you follow the instructions mentioned in this manual and marked on the product.

Safety Instructions

1. Please read this manual before

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. In some countries, the line voltage is

NOT stable. This projector is

designed to operate safely within a

mains voltage of 19 volts DC, 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).

5. 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

death if you should come into

contact with live parts. Refer

servicing only to suitably qualified

professional service personnel.

9. When the projector is under

heated air and odor from its

ventilation grill. It is a normal

defect.

10. Do not place this projector in any

of the following environments.

dust, or cigarette smoke may

contaminate optical components,

shortening the projector's life span

and darkening the image.

Important safety instructions 5

Safety Instructions (Continued)
