Touchscreen
Maintaining the performance of the touchscreen
When the touchscreen becomes dirty, wipe it with an approved soft cloth
The touchscreen is specially treated to prevent dirt from adhering to the surface, so dirt can be removed easily using a dry
cloth (use only the approved soft cloth). If the dirt does not come off easily, breathe on the surface and try again.
Do not apply water or solvents to the soft cloth.
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 fingerprint, 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.
• While wiping the LCD display, the computer must be turned off.
Clean the touchscreen while the computer is powered off
Cleaning the screen while the power is on may cause the computer to malfunction. Also, dirt on the touchscreen is easier
to see when the computer is powered off, and so is easier to clean.
Wash the soft cloth when it becomes dirty
When the soft cloth becomes dirty, wash it with mild detergent. Do not use bleach or fabric conditioner (softener), or try to
sterilize the cloth by boiling.
If the soft cloth is dirty, it may be ineffective in cleaning the touchscreen, and in fact may cause dirt to adhere to the touch-
screen.
