Mechanism deck and main board and panel board has been changed.
Changed schematic diagram, printed wiring board, exploded views and electrical parts list are published in this SUPPLEMENT-3.
About the interchangeability of former and new parts
The mechanism deck of a new type and the boards of a new type should synchronize.
Therefore, it is not compatible in the mechanism deck and main board and panel board of former and new.
Please use parts of a new type referring to “NEW TYPE IDENTIFICATION” for the set of a new type.

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
 : LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40
°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350
°C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
NEW TYPE  IDENTIFICATION
Please see the part code of the main board or the part code of the mechanism deck and distinguish former type or new type of the set.
