Notes on use
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off any
fluorescent 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 accessory lens cover.
About the screen
Do not apply any volatile substances which may cause
discolouration to the screen, and do not let it become dirty or
damaged.
About the 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.
Before use
Cautions 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. When moving the projector, use the accessory
carrying bag. When placing the projector inside the carrying
bag, position it so that the lens is facing upward.
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-PKC80). Furthermore, all installation work should only
be carried out by a qualified technician.
If using this projector at high elevations (above 1400 m),
set the FAN CONTROL to HIGH. (Refer to page 43.)

Connections
Notes on connections
B
Read the instruction manual for each system component carefully before connecting it.
B
Turn off the power supply for all components before making any connections.
B
If the cables necessary for connecting a component to the system are not included with the component
or available as an option, you may need to fashion a cable to suit the component concerned.
B
If there is a lot of jitter in the video signal which is input from the video source, the picture on the
screen may flicker. In such cases, it will be necessary to connect a TBC (time base corrector).
B Refer to the list on page 58 for details on compatible signals which can be
input to the projector.
B
Only one audio system circuit is available for the AUDIO IN L-R jacks, so if you wish to
change the audio input source, you will need to remove and insert the appropriate plugs.
