• When connecting to a power outlet, DO NOT remove the grounding prong.
Please ensure grounding prongs are NEVER REMOVED.
• Protect the power cord from being treaded upon or pinched, particularly at the
plug, and at the point where it emerges from the projector.
• In some countries, the voltage is NOT stable. This projector is designed to
operate safely within a voltage between 100 to 240 volts DC, but could fail if
power cuts or surges of ±10 volts occur. In areas where voltage may fluctuate
or cut out, it is recommended that you connect your projector through a power
stabilizer, surge protector, or uninterruptable power supply (UPS).
• If smoke, an abnormal noise, or a strange odor is present, immediately switch
the projector off and call your dealer or ViewSonic®. It is dangerous to continue
using the projector.
• Use only attachments/accessories specified by the manufacturer.
• Disconnect the power cord from the DC outlet if the projector is not being used
for a long period of time.
• Refer all servicing to qualified service personnel.
