Do not cover the infrared emitter area of the wireless transmitter or the surface of the infrared
sensor.

Since the unit uses infrared reflectance. Do not expose receiver to the black ceiling or wall
because it may reduce the signal reception.

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.
