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.
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.
5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object,
which could cause breakage or cracks.
