USING GUIDE INSTRUCTION

OPERATION

• Put the receiver near the audio adjustor, connect with power and the signal protected cord with A.OUT, B.OUT or MIX.OUT. And then connect with the amplifier or the microphone of the audio adjustor (MIC IN). Draw out two antennas completely. Put on the power switch, The power indicator shines. This receiver is being standing by. (Don't put the receiver in a corner in order to work in a good condition)
