Many electrical and mechanical parts in the appli-
ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob-
tained by using replacement components rated for vol-
tage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components having such features are
identified by marking with a A on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
dose
not
have
the
same
safety
characteristics
as
the
PIONEER
recommended
replacement
one,
shown
in
the
parts
list
in
this
Service
Manual,
may
create
shock,
fire, or other hazards.

3. SCHEMATIC AND PCB CONNECTION DIAGRAMS
NOTE FOR SCHEMATIC DIAGRAMS
(Type 1A)
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 parte of them or the
values of some components may be changed for improve-
ment.
3. RESISTORS:
Unit: &:kQ, M:MQ, or 2 unless otherwise noted.
Rated power. 1/4W, 1/6W, 1/8W, 1/10W unless otherwise noted.
Tolerance:(F): = 1%, (G): = 2%, (IK): = 10%, (M): + 20% or +5%
unless otherwise noted.
4. CAPACITORS:
Unit : p:pF or ;:F unless otherwise noted.
Ratings : capacitor (1: F) / voltage (V) unless otherwise noted.
Rated voltage : 50V except for electrolytic capacttors.
5. COILS:
Unit : m:mH or 4H unless otherwise noted.
6. VOLTAGE AND CURRENT:
(¥V) : Signal voltage at rated output.
T_jor «Vv
DC voltage (V) at no input signal unless otherwise noted.
Value in( ) is OC voltage at rated power.
mA or «+-mA:
OC current at no Input signal unless otherwise noted.
7. OTHERS:
e2or@ _— : Adjusting point.
e@ << : Measurement point.
@The A mark tound 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.
