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.
