• 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. CAUTION: Possibly hazardous optical radiation is emitted from this product. As with any bright light source, do not stare into the beam, RG2 IEC 624715:2015. Additional warning against eye exposure for close exposures less than 1 m. 4
