Before use
Caution when moving the projector
Be sure to attach the lens cover before moving the projector.
The projection lens is extremely susceptible to vibration and shocks. Be
careful not to subject it to excessive vibration and shock when moving the
projector.
Cautions regarding setting-up
Avoid setting up in places which are subject to vibration or shocks.
The internal parts can be damaged, which may cause malfunctions or
accidents.
Do not set up the projector near high-voltage power lines or near
motors.
The projector may be subject to electromagnetic interference.
If installing the projector to the ceiling, ask a qualified technician to
carry out all installation work.
You will need to purchase the separate installation kit (Model No.ET-PK780).
Furthermore, all installation work should only be carried out by a qualified
technician.
If using this projector at high elevations (above 1 400 m), set the “FAN
CONTROL” to “HIGH”. (Refer to page 48.)
Failure to observe this may result in malfunctions.

ENGLISH-11
Preparation
Notes on use
In order to get the best picture quality
raw curtains or blinds over any windows and turn off any lights near the
screen to prevent outside light or light from indoor lamps from shining onto
the screen.
Do not touch the surfaces of the lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints or anything else, this
will be magnified and projected onto the screen. Moreover, when not using
the projector, retract the lens and then cover it with the lens cover.
Screen
o not apply any volatile substances which may cause discoloration to the
screen, and do not let it become dirty or damaged.
Lamp
The lamp may need to be replaced earlier due to variables such as individual
lamp characteristics, usage conditions and the installation environment,
especially when the projector is subjected to continuous use for more than
10 hours or the power is frequently turned on and off, as the operations that
prevent blackening of the bulb (the action of the halogen cycle) do not work
enough during short periods of time.
Liquid crystal panel
The liquid crystal panel of the projector is built with very high precision
technology to provide fine picture details. Occasionally, a few non-active
pixels may appear on the screen as fixed points of blue, green or red.
Please note that this does not affect the performance of your LC .

Connections
Notes on connections
B Read the instruction manual for each peripheral device carefully before connecting it.
B Turn off the power supply for all peripheral devices before making any connections.
B If the cables necessary for connection are not included with the peripheral device or
available as an option, you may need to prepare a proper cable for the device concerned.
B If there is a lot of jitter in the video signal, the projected image may flicker. In such
cases, it will be necessary to connect a TBC (time base corrector).
B Refer to the list on page 70 for details on compatible signals which can be input to
the projector.
B Only one audio system circuit is available for each of the AU IO IN L-R connectors for
S-VI EO/VI EO signals and the RGB AU IO IN connector, so if you wish to change
the audio input source, you will need to remove and insert the appropriate plugs.
