cause malfunction.
To avoid this problem a gap of 0.5mm or more should
be left between the display bezel edges at installation.
Do not take hold of the display in such a way that
your fingers or hands put pressure on the liquid
crystal panel.
•
Do not put force on the liquid crystal panel, or press
or push it, or allow it to make contact with a hard or
sharp object. Applying force to the liquid crystal panel
can distort the screen, make it uneven, and cause
malfunction .
Changes of temperature or humidity may cause the
brightness of the display to be uneven. This is not a
malfunction.
•
The unevenness will disappear after the display has
been running for some time. If the problem persists,
consult the distributor.
Red, blue or green dots on the screen are a liquid
crystal panel-specific phenomenon. This is not a
malfunction.
•
Although the liquid crystal display is manufactured
with high-precision technology, always-lighting dots or
non-lighting dots may appear on the screen. This is
not a malfunction.

Notes on Using Wired LAN
Take the necessary antistatic measures before
setting up the Display in a location prone to
electrostatic interference.
•
If the Display is used in a place where electrostatic
discharge is frequent, such as in a carpeted venue,
disconnection of a wired LAN can become a nuisance.
In such a case, remove the source of the problem,
relocate the LAN cable, and install an anti-static mat.
•
In rare cases, a LAN connection can be disabled by
static electricity or noise. Turning the power to the
Display and all the connected devices, off and on again,
will most times restore the LAN connection.
The Display may not work properly in the presence of
strong radio waves from a broadcast station or even
a radio.
•
If there should be a facility or equipment, which
outputs strong radio waves near the installation, move
the Display to a place far enough away to avoid the
problem. Or the LAN cable can be shielded by a
wrapping of metal foil that is continuous with the LAN
terminal ground, or by being placed inside a metal
conduit which is properly grounded at both ends.
Cleaning and maintenance
The front of the liquid crystal panel has been specially
treated. Wipe the surface of the liquid crystal panel
gently using only an LCD cleaning cloth, or other soft
lint-free cloth.
•
If the surface is particularly dirty, wipe with a soft, lint-
free cloth which has been slightly damped with pure
water, or water to which one drop of a neutral detergent
has been added. After this wipe with a lint-free cloth until
the surface is dry.
•
Do not scratch the surface of the panel with a fingernail
or other hard object to remove dirt, this may damage the
surface. Furthermore, avoid spraying insect repellant
near the display and also avoid using any kind of solvent
such as thinners near the screen. These fluids can have
an adverse effect on the surface.
If the housing becomes dirty, wipe it with a soft, dry
cloth.
•
If the housing should become particularly dirty, wipe it
with a cloth slightly damped with water to which a drop
of neutral detergent has been added. Use this cloth to
wipe the cabinet and then wipe it dry with another cloth.
•
Do not allow any detergent to come into direct contact
with the surface of the Display. Make sure the cloth is
only damp. If water droplets get inside the unit, operating
problems may be the result.
•
Volatile substances such as insect sprays, solvents
and thinners, can harm not only the screen but also the
Display housing. The coating may be adversely affected
and may even peel off. Do not allow articles made of
rubber or PVC to remain in contact with the Display
housing for any length of time.
Using a chemical cloth
•
Do not use a chemical cloth on the panel surface.
•
Follow the instructions for using the chemical cloth on
the Display housing.
Disposal
When you wish to dispose of this product, ask your
