Thank you for purchasing our infrared wireless microphone system. Please be sure to read the
user's manual thoroughly and keep it for future reference.

Cautions

 Do not cover the infrared emitter area of the wireless transmitter or the surface of the infrared

sensor.

 Do not use the transmitter too close to speakers to prevent feedback.
 Do not replace the battery when power is on.
 Do not install near heat source or in a place subject to direct sunlight, excessive dust,

mechanical vibration or shock.

 Do not use two transmitters on one channel at same time because it will cause abnormal

operation.
