumper
and trimmer located to the right of the speaker. For high microphone sensitivity,
place the jumper over the bottom two pins in the “H” position. For low microphone
sensitivity, place the jumper over the top two pins in the “L” position. You may also

Sensitivity trimmer. Turn the trimmer clockwise to increase sensitivity or counter-
clockwise to decrease sensitivity.
