nected to the proper port. If the device is not connected prop-
erly, it can not be selected.
Menu and
Remote
Control
Remote control does not work. Be sure that the proper external source is selected.
Check the remote control battery. If there is something wrong
with it, replace it with a new battery of the recommended size.
Be sure to aim the remote at sensor on the back of the unit and
at a distance of no more than approximately 23 feet(7 m).
Remove any obstacles between your remote control and the
product.
Direct light from 3-way light bulbs or other lighting devices on
the remote sensor of the projector may affect the sensitivity
and cause the remote control to malfunction.
Check if the remote control battery compartment is empty.
Check whether the LED indicator on the top of the projector is
turned on.
I cannot select a menu. Check if the menu is displayed in gray. A gray-colored menu is
unavailable.
