If the projector is suddenly taken from a cold environment
to a warm environment, 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 in which it
is to be used approximately one hour before use. If
condensation forms on the lens, turn off the power and
wait for the condensation to disappear.
Turn the focus ring to adjust the focus.
If using an extension cable, electrical interference may
affect the signals.
Check that the cables are securely connected.
Interference may occur if the cables are not connected
securely.
Press the [Aspect] button to change the aspect ratio.
s "Changing aspect ratio" Quick Reference Guide
Use the "Setting" → "Screen" → "Position"
configuration menu to correctly adjust the display
position.
When the lamp is due for replacement, colours will
weaken and the image will become dark. Replace the lamp
