To the dealer and the installer
When installing the projector, please see the Installation Manual pro-
vided on our web site (see the back of the cover).
1. To prevent the projector from falling, install it on the ceiling in a way
with sufficient strength to withstand the combined weight of the
projector and the ceiling mount unit for an extended period of time.
2. When installing the projector on the ceiling, be sure to do so correctly
in accordance with the installation manual for the Ceiling Mount
Unit. Be sure to use the fixed metal fittings and to tighten the screws
securely.
3. To prevent the projector from falling, use fall prevention wires.
• Use commercially available metal fittings to join the robust part
of a building or construction and the security bar of the projector
with the fall prevention wires.
• Use commercially available metal fittings and fall prevention wires
that have sufficient strength to withstand the combined weight of
the projector and the ceiling mount unit.
• Slightly slack off the fall prevention wires so as not to put a load on
the projector.
• Refer to the "Part Names of the Projector" for the location of the
security bar. (→ User's manual)
Securing personal information
Personally identifiable information, such as IP addresses, may be saved
on the projector.
Before transferring or disposing of the projector, clear this data by per-
forming [INITIALIZE PROJECTOR] on the on-screen menu.
Cautions for ensuring the projector's performance
• If intense light like laser beams enters from the lens, it could lead to
malfunction.
• Consult your dealer before using in places where much cigarette
smoke or dust is present.
• When the same still image is projected for a long period of time with
a computer, etc. the pattern of the image may remain on the screen
after the projection is stopped, but it will disappear after a while. This
happens due to the properties of liquid crystal panels, and is not a
malfunction. We recommend using a screensaver on the computer
side.
• When the projector is used at high altitudes (places where the atmo-
spheric pressure is low), it may be necessary to replace the optical
parts sooner than usual.
• About moving the projector
- Detach the lens unit once, and be sure to attach the lens cap so
as not to scratch the lens. Also, attach a dust protective cap to the
projector.
- Do not subject the projector to vibrations or strong shocks.
The projector could be damaged otherwise.
• Do not use the tilt feet for purposes other than adjusting the projec-
tor's tilt.
Improper handling, such as carrying the projector by the tilt feet or
using it leaned against a wall, could lead to malfunction.
• Do not touch the surface of the projection lens with bare hands.
Fingerprints or dirt on the surface of the projection lens will be en-
larged and projected on the screen. Do not touch the surface of the
projection lens.
• Do not unplug the power cord from the projector or the power outlet
while projecting. Doing so could cause deterioration of the projec-
tor's AC IN terminal or power plug contact. To interrupt the AC power
supply while images are being projected, use a breaker, etc.
• About handling of the remote control
- The remote control will not work if the projector's remote signal
sensor or the remote control's signal transmitter is exposed to
strong light or if there are obstacles between them that obstruct
the signals.
- Operate the remote control from within 20 meters from the projec-
tor, pointing it at the projector's remote signal sensor.
- Do not drop the remote control or handle it improperly.
- Do not let water or other liquids get on the remote control. Should
the remote control get wet, wipe it off immediately.
- Avoid using in hot and humid places as far as possible.
• Take measures to prevent external light from shining on the screen.
Make sure only the light from the projector shines on the screen. The
less external light on the screen, the higher the contrast and the more
beautiful the images.
• About screens
Images will not be clear if there is dirt, scratches, discoloration, etc. on
your screen. Handle the screen with care, protecting it from volatile
substances, scratches and dirt.
• Concerning to all maintenance operations, refer to Installation Manual
and follow all instructions properly.
Clearance for Installing the Projector
• When installing the projector, keep sufficient space around it, as
described below. If not, the hot exhaust emitted from the projector
may be taken back in.
Also, make sure no wind from an air-conditioner hits the projector.
The projector's heat control system may detect an abnormality (tem-
perature error) and automatically shut off the power.

NOTE:
• In the above figure, it is assumed that there is sufficient space above the projector.
• When using multiple projectors together, provide sufficient space
around the projectors for air intake and exhaust. When the intake and
exhaust vents are obstructed, the temperature inside the projector
will rise and this may result in a malfunction.
About Copyright of original projected pictures:
Please note that using this projector for the purpose of commercial gain
or the attraction of public attention in a venue such as a coffee shop or
hotel and employing compression or expansion of the screen image
with the following functions may raise concern about the infringement
of copyrights which are protected by copyright law.
[ASPECT RATIO], [KEYSTONE], Magnifying feature and other similar
features.
[AUTO POWER OFF] Function
The factory default setting for [AUTO POWER OFF] is 15 minutes. If no
input signal is received and no operation is performed on the projector
during 15 minutes, the projector is automatically powered off for saving
the power consumption. In order to control the projector by an external
device, set the [AUTO POWER OFF] to [OFF].
