Safety instructions (continued)
5. Do not block the ventilation holes whilst the
projector is on (even in standby mode):
- Do not cover the projector with any item;
- Do not place the projector on a blanket, bedding
or any other soft surface.
6. In areas where the mains power supply voltage
may fluctuate by
±10 volts, it is recommended
that you connect your projector through a power
stabilizer, surge protector or uninterruptible
power supply (UPS) as appropriate to your
situation.
7. Do not step on the projector or place any objects
upon it.
8. Do not place liquids near or on the projector.
Liquids spilled into the projector will void your
warranty. If the projector does become wet,
disconnect it from the power point and call BenQ
to have the projector repaired.
9. Do not look straight into the projector lens during
operation. It may harm your sight.
10. Do not operate the projector lamp beyond the
rated lamp life. Excessive operation of lamps
beyond the rated life could cause a lamp to break
on rare occasions.
11. The lamp becomes extremely hot during
operation. Allow the projector to cool for
approximately 45 minutes prior to removing the
lamp assembly for replacement.
