1. SAFETY INFORMATION
(FOR USA MODEL ONLY)
1.SAFETY PRECAUTIONS
The
following
check
should
be
performed
for
the
continued
protection
of
the
customer
and
service
technician.
LEAKAGE CURRENT CHECK
.Measure
leakage
current
to
a
known
earth
ground
(water
pipe,
conduit,
etc.)
by
connecting
a
leakage
current
tester
such
as
Simpson
Model
229-2
or
equivalent
between
the
earth
ground
and
all exposed
metal
parts
of
the
appliance
(input/output
terminals,
screwheads,
metal
overlays,
contro!
shaft,
etc.).
Plug
the
AC
line
cord
of
the
appliance
directly
into
a
120V
AC
60Hz
outlet
and
turn
the
AC
power
switch
on.
Any
Current
measured
must
not
exceed
0.5mA.
A Reading should

Test all
exposed metal

ANY
MEASUREMENTS
NOT
WITHIN

2.PRODUCT SAFETY NOTICE
Many
electrical

parts
in
the
ap
pli-
ance
have
special
safety
related
characteristics.
These
are
often
not
evident
from

inspection
no:
the
protection
afforded
by
them
necessarily
can
be
ob-
tained
by
using
replacement
components
rated
fo:
vol-
tage,
wattage,
etc.
Replacement
parts
which
have
these
special
safety
characteristics
are
identified
in
this
Service
Manual.
Electrical
components
having
such
features
are
identified
by
marking
with

Additional Laser Caution
1. Laser Interlock Mechanism
The ON/OFF (ON: fow level, OFF: high level) status of the
LPS1 (S601) and LPS2 (S602) switches for detecting the loading
state is detected by the system microprocessor, and the design
prevents laser diode oscillation when both switches LPS1 and
LPS2 are not ON (low level)(clamped state).
Thus, interlock will no longer function if switches LPS1 (S601)
and LPS2(S602) are deliberately shorted.
Also, in the test mode*, the interlock mechanism does not
operate too.
Laser diode oscillation will continue if pins 2 and 3 of CXA1471S
(1C101) are connected to ground or pin’20 is connected to high
level (ON) or the terminals of Q101 are shorted to each other
(fault condition).
CAUTION
INVISIBLE LASER
RADIATION WHEN OPEN,
AVOID EXPOSURE
TO BEAM
2. When the cover is opened with the servo mechanism block
removed to be turned over, close viewing of the objective lens
with the naked eye will cause exposure to a Class 1 or higher laser
beam.

k; kQ,M; M9, (F); £1%, (G); 2%, (K); 10%, (M); 20% tolerance.
2.CAPACITORS :
Indicated in capacity (uF)/voltage(V) unless otherwise noted p; pF. Indication
without voltage is 50V except electrolytic capacitor.
3.VOLTAGE, CURRENT :
; DC voltage (V) at play state.
mA; DC current at play state.
Value in ( ) is DC current at stop state.
4.OTHERS :
=> ; Signal route.
@ ; Adjusting point
The A\ mark found on some component parts indicates the inportance of the
safety factor of the part. Therefore, when replacing, be sure to use parts of
identical designation.
3X marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may vary due to
improvements in design.
