Power Switch: Turns receiver power on/off. Power ON Indicator: This red light glows when the receiver is plugged into an electrical outlet and switched on. It indicates that the receiver is on. 3. Diversity Signal Indicators: The green light of diversity A/B glows when RF (radio frequency) signals are received from the transmitter. When A light is glowing, the channel A is being used, when B light is glowing the channel B is being used. 4. Audio level Indicator: Audio level indicator of receiver glows according to the volume of the transmitter when talking or singing into the microphone. 5. Volume control: Rotate this Knob to increase or decrease the volume of the receiver output. 6. Model Number of the receiver. 7. Antenna 8. Balanced Output XLR Male Socket: For obtaining balanced audio output through a 3-pin female XLR plug 9. Unbalanced Output JACK Socket: For obtaining unbalanced audio output of high or low levels, than a ¼'' phono jack 10. DC Input Socket: For connecting the DC Plug of a 12V adaptor.

USAGE TIPS -
Make sure you can always see the receiver antenna from the transmitter position. Keep the distance from transmitter to receiver as short as possible Avoid placing the receiver antennas near metal surfaces and obstruction. Perform a walk through before performance or presentation. If dead spots are found, adjust location of receiver. If dead spots remain mark spots and avoid.

Basic Troubleshooting. Issue
Solution
Receiver Indicator not lighting.
Make sure AC adapter is securely plugged into electrical outlet and into POWER connector on rear panel of receiver. Make sure AC electrical outlet works and is supplying proper voltage.
Audio light glows but no Sound.
Please check gain levels. Please check cable connections.
Distortion or unwanted noise bursts
Remove nearby sources of RF interference (CD players, computers, cell phones, digital effects, in-ear monitor systems, etc.) Reduce transmitter gain. Replace transmitter battery. If using multiple systems, change the channel of one of the active systems. Avoid using two systems with the same frequency at the same place; please separate them at least by 200 meters.
