Suggestions About Cleaning the LCD Surface
To improve the outdoor visibility of the display, a low reflection coating has been added. In order to avoid scratches and
peeling of this coating, an approved soft cloth has been included to wipe the LCD surface of the computer. Before using the
computer, be sure to read the instructions provided below.
• Be sure to wipe the LCD display to remove fingerprints, etc., with the soft cloth.
• Do not wipe areas other than the LCD display with the soft cloth.
<How to use the soft cloth>
Use the soft cloth when it is dry. Do not apply water or solvents to the soft cloth.
First, lightly wipe foreign particles and dust adhering to the LCD display on one side of the soft
cloth. Do not use force, since the LCD surface may be damaged with the foreign particles or dust.
Next, wipe off fingerprints, etc., with the other side of the soft cloth. After wiping off foreign particles
and dust, wash the soft cloth (refer to the following) to remove the foreign particles and dust from
the soft cloth.
When the soft cloth becomes dirty, wash it with neutral detergent. Do not use bleach or a fabric
conditioner (softener), or carry out sterilization by boiling.
If the LCD gets wet, wipe the surface lightly with the soft cloth.
We recommend wiping the LCD display before using the computer.
