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.
