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
a
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 A on
the
schematics
and
the
parts
list
in
this
Service
Manual.
The
use
of
a
substitute
replacement
component
which
does
not
have
the
same
safety
characteristics
as
the HITACHI
recommended
replacement
one, shown
in the
parts
list
in
this
Service
Manual,
may create
shock,
fire,
or
other
hazards,
Product
safety
is
continuously
under
review
and
new
instructions
are
issued
from
time
to
time.
For
the
latest
information,
always
consult
the
current
HITACHI
Service
Manual.
A
subscription
to,
or
additional
copies
for,
HITACHI
Service
Manual
may
be
obtained
at
a
nominal
charge
from
HITACHI
SALES
CORPORATION.
CAUTION (CRT EVF)
Be
careful
of
the
section
painted
in
white
on
the
electronic
viewfinder
circuit
board
as
it
generates
a
high
voltage.
CAUTION (COLOR LCD
LCD
display;
the
liquid
crystal
display
(LCD)
panel
is
mode
by
highly
precise
technology.
More
than
99.99%
of
its
picture
elements
(pixels)
are
effective,
but
some
(less
than
0.01%)
may
appear
as
colored
bright
dots.
This
mode
not
indicate
a
fault
as
the
LCD
panel
stretches
the
limits
of
current
technology.
X-RAY RADIATION
The
primary
source
of
X-ray
radiation
in
this
viewfinder
is
the
picture
tube.
The
tube
used
in
this
viewfinder
is
specially
constructed
to
limit
X-ray
radiation
emission.
For
continued
X-ray
radiation
protection,
the
replacement
tube
must
be
same
type
as
the
original,
Hitachi
approved
one.

1.8.6 Spot Noise Adjustment Procedure
Before Starting Adjustment
1. The spot noise is identified as the fine white noise
that appears when the lens cap is attached after the
power is turn on.
2. Perform this adjustment only for products with
which spot noise occurs. (However, there is no
problem even if products free from spot noise are
adjusted.)
3. After replacing the CCD image sensor or SPC
circuit board (EEPROM), check whether or not spot
noise occurs and then proceed with adjustment.
(1) Start the MAP.
