can distort the picture or cause a malfunction. The picture may
become unclear or it may damage the LCD panel.
• Notes on cleaning

Use mild household detergent.
— Do not use solvents such as benzine, thinner, commercially
available cleaners, or antistatic spray.
• Do not use this unit in temperatures under 5° C or over 45° C.
• If your car was parked in a cold or hot place, the picture may not
be clear. The monitor is not damaged. The picture will become

Some stationary blue or red dots may appear on the screen.
