Cleaning and Maintenance

Section

Cleaning

Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked)

with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the

screen surface to avoid scratching it with accumulated grit.

Do not use paper products as they may scratch the surface. To minimize the risk of abrasion,

allow the screen to stand dry.

Special care should be taken when cleaning a touch screen or polycarbonate shield that is

installed over the screen. Abrasive and certain chemical cleaners can easily damage the

surface.

Never use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a touch

screen.

Replacing a Line Cord

To avoid shock and fire hazards, the monitor’s power cord should be replaced if the insulation

becomes broken or if it develops a loose internal connection.

Other Maintenance

Qualified service personnel should perform all maintenance, except for the power cord

replacement described above.

Note: The solvent (a 50/50 mixture isopropyl alcohol and water) should be applied only to the

cloth, and not directly on the monitor screen.
