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.
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.
3.The voltage being indicated on the schematic diagram is measured in
"Standard-Playback" mode when there is no specify mode is mentioned.
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 " " mark.
