3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try
breathing on the surface to create a light condensate and wipe it again.
If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent to a cloth
and then wipe the panel’s surface. Do not apply cleanser directly to the panel. Also, never
scratch the surface.
4. If water or other liquid is left on the panel’s surface for a long period, it can change the
screen’s tint or stain it. Be sure to quickly wipe off any liquid.
