S1. About Indication of The Schematic Diagram

S1.1. Important Safety Notice

COMPONENTS IDENTIFIED WITH THE MARK
FOR SAFETY. WHEN REPLACING ANY OF THESE COMPONENTS USE ONLY THE SAME TYPE.
1.Although reference number of the parts is indicated on the P.C.B. drawing and/or
schematic diagrams, it is NOT mounted on the P.C.B. when it is displayed with "$" mark.
2.It is only the "Test Round" and no terminal (Pin) is available on the P.C.B.
when the TP (Test Point) indicated as "
3.The voltage being indicated on the schematic diagram is measured in
"Standard-Playback" mode when there is no specify mode is mentioned.
4.Although the voltage and waveform available on here is measured with standard frame,
it may be differ from actual measurement due to modification of circuit and so on.
5.The voltage being indicated here may be include observational-error (deviation) due to
internal-resistance and/or reactance of equipment. Therefore, handle the value
indicated on here as reference.
6.Use the parts number indicated on the Replacement Parts List .
