3. SCHEMATIC AND PCB CONNECTION DIAGRAMS
NOTE FOR SCHEMATIC DIAGRAM
1. When ordering service parts, be sure to refer to
"PARTS
LIST of EXPLODED
VIEWS"
or "PCB
PARTS LIST".
2. Since these are basic circuits, some parts of them or the
values of some components may be changed for improve-
ment.
3. RESISTORS:
Unit: k:kKQ2, M:MQ, or Q unless otherwise noted.
Rated power:
1/4W.
1/6W, 1/8W,
1/10W unless otherwise noted.
Tolerance:(F):
+ 1%, (G):+2%, (K):+ 10%, (M):+20% or +5%
unless otherwise noted.
4. CAPACITORS:
Unit : p:pF or u F unless otherwise noted.
Ratings : capacitor (\1 F) /voltage (V) unless otherwise noted.
Rated voltage : 50V except for electrolytic capacitors.
5. COILS:
Unit : m:mH or yH unless otherwise noted.
6, VOLTAGE AND CURRENT:
LI
or<Vv:
DC voltage (V) in PLAY mode unless otherwise noted.
mA
or <—mA:
OC current in PLAY mode unless otherwise noted.
Value in(
—) is DC current in STOP mode.
7, OTHERS:
eQor@ _ : Adjusting point.
ed
: Measurement point.
@The
A mark
found
on some
component
parts indicates
the im-
portance of the safety factor of the parts. Therefore,
when replacing,
be sure to use parts of identical designation.
8. SCH - (] ON THE SCHEMATIC DIAGRAM:
