Important Notes
1. The projector uses a high-pressure mercury glass lamp. The lamp can
break with a loud bang, or turn out, if jolted or scratched, handled while
hot, or worn over time. Note that each lamp has a different lifetime, and
some may burst or burn out soon after you start using them.
2. Always open the lens shutter or remove lens cap when the projection
lamp is on.
3. To avoid premature lamp failure, do not change the mounting position
of the projector (desktop ceiling mount or ceiling desktop mount) and
continue to use the same lamp.
4. To avoid reduced lamp life, do not touch projection lamp with bare
fingers.
5. To avoid reduced image quality, do not touch projection lens or other
internal optical components.
6. Do not use detergents, chemicals, or any spray liquids for cleaning this
unit, other than those referred to in the “Operators Guide”.
7. For maximum lamp life, do not strike or drop, improperly handle, or
scratch the lamp glass. Also, do not install an old or used lamp.
8. Keep air filter clean. Refer to the cleaning instructions contained in the
“Operator’s Guide”.
9. Keep all ventilation openings free of any obstructions.
10. In some countries, the line voltage is NOT stable. This projector is
designed to operate safely within a bandwidth of 100–240 V AC (50 to
60 Hz), but could fail if power drops or surges of ±10 volts occur. In these
high-risk areas, it is recommended to install a power stabilizer unit.
