NOTE FOR SCHEMATIC DIAGRAMS

PD-F1005, PD-F905

3. SCHEMATIC AND PCB DIAGRAMS

(Type 4A)

1. When ordering service parts, be sure to refer to

"PARTS

LIST of EXPLODED

VIEWS"

or "PCB

PARTS

LIST".

. Since these are basic circuits, some

parts of them or the

values of some components may be changed for improve

ment.

. RESISTORS:

Unit: k:kQ, 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% un-

lass otherwise noted.

. CAPACITORS:

Unit: p:pF or uF unless otherwise noted.

Ratings: capacitor (uF)/voltage(V) unless othrewise noted.

Rated voltage: 50V except for electrolytic capacitors.

. COILS:

Unit: m:mH or pH unless otherwise noted.

. VOLTAGE AND CURRENT:

ore V:

DC voltage (V) in PLAY mode unless otherwise noted.

<3 mA or © mA:

DC current in PLAY mode unless otherwise noted.

Value in(

) is DC current in STOP mode.

. OTHERS:

*@ or@ : Adjusting point.

: Measurement point.

¢ The A mark found on some component parts indicates the im-

portance of the safety factor of the parts. Therefore, when re-

placing, be sure to use parts of identical designation.

. SCH-C] ON THE SCHEMATIC DIAGRAM:

* SCH-O indicates the drawing number of the schematic dia

gram. (SCH stands for schematic diagram.)

. SWITCHES (Underline indicates switch position):

NOTE FOR PCB DIAGRAMS

1. Part numbers in PCB diagrams match those in the schematic

diagrams.
