Important safety instructions Your projector is designed and tested to meet the latest standards for safety of information technology equipment. However, to ensure safe use of this product, it is important that you follow the instructions mentioned in this manual and marked on the product. Safety Instructions 1. Please read this manual before you operate your projector. Save it for future reference. 2. Do not look straight at the projector lens during operation. The intense light beam may damage your eyes. 3. Refer servicing to qualified service personnel. 4. Always open the lens shutter or remove the lens cap when the projector light source is on. 5. In some countries, the line voltage is NOT stable. This projector is designed to operate safely within a mains voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10 volts occur. In areas where the mains voltage may fluctuate or cut out, it is recommended that you connect your projector through a power stabilizer, surge protector or uninterruptible power supply (UPS). 6. Do not block the projection lens with any objects when the projector is under operation as this could cause the objects to become heated and deformed or even cause a fire. To temporarily turn off the light source, press BLANK on the projector or remote control. 7. Do not operate light sources beyond the rated light source life. Excessive operation of light sources beyond the rated life could cause them to break on rare occasions. 8. Never replace the light source assembly or any electronic components unless the projector is unplugged. 9. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining serious damage. 10. Do not attempt to disassemble this projector. There are dangerous high voltages inside which may cause death if you should come into contact with live parts. The only user serviceable part is the light source which has its own removable cover. Under no circumstances should you ever undo or remove any other covers. Refer servicing only to suitably qualified professional service personnel. 11. Do not place this projector in any of the following environments. - Space that is poorly ventilated or confined. Allow at least 50 cm clearance from walls and free flow of air around the projector. - Locations where temperatures may become excessively high, such as the inside of a car with all windows rolled up. - Locations where excessive humidity, dust, or cigarette smoke may contaminate optical components, shortening the projector's life span and darkening the picture. - Locations near fire alarms - Locations with an ambient temperature above 40°C / 104°F - Locations where the altitudes are higher than 3000 m (10000 feet). 2
