When the microphone is turn on, the green power indicator light should be illuminated.
If the battery is low, this indicator light will turn to red.
*Do not block emitter diodes with hand.
*Bring the microphone close to one of the infrared sensors and make sure the infrared
sensor picks up the microphone signal. (Do this while making sure that the other
infrared sensor cannot receive the signals.)
If the sensor does not receive the microphone's signal, or if the sensitivity is poor, check
the cable connection.
