SYSTEM OPERATION
Speak into the microphone or play your instrument. If your audio system is properly set and functioning, you should hear the
sound of your voice or instrument coming through the loudspeakers. The LEDs on the receiver should also illuminate. The top
TX AUDIO LED is red and should only illuminate momentarily when you speak loudly or play your instrument loudly. Refer to
Figure 31.

Transmitter Gain Adjustment
If necessary, adjust the transmitter gain with the supplied screwdriver, as shown in Figure 32, until only the green and yellow
Audio LEDs on the receiver illuminate when you speak into the microphone or play your instrument. The red LED should only
illuminate momentarily when you speak loudly or play your instrument loudly.
