Translated Description from PIKO: Replaces the radio receiver #35018.The radio receiver converts the radio data of the navigator into digital or analog signals for the digital control center (35010) or the analog speed controller (35002). Thanks to its bidirectional FM radio technology, the radio receiver works very interference-free even over longer distances (approx. 100 m). A plug-on antenna is included. By means of the enclosed bus cable, the radio receiver is connected directly to the digital command station or the analog speed controller. The receiver is splash proof. Works only with the Navigator 35037
