Insert the antenna into the receiver, then push and screw it all the way to the right. Make it 45 or 90 degrees from the receiver.
Connect the receiver to an AC outlet (120V/220V 50Hz). Press the power button to turn on the receiver. And you will see the display is on.
Install two 1.5V AA alkaline batteries for each mic correctly. Hold the ON/OFF button down to turn on the mic.
The RF indicators on the receiver will be on, and the frequency on the mics should be the same as the one on the receiver when the mics pair with the receiver. If not, please reset the unit manually.
Turn the volume of the powered speaker (not included) to zero. Connect one end of the audio cable to the MIX OUT on the receiver, and the other end to the MIC input jack on your powered speaker.
Adjust the mic volume with the knobs on the receiver and on the powered speaker accordingly.
