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. 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
deformed or even cause a fire.
