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 no test pin.
Schematic Diagram Notes
1. Indication for Zener Voltage of Zener Diodes
The Zener Voltages 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 (its counter part).
Use the interconnection schematic diagram to find the
connection between associated connectors.
Example:
The connections between two P.C.B.s are shown
below.
