Cleaning and maintenance
First, remove the mains plug from the mains socket.
The front panel surface has been specially treated.
Wipe the surface of the front panel gently using only
a cleaning cloth or a soft, lint-free cloth.
•
If the surface is particularly dirty, wipe with a soft,
lint-free cloth which has been soaked in pure water or
water in which neutral detergent has been diluted 100
times, and then wipe it evenly with a dry cloth of the
same type until the surface is dry.
Wipe off dirt on the IR transmission part with soft
cloth.
•
Wipe off dirt on the IR
transmission part with soft
cloth once a day.
If malfunction is due to dirt
on the IR transmission part,
simply wiping it off lightly can
recover the performance.
IR transmission
part
If dirt is sticky, wipe it off with cloth wrung out of
neutral detergent diluted with water and then wipe the
part with dry cloth.
•
If the substance such as the material of the supplied
pen is stuck on the glass surface, wipe it with a wet
cloth.
Note that if a deep scratch is caused by using objects
other than the supplied pen, it may not be wiped off.
•
Do not scratch or hit the surface of the front panel
with fingernails or other hard objects, otherwise the
surface may become damaged. Furthermore, avoid
contact with volatile substances such as insect
sprays, solvents and thinner, otherwise the quality of
the surface may be adversely affected.
If the cabinet becomes dirty, wipe it with a soft, dry
cloth.
•
If the cabinet is particularly dirty, soak the cloth in
water to which a small amount of neutral detergent
has been added and then wring the cloth dry. Use this
cloth to wipe the cabinet, and then wipe it dry with a
dry cloth.
•
Do not allow any detergent to come into direct contact
with the surface of the Display. If water droplets get
inside the unit, operating problems may result.
•
Avoid contact with volatile substances such as insect
sprays, solvents and thinner, otherwise the quality of
the cabinet surface may be adversely affected or the
coating may peel off. Furthermore, do not leave it for
long periods in contact with articles made from rubber
or PVC.
Usage of a chemical cloth
•
Do not use a chemical cloth for the panel surface.
•
Follow the instructions for the chemical cloth to use it
for the cabinet.
Touch panel
Carefully observe the following instructions as the
display has an optical touch panel.
Do not expose the display to direct sunlight or
strong light source during use.
•
Otherwise malfunction may occur since the optical
touch panel of the display uses infrared rays.
Always use a finger or the supplied pen to operate
the touch panel. Do not use a hard or sharp tip such
as nail, ball-point pen, and pencil.
When using any other infrared device, keep a
distance to prevent erroneous operation.
When installing multiple units
When installing multiple units side by side,
infrared rays of each unit may penetrate into the
IR transmission parts of the adjacent displays,
resulting in malfunction of touch panels.
Install the units in such a way that the displays are
not affected mutually.
Disposal
When disposing the product, ask your local
authority or dealer about the correct methods of
disposal.
