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.

13

Preparation

About the screen

If the screen you are using is dirty, damaged or discolored, attractive

projections cannot be obtained. Do not apply any volatile substances 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 a

particular lamp’s characteristics, usage conditions and the installation

environment, especially when it is subjected to a continuous use for more

than 10 hours.

About the SD memory card (PT-L780NTU only)

Static electricity from the human body can damage the SD memory card. To

prevent this, you should touch a nearby metallic object such as an aluminium

sash or a door knob to dissipate the static charge from your body.

About the card slot (PT-L780NTU only)

Make sure that there are no foreign objects inside the slot when inserting the

SD memory card or an optional wireless card. Failure to observe it may

damage the card and the slot.

Before carrying out cleaning and maintenance, be

sure to disconnect the power cord plug from the

wall outlet.

Wipe the cabinet with a soft, dry cloth.

If the cabinet is particularly dirty, soak the cloth in water with a small amount

of neutral detergent in it, squeeze the cloth very well, and then wipe the

cabinet. After cleaning, wipe the cabinet dry with a dry cloth.

If using a chemically-treated cloth, read the instructions supplied with

the cloth before use.

Do not wipe the lens with a cloth that is dusty or which produces lint.

If any dust or lint gets onto the lens, such dust or lint will be magnified and

projected onto the screen. Use a blower to clean any dust and lint from the

lens surface, or use a soft cloth to wipe off any dust or lint.
