SCHEMATIC DIAGRAM AND CIRCUIT BOARD LAYOUT NOTES
1. Important safety notice
Components identified by the sign
have special charac-
teristics important for safety. When replacing any of these
components. Use only the specified parts.
2. Do not use the part number shown on this drawing for or-
dering. The correct part number is shown in the parts list,
and may be slightly different or amended since this draw-
ing was prepared.
3. Use only original replacement parts:
To maintain original function and reliability of repaired units,
use only original replacement parts which are listed with
their part numbers in the parts list section of the service
manual.
4. Parts different in shape or size may be used.
However, only interchangeable parts will be supplied as
service replacement parts.
5. Test point information
:Test point with a no test pin.
Schematic Diagram Notes
1. Indication for Zener Voltage of Zener Diodes
The Zener Voltage of Zener Diodes are indicated as such
on Schematic Diagrams.
Example:
(6.2V)......Zener Voltage
2. How to identify Connectors
Each connector is labeled with a Connector No. and Pin No.
Indicating what it is connected to, in other words, its counter
part.
Use the interconnection schematic diagram to find the
connection between associated connectors.
Example:
The connections between C.B.A.s are shown below.
MAIN C.B.A.
RELAY C.B.A.
The Number of pins of the Connector.
Connector No. on Main C.B.A.
P2
P9001
E64 (13 Pins)
Ref. No. of the connection parts such as lead cable,
flexible cable which is supplied as a replacement parts.
3. Parts enclosed in dashed lines marked “Z” are not used in
any models included in this service manual.
