The optimum images for the location can be projected simply by selecting the desired colour mode from the following six preset modes. No complex colour adjustments are required. If "Natural", "Theatre", "Theatre Black 1" or "Theatre Black 2" is selected, the Epson Cinema Filter effect is applied automatically to increase the contrast and to make skin tones appear with more natural tints. p.18

In addition to the "Color Mode", the "Color Temp." and "Skin Tone" can be adjusted by simple procedures to render the picture even more to your own liking. "Color Temp." can be adjusted to obtain "warm" or "cold" hues for the entire picture's colours. The skin tones of people in the picture are adjusted to natural shades by the Epson Cinema Filter, but can be further adjusted according to taste by means of the "Skin Tone" feature. p.20

Lens shift adjustment

The lens shift dials can be used to position the image and is especially useful when using the projector in the following locations. p.16

Hanging from the ceiling A screen in a high location Projector situated to the side so that the screen can be viewd sitting right in front of it Projector situated on a shelf, etc.

When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens shift correction is adjusted optically.

Installing the Projector

Avoid setting the projector up in places which are very dusty such as bedrooms. Clean the air filter at least once every 3 months.

TIP

Clean the air filter more frequently if using the projector in a dusty environment. When installing against a wall, leave a space of 20 cm (7.9 in.) or more between the projector

and the wall. A special method of installation is required in order to suspend the projector from the ceiling.

Please contact your dealer if you would like to use this installation method.

Connecting Image Sources

•Turn the power off for both the projector and the signal source before connecting them.

If the power for either device is on at the time of connection, damage may result.

•Check the shapes of the cable connectors and the device ports before making the

connections. If you try to force a connector to fit a device port with a different shape or number of terminals, a malfunction or damage to the connector or port may result.

•Some signal sources may have specially-shaped ports. In such cases, use the accessory or

optional cables that are supplied with the signal source to make the connections.

TIP

•The cable that should be used to connect video equipment to the projector will depend on

the type of video signal that the equipment outputs. Some kinds of video equipment output several different types of video signal. The image quality ranking of the video signal types is generally held to be as follows, in descending order of quality: Component video You should refer to the documentation provided with the video equipment being used to check what types of video signal formats the equipment can output. The composite video format is sometimes simply called "video output".

Preparing the Remote Control

Inserting batteries into the remote control

The remote control is not supplied with batteries already inserted. Insert the accessory batteries before using the remote control.

Open the battery cover.

While pressing the knob, lift up.

Insert the batteries.

Check the (+) and (-) indications inside the battery compartment and insert the batteries so that they face correctly.

Battery replacement period

Close the battery cover.

Press the battery compartment cover until it clicks into place.

Installing the Projector

If delays in the responsiveness of the remote control occur or if it does not operate after it has been used for some time, it probably means that the batteries are becoming flat. If this happens, replace the batteries with two new batteries. Use two new AA batteries as replacement batteries.
