a malfunction.
•
The microcomputers inside the projector may be wrongly operating because of noise.

power cord from the wall outlet. Wait about 10 minutes, plug the power cord in, and try
again.
•
You cannot select (or set) grayed-out items. Whether items can be selected or not
depends on the presence of an input signal at the time when the menu is displayed, the
type of such input signal, and other conditions.
•
This indication appears when the ambient temperature rises high. When the ambient
temperature stays high, the lamp goes out.
→ Eliminate any causes of the rise in the ambient temperature.
•
This indication appears when the intake or exhaust vents are blocked. When they are
kept blocked, the lamp goes out.
→ Remove the objects blocking the intake or exhaust vents.
This mark appears when ineffective operation is carried out. This isn't a product malfunction.
