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.

Safety Instructions (Continued)
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. 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.

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 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).
14. 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. 
- Do not place inflammables near the 
projector.

obstructed, overheating inside the 
projector may result in a fire.
15. 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.
