Maintenance

• To clean the cabinet or surface of the liquid crystal panel, gently wipe with a soft, dry cloth.
If the surfaces are extremely dirty, use a soft cloth dipped in a weak detergent solution and then wrung-out to clean the surfaces, then
use a dry cloth to finish. Water or similar substances getting inside the monitor can cause a malfunction.
• Never use alcohol, thinner or benzene to clean this unit.
Doing so would cause the surface of the monitor to become discolored, and cause paint to peel.
• Do not spray cleansers directly onto the monitor.
Water or similar substances getting inside the monitor can cause a malfunction.
