Caution When Using the Display
• Do not bring your hands, face or objects close to the ventilation holes of the display. The
top of the display is usually very hot due to the high temperature of exhaust air being
released through the ventilation holes. Burns or personal injuries may occur if any body
parts are brought too close. Placing any object near the top of the display could also
result in heat related damage to the object as well as the display itself.
• Be sure to disconnect all cables before moving the display. Moving the display with its
cables attached may damage the cables and thus cause fire or electric shock.
• Disconnect the power plug from the wall outlet as a safety precaution before carrying
out any type of cleaning or maintenance procedure.
Front Panel Cleaning Instructions
• The front of the display has been specially treated. Wipe the surface gently using only a
cleaning cloth or a soft, lint-free cloth.
• If the surface becomes dirty, soak a soft, lint-free cloth in a mild detergent solution. Wring
the cloth to remove excess liquid. Wipe the surface of the display to remove dirt. Then
use a dry cloth of the same type to dry.
• Do not scratch or hit the surface of the panel with fingers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners.
Cabinet Cleaning Instructions
• If the cabinet becomes dirty, wipe the cabinet with a soft, dry cloth.
• If the cabinet is extremely dirty, soak a lint-free cloth in a mild detergent solution. Wring
the cloth to remove as much moisture as possible. Wipe the cabinet. Use another dry
cloth to wipe over until the surface is dry.
• Do not allow any water or detergent to come into contact with the surface of the
display. If water or moisture gets inside the unit, operating problems, electrical and shock
hazards may result.
• Do not scratch or hit the cabinet with fingers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners on the cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any extended
periods of time.
