- The symbol numbers shown on the P.C. Board list can be matched with the Composite Views of components of the Schematic Diagram or Service Manual.
- The indications of Resistors and Capacitors in the photos of P.C. Board are being eliminated.
- The shape of the parts and parts name, etc. can be confirmed by comparing them with the parts shown on the Electrical Parts Table of P.C. Board.
- Both the kind of part and installation position can be determined by the Parts Number. To determine where a parts number is listed, utilize Parts Index at end of Parts List. It is necessary first of all to find the Parts Number. This can be accomplished by using the Reference Number listed at right of parts number in the Parts Index, (meaning of ref. no. outlined in Item 3 above).
- Utilize separate "Price List for Parts" to determine unit price. The most simple method of finding parts Price is to utilize the reference number.
CAUTION:
- When placing an order for parts, be sure to list the parts no. model no., and description. There are instances in which if any of this information is omitted, parts cannot be shipped or the wrong parts will be delivered.
- Please be careful not to make a mistake in the parts no. If the parts no. is in error, a part different from the one ordered may be delivered.
