  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 "    " mark.
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 .
COMPONENTS IDENTIFIED WITH THE MARK       HAVE THE SPECIAL CHARACTERISTICS
FOR SAFETY. WHEN REPLACING ANY OF THESE COMPONENTS USE ONLY THE SAME TYPE.
7.Indication on Schematic diagrams:
OFTR
FEP
Circuit name being connected.
Name of Signal
This signal is connected
to the FEP schematic diagram.
S1. About Indication of The Schematic Diagram
S1.1. Important Safety Notice

S2. Voltage Chart
S2.1. Main P.C.B.
Note) Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance) with the chassis taken as standard. 
          Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester.
