Setting up

Adjusting the projection size

The size of the projected image is basically determined by the distance from the projector's lens

to the screen. Adjustment the projection size

Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet before installing the projector.

Do not stand this projector upright. This may damage your projector.

Lens shift adjustment

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.

*You cannot shift the image by the full amount both vertically and horizontally.

Ex) When the image is shifted horizontally by the full amount, it cannot be shifted vertically by more than 36 % of its height.

And when the image is shifted vertically by the full amount, it cannot be shifted horizontally by more than 17 % of its width.

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.

*2 Some regions may not have the RGB SCART adapter included as an accessory.

•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 > S-Video > Composite 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".

12

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.

Close the battery cover.

Press the battery compartment cover until it clicks into place.

Battery replacement period

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.
