Infrared Detector

Infrared detector for 5-line infra-red emitter: After power is connected to the infra-red emitter, if the green light of the emitter and the red light of the receiver are both lighted, it means that the emitter and the receiver are not on the same level and not in the same straight line. Then, the position of either the emitter or the receiver needs to be adjusted to ensure that they are at the same level and in a straight line. With proper leveling and lining, the red light of the receiver will be out. When this is so, the remoter will function properly. Packing: Carton
