Parts List
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 .
7.Indication on Schematic diagrams:
OFTR
FEP
Circuit name being connected.
Name of Signal
This signal is connected
to the EFP schematic diagram
COMPONENTS IDENTIFIED WITH THE MARK HAVE THE SPECIAL CHARACTERISTICS FOR SAFETY.
