Replacing
consumables
(1)
Replacing
an
electric
lamp
(halogen
lamp)
First,
unplug
the
power
cable
from
the
outlet.
Then,
turn
the
instrument
and
remove
4
screws
on
bottom
of
upper
part
of
the
instrument
and
remove
the
upper
instrument-cover.
Refer
Fig.1.
Pull
the
halogen
lamp
upward,
and
it
will
be
easily
detached
from
the
receptacle
in
the
lamp
housing.
Insert
the
lead
of
a
new
halogen
lamp
into
the
hole
of
the
receptacle.
Refer
Figure
10.
ANCautions
(a)
Do
not
touch
the
halogen
lamp
with
bare
hands.
Otherwise,
fingerprint
will
adhere
to
the
lamp
surface
to
adversely
affect
the
projected
light
or
chart
image.
Be
sure
to
wrap
the
lamp
with
paper
or
cloth
and
then
attach
or
detach
the
lamp.
When
the
lamp
gets
dirty,
wipe
it
using
cloth
moistened
with
alcohol.
(b)
Do
not
replace
the
lamp
when
it
lights
or
immediately
after
it
goes
out,
because
the
lamp
or
the
lamp
housing
lid
is
very
hot.
See
Figure
10.
(c}
Replace
a
halogen
lamp
with
a
spare
or
the
same
kind
of
(genuine)
part.
The 12V
and
30W
halogen lamps
very
in
size,
filament
shape,
or
diameter
of
bulb
lead
depending
on
the
manufacturer.
if
an
unspecified
lamp
is
used,
it
may
not
attached
firmly
or
cannot
yield
satisfactory
illumination
level
or
color tone.
Therefore,
be
sure
to
use
a
spare
or
a
genuine
part.
(d)
Make
sure
that
the
filament
of
a
halogen
lamp
is
properly
positioned.
The
filament
improperly
positioned
may
cause
deviation
in
illumination
level
in
the
viewing
field
even
if
the
lamp
is
not
dirty.
(e)
To
adjust
the
position
of
the
filament,
turn
on
the
power
switch
to
light
the
halogen
lamp.
Place
white
paper
vertically
at
a
distance
of
50
to
80mm
from
the
projection
lens
(3)
mounted
at
the
front
side
of
the
main
unit.
Then,
two
images
of
the
filament
in
the
halogen
lamp
will
appear
in
a
vertical
row
in
the
circular
illumination
field.
Therefore,
position
the
filament
so
that
the
two
images
will
be
identical
in
size,
providing
uniform
brightness
if
any
of
the
images
is
dim,
parted
widely,
or
deviated
sideways,
brightness
will
vary
and
illumination
level
will
be
insufficient.
Adjust
the
position
if
the
filament.
Push
the
top
of
the
halogen
lamp
with
the
handle
of
a
metal
screwdriver
(set
screwdriver)
forward
and
back
ward,
or
laterally
so
that
two
filament
images
will
be
focused
uniformly.
Be
careful
not
to
bend
the
lamp,
or
it
will
be
damaged.

Note:
Ask

@in

line.
-
@When
two
lines
are
overlapped
or
seen
separately,
a
defect
in

is
identified.
In
case
of
esophoria,
the

allows
the

to

For

is
easily
fused.

it

When
