errors in the voltage values, depending on the internal impedance ofthe DC circuit tester.No mark: MD STOP( ): MD play [1kHz, L+R, 0dB]Important safety notice:Components identified by mark have special characteristics important for safety.Furthermore, special parts which have purpose of fire-retardant (resistors), high-quality sound(capacitors), low-noise (resistors), etc. are used. When replacing any of components, be sure touse only manufacture's specified parts shown in the 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.Do not touch the legs of IC or LSI with the fingers directly.Voltage and signal line: Positive voltage line: Playback signal line: Recording signal “digital” line: Recording signal “analog” line: Mic signal line10.2.
