Remote control device

Remote control device

Reading time: 3 minute Receiving signals of approximately 38 kHz, the mount may not be sensitive to some types of remote controls that transmit on other frequencies (115kHz, in the case of remote controls for satellite receivers). The tested assembly received signals from various TV remote controls, CD player and even from TV-Tuner remote controls.
