Image problems
•
If the searching source is displayed:
•
Press SOURCE to select an active input source.
•
Be sure the external source is turned on and
connected.
•
For a computer connection, ensure your
notebook computer’s external video port is
turned on. Refer to the computer manual.
•
If the image is out of focus:
•
While displaying the on-screen menu, adjust
the focus ring. (The image size should not
change; if it does, you are adjusting the zoom,
not the focus.)
•
Check the projection lens to see if it needs
cleaning.
•
If the image is flickering or unstable for a computer
connection:
•
Press RESYNC.

Remote control
problems
•
If the remote control does not operate:
•
Be sure nothing is blocking the remote control
receiver on the front of the projector.
•
Use the remote control within the effective range.
•
Aim the remote control at the screen or at the
front of the projector.
•
Move the remote control so it is more directly
in front of or behind the projector and not as
far to the side.
