Microphone Operation Turn the microphone transmitter switch at the base of the microphone. The battery indicator LED will give a single quick flash; this indicates usable battery strength. In the case of a dead or low battery, the indicator will either not go on at all or will stay on continuously, indicating a battery voltage below 7V. If this occurs, replace with a fresh 9V battery. To preserve battery life, turn transmitter off when not in use. Move Audio switch at the base of the microphone to the ON position. The microphone is now ready to use. The Transmit (receive) LED indicator on the Receiver should now be lit. Receiver Volume Control Adjust Turn the Volume control on the Receiver clockwise to near full gain. Adjust volume up or down so that no audio distortion is present when amp or mixer are set at their usual levels. At full gain, the system gain is approximately 4 dB higher than a direct microphone-to-amp connection. Level Trim Adjust For optimum performance, a level trim control is provided. Adjust the microphone gain by inserting a small slot-headed screwdriver through the adjustment hole, located on the backside of the battery compartment, under the compartment cover. Set for maximum possible gain without noticeable distortion of the high level peaks. Turning Trim Control clockwise increases audio level; turning counterclockwise decreases level. 5
