CLEANING THE LENS
Follow these steps to clean the projection lens:
1. Apply a non-abrasive camera lens cleaner to a soft, dry cleaning cloth.
Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents or other harsh chemicals might scratch the lens.
2. Lightly wipe the cleaning cloth over the lens.
3. If you don't intend to use the projector immediately, replace the lens cover.
Before calling your dealer or service station for assistance, follow these steps, to make sure everything is properly connected.
1. Make sure you have connected the projector to your equipment as described in section "CONNECTING THE
PROJECTOR" on pages 14 ~ 21.
2. Check cable connections. Verify that all computer, video and power cords are properly connected.
3. Verify that power is switched on.
4. If the projector still does not display an image, restart the computer.
5. If the image still does not display, unplug the projector from the computer and check the computer monitor's display. The
problem may be with your graphics controller rather than with the projector. (When you reconnect the projector, remember
to turn the computer and monitor off before you power up the projector. Power the equipment back up in this order:
Projector, monitor, computer)
6. If the problem still exists, check the following chart.
