HOW TO USE THIS PARTS LIST
1. This Parts List lists those parts which are considered necessary for repairs. Other common parts, such as resistors and
capacitors, are listed in the “Common List for Service Parts” from which these parts should be selected and stocked.
2. Parts not shown in the Parts List and “Common List for Service Parts” will not in principle be supplied.
3. How to read the Parts List.
ATTENTION
1. When placing an order for parts, be sure to list the Part No., Model No, and the description of each part. Otherwise, the
non-delivery of the part or the delivery of a wrong part may result.
2. Please make sure that Part No. is correct when ordering.
If not, a part different from the one you ordered may be delivered.
3. Since the parts shown in Parts List of Preliminary Service Manual may have been the subject of changes, please use this
Parts List for all future reference.
