When the projector detects an internal problem, it will shut down automatically and both of the Warning temp. and Ready Indicators starts flashing. In this condition, the projector cannot be turned on even if you press the On/Off button on the remote control unit or on the side control. If this case happenes, disconnect and reconnect the AC power cord, and then turn on the projector again to check its operation. If the projector shuts down again or fails to be turned on, the internal check and repair will be required. Plug off the AC power cord and contact service station.
AIR FILTER CARE AND CLEANING
Air filters help prevent dust from accumulating on the optical elements inside the projector. To whatever extent the air filters become clogged with dust particles, the cooling fans’ effectiveness is reduced, which may result in an internal heat
How often the air filters should be cleaned really depends upon the environment in which the projector is being operated. As a rough guide, under a normally clean operating environment, the air filters should be cleaned approximately every 200 hours of use. However, if the projector is being operated in a somewhat dusty or smoky environment, the air filters should be cleaned more often; for consistently good projector operation and performance, timely cleaning of the air filters is a very important factor. When appropriate, clean the air filters following the steps below.
1 | Turn power off, and disconnect AC power cord from AC outlet. |
2 | Pull out air filter from a projector. |
3 | Pulling up center frame of air filter top, separate air filter top and |
| air filter from air filter base. |
4 | Clean each parts with brush out dust and particles. |
5 | Assemble sheet and air filter and replace air filter to a projector. |
|
|
| CAUTION |
Do not operate a projector with Air Filter removed. Dust may accumulate on LCD Panel and Mirror degrading picture quality.
Do not put small parts into Air Intake Vents. It may result in malfunction of a projector.
