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.
General safety instruction
1. Do not look straight at the projector lens during operation. The intense light beam may
damage your eyes.
2. Always open the lens shutter or remove the lens cap when the projector light source is on.
3. 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).
4. 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 remote control.
5. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining
serious damage.
6. 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.
Under no circumstances should you ever undo or remove any other covers. Refer servicing
only to suitably qualified professional service personnel.
7. 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 image.
• 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).
8. Do not block the ventilation holes.
• Do not place this projector on a blanket, bedding or any other soft surface.
• Do not cover this projector with a cloth or any other item.
