MZ-RH1
SECTION 1
SERVICING NOTES
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
OPERATION CHECK WHEN THE MAIN BOARD IS
REMOVED
In making an operation check with the MAIN board removed from
the set, short the SL463 of the MAIN board with the solder before
starting the operation check.
Note: Be sure to remove the solder used for shortcircuit after the repaire
completed.

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 viscou-s (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.
NOTES ON REPLACEMENT OF CSP (CHIP SIZE
PACKAGE) IC
Replacement of IC401, IC501, IC601 and IC701 on the MAIN board
used in this set requires a special tool.
NOTES ON REPLACEMENT OF IC801 ON THE MAIN
BOARD
IC801 on the MAIN board can not be exchanged alone. When IC801
on the MAIN board is damaged, exchange the complete MAIN
board.
NOTES ON REPLACEMENT OF IC1 AND S8 ON
THE OLED BOARD
IC1 and S8 on the OLED board can not be exchanged alone. When
IC1 and S8 on the OLED board are damaged, exchange the complete
OLED board.
