Hi Mike, Reply to Question #1: Radiated emission tests have been performed with three orthogonal axes and attached please find supplementary test data (file name: F930077-JowTon Supplement Data) Reply to Question #2: We have revised FCC ID Lable. EUT doesn't have any receiver function and we removed FCC DoC Logo from the Multi-Player. We added the FCC DoC Logo on the label of desktop docketing because the desktop docketing is as pc peripheral's peripheral. (file name: JowTon-ST28_QPRST28_Label Format) Reply to Question #3: Our engineer's reply "We have revified the maker cann't mark on 26 dB of carries frequency position, but the report mark position indicated the frequency and exact the same 26 dB down of carries frequecny (unit : 5dB). Reply to Question #4: There aren't PCB antenna on the PCB Board and that desktop docketing does not have any transmitting / receiving functions. Desktop docketing has neither PCB antenna nor transmitting / receiving function. (Attached plesase find schematic for your reference) Please kindly process this applciation as quickly as possible.
