Placement
WARNING
• Always obey the instructions listed in IMPORTANT SAFETY INSTRUCTIONS when placing the unit.
Attempting to clean/replace the lamp at a high site by yourself may cause you to drop down, thus
resulting in injury.
• If you wish to mount the projector on the ceiling, be sure to ask your dealer to do so. Mounting the
projector on a ceiling requires special ceiling brackets (sold separately) and specialized knowledge.
Improper mounting could cause the projector to fall, resulting in an accident.
• If the projector is ceiling-mounted, install the breaker for turning off the power in case of anomaly. Let
everyone involved with the use of the projector know that fact.
