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.
