for
an
extended
period
of
time,
unplug
it

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

another
location,
repack
it
in
its
original
