This signal is connected
to the FEP schematic diagram.
Circuit name being connected.
6.Use the parts number indicated on the Replacement Parts List .
7.Indication on Schematic diagrams:
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.
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.
FOR SAFETY. WHEN REPLACING ANY OF THESE COMPONENTS USE ONLY THE SAME TYPE.
COMPONENTS IDENTIFIED WITH THE MARK
