Important
Precautions

On Installation
Do not allow
anything
to rest
upon
or roll over the
power
cord,
and do not
place
the
display
where the
power
cord is
subject
to
damage.
Do not use this
display
near water such as near a
bathtub, washbowl,
kitchen
sink,
laundry
tub,
in
a wet
basement,
or near a
swimming pool.
Displays
are
provided
with ventilation
openings
in
the cabinet to allow the release
of heat
generated during operation.
If
these
openings
are
blocked,
built-up
heat
can cause failures which
may
result
in
a fire hazard.
Therefore,
NEVER:
Block the bottom ventilation slots
by placing
the
display
on a
bed, sofa,
rug,
etc.
Place the
display
in
a built-in enclosure unless
proper
ventilation is
provided.
Cover the
openings
with cloth or other material.
Place the
display
near or over a radiator or heat source.
Do not rub or strike the Active Matrix LCD with
anything
hard as this
may
scratch,
mar,
or
damage
the Active Matrix LCD
permanently.
Do not
press
the LCD screen with
your finger
for a
long
time as this
may
cause
some
afterimages.
Some dot defects
may appear
as
Red,
Green or Blue
spots
on the screen.
However,
this
will
have no
impact
or effect on the
display performance.
If
possible,
use the recommended resolution to obtain the best
image quality
for
your
LCD
display.
If
used under
any
mode
except
the recommended
resolution,
some scaled or
processed images may appear
on the screen.
However,
this is
characteristic of the fixed-resolution LCD
panel.
On
Cleaning
Unplug
the
display
before
cleaning
the face of the
display
screen.
Use a
slightly damp
(not wet)
cloth. Do not use an aerosol
directly
on the
display
screen because
over-spraying may
cause electrical shock.
On
Repacking
Do not throw
away
the carton and
packing
materials.
They
make an ideal
container
in
which to
transport
the unit. When
shipping
the unit to another
location,
repack
it
in
its
original
material.
On
Disposal
The fluorescent
lamp
used
in
this
product
contains a small amount of
mercury.
Do not
dispose
of this
product
