OPERATING INSTRUCTIONS

1. Turn on the receiver using the Receiver Power Button. The LED display will show the channel and frequency of the receiver.
2. Turn the microphone volume knobs all the way down, and then press the Microphone Power Buttons to turn on each microphone. (2 x AA batteries each are required to turn on the microphones.) The LED displays will show the channel, RF and AF levels, battery status, and transmission range of each microphone.
3. To adjust the frequency, use the Frequency Adjustment Button. To access this button, unscrew the microphone base/battery cover by twisting the lower half of the handle counterclockwise until it is completely removed. Press the button marked “HI La” to change the channel/frequency. The receiver will automatically match the frequency of the transmitter. Screw the piece back on after you have selected the channel. Channels are selectable between 1 and 50.
   Microphone A and Microphone B will not interfere with each other, but if you are using multiple sets of microphones simultaneously, you should set all the microphones to different frequencies.
4. To turn off either the microphone or the receiver, press the corresponding Power Button for 2 to 3 seconds.
5. Pairing Method Turn on the receiver and turn off the mic first. Make sure both mic and receiver are within 20″ distance. Hold down the channel-adjust button of the mic first, and then press the power button of the mic. When the screen shows “ “, release both buttons and wait for seconds. If “ ” disappears, it means pairing is successful.

Note: When working with 2 sets or more simultaneously, please make sure mics are set with different channels.
