• Keep a space of 30 cm or more between the sides of the projector and other
objects such as walls.
• For the case of installation in a special state such as ceiling mount, the
specified mounting accessories (
64) and service may be required. Before
installing the projector, consult your dealer about your installation.
• The screen position may shift after installation if the projector is suspended
from the ceiling or other location due to the flexibility of the plastic projector
body. If readjustment is necessary, consult with your dealer or service
personnel.
• The projected image position and/or focus may change during warm-
up (approx. 30 minutes after the lamp is turned on) or when the ambient
conditions change. Readjust the image position and/or focus as necessary.
