5 Important safety instructions
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 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.
If the ventilation holes are seriously
obstructed, overheating inside the projector
may result in a fire.
13. 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.
14. 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.
15. 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.
16. 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.
