PURPOSE:To provide an infrared remote control transmission equipment which is easily positioned in such place that it is stably operated against the degradation of the transmitter/receiver function. CONSTITUTION:An infrared attenuation material 20 formed into a film is set in front of a light emitting diode 6 which is the infrared light emitting part of an infrared remotely controlled transmission equipment 19. Consequently, the operation of a receiver is confirmed with the transmitting capability degraded when the remote control installation position is determined at the time of construction, thereby easily finding the position allowing a margin for transmitting capability. |
