Setting up your projector

Setting up the screen

Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the projection angle of the projector. (See below.)

•Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of the screen center.

•Do not install the screen where it is exposed to direct sunlight or lighting. Light directly reflecting on the screen makes the projected images whitish and hard to view.

Basic setup

Determine the distance from the screen to the projector according to the size of the images to be projected. (See page 11.)

•Do not place this projector on a carpet or blanket because the exhaust vent and the intake vent on the bottom surface are blocked and the inside of the projector is heated, causing a breakdown or fire.

•Depending on the installation conditions, warm air that is emitted from the exhaust vents may flow into the intake vent, causing the projector to display “TEMPERATURE!!” and then stop projecting images.

Adjusting the projection angle

This projector is provided with 3 feet for adjusting the projection angle on the bottom surface. Adjust the projection angle depending on the position of the projector.

Adjustment of the projection angle

For the best projection, project images on a flat screen installed at 90 degrees to the floor. If necessary, tilt the projector using 2 adjustment feet on the bottom of the projector.

•You can correct the vertical and horizontal key- stones at the same time. However, their adjust- ment ranges are limited in such correction.

•When the keystone adjustment is carried out, the adjustment value is indicated. Note that this value doesn't mean a projection angle.

•The allowable range of the adjustment value in the keystone adjustment varies depending on the installation conditions.

•When the keystone adjustment takes effect, the resolution decreases. In addition, stripes may appear or straight lines may bend in images with complicated patterns. They are not due to product malfunctions.

•Noise may appear on the screen during the key- stone adjustment because of the type of the video signal being projected and the setting values of the keystone adjustment. In such cases, set the keystone adjustment values in the range where the image is displayed without noise.

•When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of input signal.

•Displayed image may be distorted during keystone adjustment.
