employs
laser.
Therefore,
be
sure
to
follow
carefully
the
instructions
below
when
servicing.
Warning
When
servicing,
do
not
approach
the

eye
too
closely.
In
case
it
is
necessary
to
confirm laser
beam
emission.
Be
sure
to
observe
from
a distance of
more
than
30
em
from
the
surface of
the
objective
lens
on
the
optical
pick-up
block.
£ Cautio"' Invisible laser
radiation
when
open
and
interlocks
defeated
avoid exposure
to
beam
Caution
Use
of controls or adjustments or performance of procedures other
than
those specified
herein
may
result
in
hazardous
radiation
exposure.
This

SAFETY PRECAUTIONS
Notice:
Comply
with
all
cautions
and
safety
related
notes
located
on
or inside
the
cabinet
and
on
the
chassis.
I.
When
replacing a chassis
in
the
console,
all
the
protective devices
must
be
put
back
in
place,
such
as
barriers, non-metallic
knobs,
adjustment
and
compartment covers/shields, isolation resistors/capacitors,
etc.
'
When
service
is
required, observe
the
original lead-dress. Extra precautions
should
be
taken
to
assure correct
lead
dress
in
the
high
voltage circuit.
3.
Always
use
the
manufacturer's replacement components. Especially critical components
as
indicated
on
the
circuit diagram
should
not
be
replaced
by
other manufacturer's. Furthermore, where a short-circuit
has
occurred, replace those components
that
indicate evidence of overheating.
PRODUCT SAFETY NOTICE
Many
electrical
and
mechanical
parts
have
special safety-related characteristics. These are
often
not
evident
from
visual
inspection
nor
can
the
protection afforded
by
them
necessarily
be
obtained
by
using
replacement components
rated
for higher
voltage, 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
a it,
in
the
parts
list
in
this Service
Manual.
The
use
of a substitute replacement component
which
does
not
have
the
same safety characteristics
as
the
SEGA
recommended
replacement
one,
shown
in
the
parts list
in
this
Se[Vice
Manual,
may
create shock,
fire,
or other hazards. Product Safety
is
continuously under
review
and
new
instructions
are
issued
from
time
to
time.
