Turn on the device.
(Only when projecting computer image sig-
nals)
Are the image signals being output to the
projector?
Change it so that the image signal is set to external output, and
not just the computer's LCD monitor. For some models, when
the image signals are output externally, they no longer appear
on the LCD monitor.
For the computer's specifications, see the documentation sup-
plied with the computer.
If the connection is made while the power of the projector or the
computer is already turned on, the Fn key (Function key) that
changes the computer's image signal to external output may not
work. Turn off the power for the computer and the projector and
then back on again.
Keystone distortion of projected image
Check
Remedy
Is keystone distortion adjusted within the cor-
rection range?
If projecting the image from outside of the correctable range,
you may not be able to correct the keystone distortion com-
pletely. Install the projector horizontally in front of the screen
and parallel to the screen as much as possible, and then adjust
the projection position using lens shift.
s
Images are fuzzy or out of focus
Check
Remedy
Has the focus been adjusted?
Adjust the focus.
s
Is the lens cover closed?
Open the lens cover.
Is the projector at the correct distance?
Check the recommended projection range.
s
Has condensation formed on the lens?
If the projector is suddenly taken from a cold environment to a
warm environment, or if sudden ambient temperature changes
occur, condensation may form on the surface of the lens, and this
may cause the images to appear fuzzy. Set the projector up in
the room about one hour before it is used. If the projector is wet
from condensation, turn off the projector, disconnect the power
cord, and leave it for a while.
