Mounting the projector
If you intend to mount your projector, we strongly recommend that you use a projector ceiling
mount kit and that you ensure it is securely and safely installed.
Before mounting the projector
• Ask your dealer to install the projector for you. Installing the projector on your own may cause
it to fall and result in injury.
• Take necessary procedures to prevent the projector from falling off such as during an
earthquake.
• The warranty on this projector does not cover any damage caused by installation of the ceiling
mount kit in an improper location.
• Consider the surrounding temperature where the projector is ceiling mounted. If a heater is
used, the temperature around the ceiling may be higher than expected.
• Read the user’s guide for the mounting kit about the range of torque. Tightening with torque
exceeding the recommended range may cause damage to the projector and subsequently
falling off.
• Make sure the power outlet is at an accessible height so that you can easily shut down the
projector.
Be sure to stop turning the adjustment knob when you hear a clicking sound indicating that the knob has
reached its limit. Over-turning the knob may cause damage.
