Lectrosonics SR170AC - Manual (Page 3)

RECEIVER FRONT PANEL
MODULATION - Indicates the modulation (audio level) of the incoming signal - see transmitter manual
for proper adjustment of transmitter "MIC LEVEL" or "GAIN." The -20 lamp should flicker, or stay lit as
you speak into the microphone. The 0dB lamp is a "peak" indicator showing that the audio gain in the
transmitter is set too high. It is normal, however, to see an occasional flicker of the 0dB lamp.
POWER OFF-ON Switch - This slide switch turns the power off and on.
POWER LED - Glows when the switch is in the "ON" position and the power source is good, or when
the AC adapter is properly connected. If this LED is very dim or does not light up when the switch is
turned on, check the power source.
RF LED - Lights when the transmitter is turned on. When the carrier signal from the transmitter is too
weak to produce a clean audio signal the lamp will go out.
