Gently wipe the screen film and unit with a water dampened cloth that has been thoroughly wrung.

(If you accidentally write on the screen with an oil-based marker, wipe with a small amount of ethyl alcohol.)
2. Do not use thinner, benzine or cleaners containing abrasives or surfactants, as this may result in discoloration or
difficulty of erasing.
3. Do not wipe the screen film with a dry cloth as this may generate a static charge.
