Check the recommended projection range.
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.
Check that all the cables required for projection are securely
connected. p.19
s
If an extension cable is used, electrical interference may affect
the signals.
The projector uses automatic adjustment functions to project at
the optimum status. However, depending on the signal, some
may not be adjusted correctly even after performing self correc-
tions. If this happens, adjust the Tracking and Sync. settings
from the Configuration menu.
Set the computer so that the signals being output are compatible
with the projector. p.96
s
Select the aspect mode to match the input signal in Aspect from
the Configuration menu.
