8 SCHEMATIC DIAGRAM
8.1. SCHEMATIC DIAGRAM & CIRCUIT BOARD LAYOUT NOTE
1. Important safety notice
Components identified by the sign
have special characteristics 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 ordering. The correct part number is shown in the parts list, and may
be slightly different or amended since this drawing 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.
