How to use this service manual
• The "Common parts" which Marantz Japan, Inc. has established are eliminated from this
service manual.
• These "Common parts" are applied to all models in the service manuals arranged and
issued
by
MJI.
• To indicate clearly the common parts in the schematic diagram, a line is drawn above or
under the Ref. Desig. No. of applicable parts.
• "Common parts" can be supplied from the Marantz service center as ever.
In case of ordering, please establish the parts number of 10 figures following the procedure
mentioned in this service manual "How to establish the parts number for common parts".
(NOTE)
When you order parts to the Marantz parts center, please take notice of the following points.
1) Please correctly write the parts number of 10 figures following the rule.
2) Since ordering parts by the Ref. Desig. No. or ratings indicated in the schematic
diagram
does not satisfy the above conditions, the Marantz parts supply system does not work
properly.
As this case is apt to cause a trouble, please pay attention to it.
