Operation

1. Connect the receiver to a power outlet and turn it on.

2. Put two AA alkaline batteries into the battery compartment of the microphone. Please make sure to observe proper polarity.

3. Power on the microphone(s). In case of any frequency interference, quickly press the power button on the microphone to change the frequency. There are up to 8 frequencies available. Please note that it will take a few seconds for the receiver to automatically sync with the mic whenever the mic frequency is changed.

4. When first used, the receiver and mics are not matched. The receiver and mics can be used interchangeably, but if more than 1 set of mics and receivers is being used, each set of mics must be specifically matched to the corresponding receiver. Otherwise, you cannot use more than one set in a location.

Please note: If there is no sound input to the mics for more than 5 minutes, they will automatically shut down in order to conserve battery life.

Matching the Receiver and Mics

1. Connect the receiver to a power outlet and turn it off.

2. Turn the mic off. Hold the power button until the numbers flash. Press the power button again. The icon should also begin to flash.

3. Quickly turn on the receiver (within 2 seconds). The RF A LED will light. That mic is now matched to channel A. Repeat these steps for the other microphone.

Please note: Even though the mics are matched to a specific channel, you cannot use the same frequency on both mics.

Tip: To minimize feedback avoid operating the microphones in close proximity of or in front of speakers.
