Water or mist residue found inside the panel surface.
If the display is brought directly from a cold place to a warm place, or the display is warm and
the temperature drops suddenly (by air-conditioning, for example), condensation may occur
on the inner side of the display surface or the protection plate. This is a natural phenomenon,
which does not affect the operation, yet it may cause damage to the unit.
Try to keep the display in a condensation-free area or power it off and wait until the
condensation disappears. Or perform the defogging function as stated in
Defogging on page
35 .
