Avoid getting moisture inside the chassis during exterior cleaning; use
just enough moisture to dampen the cloth or swab.
Do not wash the front-panel On/Standby switch. Cover the switch while washing

alcohol solution as a cleanser and rinse with deionized or distilled water.
Do not use chemical cleaning agents; they may damage the chassis. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
The portable mainframe display is a soft plastic display and must be treated with
care during cleaning.

Improper cleaning agents or methods can damage the flat panel
display.
