Keeping the display clean
Do not touch the display screen with bare hands. The display screen is easily soiled with hand grease.
Use a soft, dry cloth to clean the display screen surface. Do not use organic solvents.
The screen surface is sensitive to scratches or other physical damage. Avoid pushing on it strongly or rubbing it with a hard cloth or
any other scratchy material.
NOTE
The screen is made of a liquid crystal display (LCD) panel. When the system is turned on in an extremely low outside tem-
perature, the LCD takes a relatively long time to become bright. On the other hand, when the outside temperature is high,
the LCD may become darker than usual. Both conditions are normal.
Images on an LCD screen may contain some tiny black spots and/or bright spots. They reflect a characteristic normal to
the LCD and do not indicate any abnormal condition.
