Table of Contents

• Resistor:

To differentiate the units of resistors, such symbol as K and

M are used: the symbol K means 1000 ohm and the symbol

M means 1000 kohm and the resistor without any symbol is

ohm-type resistor. Besides, the one with "Fusible" is a fuse

type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this

symbol P means pico-farad and the unit of the capacitor

without such a symbol is microfarad. As to electrolytic

capacitor, the expression "capacitance/withstand voltage"

is used.

(CH), (TH), (RH), (UJ): Temperature compensation

(ML): Mylar type

(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this

model are subject to change for improvement without prior

notice.

• The indicated voltage in each section is the one measured

by Digital Multimeter between such a section and the chas-

sis with no signal given.
