operating systems: Windows 95, Windows 98, Windows 2000, Windows Me
(Millennium Edition), Windows NT, and Windows XP.

Your package includes:
• Color monitor
• DB-15 video cable

Precautions
• For best viewing conditions sit at least

COVER. The monitor contains high
voltage parts. You may suffer serious
injury if you touch these parts.
• Avoid exposing the monitor to direct
sunlight or another heat source,
including an open flame. The monitor
should be facing away from direct
sunlight to reduce glare.
• Always handle your monitor with care
when moving it.
• Place your monitor in a well ventilated
area. Do not place anything on the
monitor that prevents adequate
dissipation of heat.
• Ensure the area around the monitor is
clean and free of moisture.
• Keep the monitor away from magnets,
motors, transformers, speakers, and
televisions.

monitor, video cable, or power cord.

odor is present, immediately switch the
monitor off and call your dealer or
ViewSonic. It is dangerous to continue
using the monitor.
