Precautions on handling
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. Be
careful not to subject it to excessive vibration and shock when moving the
projector.
Cautions regarding setting-up
Observe the following at all times when setting up the projector.
Avoid setting up in places which are subject to vibration or shocks.
If the projector is set up in locations with strong vibration, such as near a
motor, or if it is installed inside a vehicle or on board a ship, the projector
may be subjected to vibration or shocks which can damage the internal parts
and cause malfunctions or accidents. Accordingly, set up the projector in a
place which is free from such vibrations and shocks.
Do not set up the projector near high-voltage power lines or near
motors.
The projector may be subject to electromagnetic interference if it is set up
near high-voltage power lines or motors.
If installing the projector to the ceiling, ask a qualified technician to
carry out all installation work.
If the projector is to be suspended from the ceiling, 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 47.)
Failure to observe this may result in malfunctions.
Notes on use
In order to get the best picture quality
If outside light or light from indoor lamps is shining onto the screen, the
images projected will not have good contrast. Draw curtains or blinds over
any windows and turn off any fluorescent lights near the screen to prevent
reflection.
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.
