MAINTENANCE

To prevent damage to the exterior
• Do not apply pesticides, benzine, thinner or other volatile substances to the unit.
The cabinet surface primarily consists of plastic materials.
• Do not wipe with benzine, thinner or similar substances because this will results in
discoloration or removal of the paint.
• When a cloth with a cleansing chemical is used, follow the caution points.
– Do not leave the unit in contact with rubber or vinyl products for long periods of time.
– Do not use cleansers which have polishing granules because this could damage the
surface of the unit.
Clean off dirt by wiping lightly with a soft cloth
When the unit is very dirty, wipe with a well-wrung cloth dipped in a kitchen cleanser (neutral)
thinned by water and then go over the same surface with a dry cloth.
(Since there is the possibility of water drops getting inside of the unit, do not directly apply
cleanser to the surface.)
Caution:
If water drops or similar wet substances get inside of the monitor via the liquid crystal panel surface,
it may cause a malfunction.
