1. SAFETY INFORMATION
This service manual is Intended for qualified service technicians; It Is not meant for the casual
do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
trained to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may void
the warranty. If you are not qualified to perform the repair of this product properly and safely, you should
not risk trying to do so and refer the repair to a qualified service technician.
WARNING
Lead in solder used In this product Is listed by the California Health and Welfare agency as a known reproductive toxicant which
may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with
the solder. Also, when soldering do not inhale any smoke or fumes produced .

Additional Laser Caution ----- - -.
1. Laser Interlock Mechanism
The position of the switch (S902) for detecting loading
completion is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch ($902) is not in CLMP terminal side (when the
mechanism is not clamped and CLMP signal is high level).
Thus, the interlock will no longer function if the switch
(S902) is deliberately set to CLMP terminal side. (if CLMP
signal is low leve l) .
In the test mode * the interlock mechanism will not
function.
Laser diode oscillation will continue, if pin 4 of TA2066F
(IC204) on the MOTHER board assy are connected to
GND, or pin 19 is connected to high level (ON), or else the
t er minals of 0206 are shorted to each other ( fault
condition ).
2. When the cover is opened, close viewing of the Objective
lens with the naked eye will cause exposure to a Class 1
laserbeam.

2. PACKING, EXPLODED VIEWS AND PARTS LIST
NOTES:
•Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
• The .&, markfound on some componentparts indicates the importance of the safetyfactor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
•Parts marked by "@ " are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
•Parts list without notice are commonfor DR- UA/24X-2, DR- UA124X-3 and DR- UA/24X-5.
