Be sure to observe the following instructions when installing an LCD projector.
1. Make sure the table is sturdy enough to support the weight of the projector and the tabletop use kit.
LCD projector Approx. 4.1 kg
Tabletop use kit (TT-251) Approx. 3.5 kg
2. If the temperature inside the LCD projector gets too high, the temperature sensor will activate and turn off the
projector to prevent damage. Do the following to avoid an abnormally high temperature.
(1) Select a location where the ambient temperature is in the range of 5 to 35°C.
(2) Periodically clean the projector’s air intake lter. For details on how often and how to clean the lter, see the
LCD Projector Users Manual.
(3) In a dusty location, the lter will need more frequent cleaning than in (2) above so install the projector in a
location where cleaning is easy.
(4) Leave 30 cm or more space on the sides of the LCD projector to allow the free ow of air from the exhaust and
leave 10 mm or more space at the back of the projector to enable air to enter via the air intake.
(5) Do not install the projector in a location exposed to sudden temperature changes, for example near air
conditioners, or where the temperature rises above 35°C.
3. Do not install the projector in a smoke-lled or extremely dusty environment as the tar in cigarette smoke will
settle on the optics and lower performance.
4. Do not install the projector in a location where the remote control sensor will be exposed to direct sunlight, other
strong light sources or inverter uorescent lamp light at close range to prevent remote control malfunction.
Installation Precautions
This tabletop use kit is designed to install a Hitachi LCD projector on top of a table and to project images on the
surface of the table.
Supported Hitachi LCD projector models: CP-AW251N (CP-AW251NM)
CP-A221N (CP-A221NM)

WARNING
■ Do not install the projector in a location exposed to high humidity, dust or tobacco smoke or in a
location exposed to smoke or steam.
■ Do not install the projector in a location exposed to vibrations.
■ After you have nished installation, keep this manual and accessories in a safe place for future
reference.
Small parts such as adjusting screws could be swallowed by small children and pets should be kept
away. If your child swallows any small parts, consult a doctor immediately.
■ Perform all installation work correctly according to this manual. Make sure that all specied screws
and brackets are used in the installation.
Make sure the installation place is sturdy enough to support the weight of the projector and the
tabletop use kit.
Never attempt to modify the tabletop use kit. (We will not guarantee the strength of a unit that has
been modied.)
■ Make sure that all screws are tightened to the proper torque after installation and adjustments. There
must be no loose or over tightened screws.
Do not apply thread-locking uid, lubricants, lubricating oils or other chemicals designed to prevent
loosening of fasteners on screws and bolts used to secure the projector and tabletop use kit. Using
such a materials could cause the projector to fall, resulting in damage or injury.
■ Route electric cables as prescribed and take care not to damage them in the installation work.
■ Be sure to read this manual and the User’s Manual of the LCD projector prior to installation to
ensure that all safety instructions are observed and the projector is correctly installed.
■ Be sure to turn off the LCD projector and disconnect the power plug from the wall outlet before
starting installation work.
Do not lean against the projector or tabletop use kit. The projector may fall or the tabletop use kit
may bend, resulting in damage or injury.
Keep the table flat while installing the tabletop use kit. Performing the installation on a slanted
surface may cause the unit to fall or the lamp life to shorten.
Do not install the tabletop use kit in unstable places. The projector or tabletop use kit may fall and
break, resulting in damage or injury.
Do not use screws that are not included in this package or in places that are not specied in this
manual.
Routine Inspections
Like the projector, the tabletop use kit should be inspected once a year.
1. Check that the screws of the tabletop use kit and adjusting parts are not loose.
2. Check that the tabletop use kit, adjusting parts and the set are not scratched or damaged.
NOTE
The image on the table might be distorted if the projection surface is bent, so use it on a at surface.
Using the PERFECT FIT may cause the image quality to deteriorate, so use the tabletop use kit for adjustments
of distortions as much as possible. See the User's manual of the projector on how to operate the PERFECT FIT.
