Make sure the followings when you install and handle the ceiling attachment.
● Make sure to ask a specialist or sales office if you want to install the ceiling attachment.
An inappropriate installation may cause an accident.
● During projection, never put an object in front of the projector's lens
(projection window).
● Be sure to install the attachment to a vertical wall. Do not install it to a sloping wall.
If this is not observed, accidents or operating problems may occur.
● When using the wall attachment to install the projector to a wall, make sure that the wall is
strong enough to support the combined weight of the projector and the wall attachment.
Before carrying out installation, check the weight of the projector and the weight of
the wall attachment, and then check the strength of the wall. If the wall is not strong
enough, provide it with sufficient reinforcement.
If this is not done, the projector may fall down and injury may occur.
● When installing the projector, take appropriate measures using wire or other means to
prevent falling due to an earthquake or other vibration. Otherwise, the projector may fall,
causing injury.
● Be sure to install the ceiling attachment so that there is at least 50 cm between the
projector's air intake vent and the wall, and at least 1 m between the air exhaust vent
and the wall.
● Use a flat, stable surface as the screen. In addition, if projecting onto a wall or similar
surface, the images may not be projected correctly if the wall is uneven or curved.
