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.
