4 Important safety instructions
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.
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 (if any) or
remove the lens cap (if any) when the
projector light source is on.
5. The light source becomes extremely hot
during operation.
6. 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).
7. 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, use the blank function.
8. Do not operate light sources beyond the
rated light source life.
