8.Verify reception. With the transmitter and receiver on and matching Group and Channel, the main receiver display should be indicating a RF signal on the bar graph. Speak into the microphone and the Audio Meter bar graph should indicate audio signal presence. If the level meters do not show reception, make sure the channels are matching and refer to the trouble shooting section.

9.Adjustment of the transmitter audio gain - If necessary The transmitter audio gain is factory set at the middle of the range, which should be suitable for most applications. For loud or soft speakers/singers, a gain adjustment may be necessary. Have the speaker or singer use the micro- phone in a normal performance level voice. The Audio Meter in the main receiver display screen should show peaks around the -3dB level. If the meter peaks all the way to the right or well below the -3dB level, adjust the trans- mitter audio gain.

To adjust the transmitter gain, gently insert the provided screwdriver (or other 3/32 - 2.5 mm screwdriver) into the adjustment hole opposite the display screen. Turn lightly until the screwdriver tip goes into the adjustment level control. Gently turn counterclockwise until the control stops (the microphone output is at minimum but not off). Slowly turn the gain control up (clockwise) while speak- ing/singing into the microphone and the audio meter shows peaks around -3 dB.

NOTE: Operating with the transmitter audio gain set as high as possible (without distortion or peaks all the way to the right end of the meter) will result in the best perfor- mance and highest signal to noise ratio.

10.Test Performance. Go back to Section 3. Receiver Setup and Operation - Step 9 to complete system set up and test.
