: nonflammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation and adjustment for repair.
•
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
•
Voltage value is the reference value between it and the earth, when
component RGB signal are received from didital video generator
(digital multi-meter used : 10 M ohms/V DC).
•
Unit of voltage values is V (volt).
•
No mark : Common and signal in (S2 in side).
•
( ) : Signal out (S2 out side).
•
Circled numbers are waveform reference.
•
: Signal Path.
