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.

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 and part value 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 jumper wire across a hole in P.C.B.
: Test point with 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.
