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 lamp 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 lamp, press BLANK on the projector or 
remote control.
7. The lamp becomes extremely hot during operation. Allow the projector to cool for 
approximately 45 minutes prior to removing the lamp assembly for replacement. 
8. Do not operate lamps beyond the rated lamp life. Excessive operation of lamps 
beyond the rated life could cause them to break on rare occasions. 
9. Never replace the lamp assembly or any electronic components unless the projector is 
unplugged. 
10. Do not place this product on an unstable cart, stand, or table. The product may fall, 
sustaining serious damage. 
11. 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 lamp 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.
12. 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 projectors 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).

13. Do not block the ventilation holes. If the ventilation holes are seriously obstructed, 
overheating inside the projector may result in a fire.
-  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. 
-  Do not place inflammables near the projector.   
14. Always place the projector on a level, horizontal surface during operation.
-  Do not use if tilted at an angle of more than 10 degrees left to right, nor at angle of 
more than 15 degrees front to back. Using the projector when it is not fully horizontal 
may cause a malfunction of, or damage to, the lamp.
15. Do not stand the projector on end vertically. Doing so may cause the projector to fall 
over, causing injury or resulting in damage to the projector.
16. Do not step on the projector or place any objects upon it. Besides probable physical 
damage to the projector, doing so may result in accidents and possible injury.
17. Do not place liquids near or on the projector. Liquids spilled into the projector may 
cause it to fail. If the projector does become wet, disconnect it from the power 
supplys wall socket and call your local service center to have the projector serviced.
18. This product is capable of displaying inverted pictures for ceiling mount installation. 
Use only qualified ceiling mount kit for mounting the projector and ensure it is 
securely installed. 
19. When the projector is under operation, you may sense some heated air and odor from 
its ventilation grill. It is a normal phenomenon and not a product defect.
20. Do not use the Security bar for transporting or installation. It should be used with a 
commercially available theft prevention cable. 
Safety instructions for ceiling mounting of the 
projector
We want you to have a pleasant experience using your projector, so we need to bring this 
safety matter to your attention to prevent damage to person and property.
If you intend to mount your projector on the ceiling, we strongly recommend that you use a 
proper fitting projector ceiling mount kit and that you ensure it is securely and safely 
installed.
If you use an inappropriate projector ceiling mount kit, there is a safety risk that the 
projector may fall from the ceiling due to an improper attachment through the use of the 
wrong gauge or length screws.
You can purchase a projector ceiling mount kit from the place you purchased your projector. 
We recommends that you also purchase a separate Kensington lock compatible security 
cable and attach it securely to both the Kensington lock slot on the projector and the base of 
the ceiling mount bracket. This will perform the secondary role of restraining the projector 
should its attachment to the mounting bracket become loose.

• The apparent brightness of the projected image will vary depending on the ambient 
lighting conditions, selected input signal contrast/brightness settings, and is directly 
proportional to projection distance.
• The lamp brightness will decline over time and may vary within the lamp manufacturers 
specifications. This is normal and expected behavior.
