z After the Projector System is installed, never
loosen any of its bolts, screws, or nuts.
Adjustment by non-specialists creates the risk
of the bracket and projector falling down.
z Should you ever notice any part or component
has fallen from the bracket/projector,
immediately check the installation.
z Never allow anything to be hung from the
bracket. Doing so creates the risk of the bracket
and projector falling down and other problems.
z After installation is complete, leave all
maintenance work up to qualified specialists.
z For information about projector maintenance,
see the projector user’s guide.
z Do not place heavy objects on the projector or
wall mount bracket, and do not allow anyone to
climb onto them.
z Make sure that the installation does not result in
blocking of the projector’s intake and exhaust
vents. Periodically check the projector to ensure
that its intake and exhaust vents are note
clogged by dust build-up. Should dust build up,
clean the vents before using the projector.
z When installing up and adjusting the wall mount
bracket, take care to avoid pinching your hands
between metal parts.
z Never use any type of screws except for those
that are specified. Use of non-specified screws
creates the risk of the projector falling down and
other problems.
z Never try to modify the wall mount bracket in
any way. (The strength of modified bracket
cannot be guaranteed.)
Installation Location
Precautions
z Never install this product in any of the types of
locations below.
z When installing a projector, keep it away from
fluorescent lighting, air conditioning, and other
electrical devices. Some fluorescent lighting can
interfere with operation of the projector’s remote
control system.
z Make sure that the projector’s power key is
located in a position where it can be used to turn
off the projector in order recover from projector
operation errors, to protect internal circuitry, and
to save energy.
z In order to ensure noise-free projection images,
use of a cable no more than 10 meters long is
recommended when connecting a computer or
other device. Also, keep the connecting cable
away from the AC cord.
z In order to avoid soiling of the lens and internal
light source, install the projector in a location
where there is little chance of exposure to dust
and moisture.
z When direct sunlight is shining into the room,
the projection image can be made easier to see
by drawing curtains over windows.
z Light and heat emitted by the projector may
cause discoloration of its surroundings.
z Avoid mounting at a height that allows the
projector to be touched by people. If a relatively
low installation position is unavoidable, take
care to install in a way that avoids head and
other injury.
z Make sure that the projection side of the
projector is at least 6 cm (2.4 inches) from the
projection surface (wall), and all other sides are
at least 30 cm (11.8 inches) from surrounding
surfaces. There should be no other objects
within the above distances from the projector.
Warning
z This product does not have rotary angle
adjustment. After adjusting the elevation
and angle, never rotate the projector
while the screws are tightened. After
installation is complete, leave all
elevation and angle adjustments up to
qualified specialists. Adjustment by
non-specialists creates the risk of the
bracket and projector falling down.
