Installation guide

h. Lower the volume on the microphone to an
appropriate level:
• The level of your speaking voice should be
enhanced, but not loud enough to sound
like a paging system.
• Check the LEDs on the PVS switcher. The
green Normal LED should light when you
speak, with the red Peak LED blinking
occasionally.
NOTE: The microphone audio should be
barely audible to the person speaking
into it. Have another person listen for
the audio levels and check for sound
quality.
