PARTS LIST R O M HOW TO USE THIS PARTS LIST 1. This parts list is compiled by various individual blocks based on assembly process. 2. When ordering parts, please describe parts number, serial number, and model number in detail. 3. How to read list. The reference number corresponds with illustration or photo number of that particular parts list. This number corresponds with the Figure Number. This number corresponds with the individual parts index number in that figure. A small x indicates the inability to show that particular part in the Photo or Illustration. Schematic Diagram Number of individual manufactured part. (not required for parts order) Quantity of particular part required. 12-115x Ref.

Board list can be matched with the Composite Views of components of the Schematic Diagram or Service Manual. 5. The indications of Resistors and Capacitors in the photos of P.C. Board are being eliminated. 6. 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. 7. 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). 8. 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: 1. 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. 2. Please be careful not to make a mistake in the parts no. If the parts no. is in error, a part dif- ferent from the one ordered may be delivered. R O M 1.
