8. Schematic Diagram Notes8.1. Schemtic Diagram NotesThis schematic diagram may be modified at any time with the development ofnew technology.Notes:- S201 : Volume (VOLUME +) switch.- S202 : Volume (VOLUME -) switch.- S203 : F. skip / search ( ) switch.- S204 : R. skip / search ( ) switch.- S206 : Play / stop ( ) switch.- S207 : Cover open / close det. switch.- S208 : Hold switch in “OFF” position.- Indicated voltage values are the standard values for the unit measured by theDC electronic circuit tester (high-impedance) with the chassis taken asstandard. Therefore, there may exist some errors in the voltage values,depending on the internal impedance of the DC circuit tester.No mark: MD STOP( ): MD play [1kHz, L+R, 0dB]Important safety notice:Components identified by mark have special characteristics important forsafety.Furthermore, special parts which have purpose of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. When replacingany of components, be sure to use only manufacture's specified parts shown inthe parts list.Caution!IC and LSI are sensitive to static electricity.Secondary trouble can be prevented by taking care during repair.Cover the parts boxes made of plastics with aluminum foil.Ground the soldering iron.Put a conductive mat on the work table.45
