SAFETY INSTRUCTIONS

1. Always follow the instructions set forth in this manual when installing the projector
using this bracket.

Improper or inadequate installation could cause the projector to fall and injure someone.

2. The installation must be secure enough to bear the weight of the projector, the ceiling
bracket, and other hardware indefinitely, and must also be secure enough to withstand
vibration.

Inadequate installation could cause the projector to fall and injure someone.

3. To ensure safety, all bolts and screws must be tightened securely.

Loose bolts or screws could cause the projector to fall and injure someone.

4. Use only the parts provided with the bracket, and any other parts (commrecially
available) that are specified in this manual.

Using other parts could cause the projector to fall and injure someone.

5. Do not modify the bracket or the parts provided with the bracket.

Modifying the bracket or the other parts could cause the projector to fall and injure someone.

6. Do not use damaged parts.

7. Make sure to leave enough open space around the unit to allow heat generated by the
projector to dissipate.

Failure to provide adequate space around the unit could cause the projector to overheat internally, causing a
fire.

8. Before replacing the lamp cartridge, always remove the projector (with the mounting
adapter attached) from the ceiling bracket.

Attempting to replace the lamp cartridge while the projector is attached to the ceiling bracket could cause
the projector or the ceiling bracket to fall and injure someone.

9. Never hang from the projector or the ceiling bracket.

Hanging from the projector or the ceiling bracket could cause the projector or the ceiling bracket to fall and
injure someone.

10. Do not install the projector in a location near an air conditioning vent or in a location
subject to vibration.

Such conditions could have an adverse effect on the projector, and could even cause a fire or electric shock.

11. Do not install the projector in a location that is subject to high levels of dust or
humidity.

Dust accumulating inside the projector could cause a short circuit that in turn could cause a fire or electric
shock.

12. Do not install the projector in a location that is exposed to direct sunlight or in a
location that is subject to extreme fluctuations in temperature (such as near an air
conditioner).

Such conditions can cause the projector housing to warp or to become discolored.

13. Do not wipe the exterior of the ceiling bracket with benzene, paint thinner or cleaning
compounds.

Doing so could damage the finish.

14. Special techniques and experience are essential when installing the projector using
this bracket. Request that your dealer arrange to have the equipment installed. The
customer should never attempt to suspend the projector from the ceiling.

Improper installation could cause the ceiling bracket or the projector to fall and injure someone.

15. Once the projector is installed, safety checks should be conducted on a regular basis.

If the projector is used over an extended period of time, screws can become loose and the installation can
become weaker due to the passage of time, vibration, etc.
