Notes on Handling and Storage

Be sure to observe the following precautions to avoid malfunctions, operating errors or damage to the projector.

Notes on Handling and Storage

• Do not set up the projector near high-voltage electrical wires or sources of magnetic fields.

These may interfere with correct operation.

• Do not touch the lens with bare hands.

If fingerprints or grease get onto the lens, it can interfere with the quality of the projected images. Attach the lens

cover to the lens when the projector is not in use.

• During projection, some points (dots) may appear lit at all times, or they may be dark at all times.

This is caused by the characteristics of the LCD panel, and is not a sign of a malfunction. The LCD panel is

manufactured using extremely high-precision technology. However, black dots may appear on the panel, or some

red, blue or green dots may light extremely brightly at times. Furthermore, sometimes stripe-shaped color

irregularities or brightness irregularities may also appear.

• Remove the batteries from the remote control before storage.

If the batteries are left in the remote control for long periods, they may leak.

• Always attach the lens cap to the lens when not using the projector, to prevent the lens from becoming dirty or

damaged.

• The mercury lamp that is used as the projector's light source deteriorates as a result of normal use and as a

result of impacts or other damage, and may also break with a loud noise, stop working or reach the end of its

service life more quickly.

At such times, the amount of time remaining before the lamp breaks or stops working may vary greatly depending

on the individual lamp characteristics and the operating environment. These are normal characteristics of mercury

lamps. You should always have a spare lamp ready in case it is needed.

• YAMAHA takes no responsibility for loss or damage caused by damage to the projector or operating failures

outside normal service warranty conditions.

Lamp Operating Errors

The mercury lamp that is used as the light source for this projector may stop operating on occasions. This is a normal

characteristic of mercury lamps. If the lamp does not turn on when the projector's power is turned on, remove the

lamp and check if it is broken. If the lamp is not broken, reinstall it. Refer to "Replacing the Lamp" on page 48 of this

manual for instruction on removing and reinstalling the lamp.

If the lamp is broken, replace it with a new lamp. It is recommended that you have a spare lamp ready at all times in

case it is needed.

Notes on Carrying the Projector

• Turn off the projector power and then disconnect the power cord from the electrical outlet.

Furthermore, check that all other cables have been disconnected.

• Attach the lens cap to the lens.

• Retract the adjustable foot.

• If your model of projector has a handle, hold the projector by the handle when carrying it.

Refer to "Lamp operating error" on page 36.

11

Basic Operations

Adjusting the Screen Image

You can adjust the screen image in order to obtain the best possible picture.

The size of the projected image is basically determined by the distance from the projector to the screen.

(Refer to the Setup Guide.)

The following procedures explain how to adjust the screen image once the projector itself has been set up.

Procedure

Turn the zoom ring on the projector to

adjust the image.

The image can be enlarged in this way to 1.35

times the normal size.

If you would like to enlarge the image further,

move the projector further away from the screen.

(Refer to the Setup Guide.)

The projector should be as perpendicular to the screen as possible.

If the projector cannot be set up so that it is exactly perpendicular to the screen, it can be set up so that it is

tilting slightly horizontally or vertically. To tilt the projector upward, adjust the front adjustable foot to tilt

the projector at an angle of up to a maximum 12.9°.

Procedure

Turn the front adjustable foot

underneath the projector to adjust the

projector angle.

Turn the front adjustable foot until the desired

projection angle is obtained.

Adjusting the Image Size

Adjusting the Image Angle

•

••

•

When the foot is adjusted, it may cause the projected images to become distorted. Use the

keystone correction function to adjust this distortion. (p.12)

•

••

•

If the projector is tilted horizontally, turn the rear adjustable feet at left and right to adjust the

horizontal angle.

If the projector is set up so that it is at an angle to the screen, a type of distortion known as "keystone

distortion" may occur.

Keystone correction can be carried out if the angle of the projector is within a range of approximately 15°

vertically from the perpendicular.

Procedure

Correcting Keystone Distortion

•

••

•

When keystone correction is carried out, the projected image will become smaller.

•

••

•

The keystone correction settings are memorized, so that if you change the position or angle of

the projector, you may need to readjust the keystone correction settings.

•

••

•

If the images become uneven in appearance after keystone correction is carried out, decrease

the “Sharpness” setting. (p.27, 29)

•

••

•

Keystone correction can also be carried out using the projector menu. (p.31)

•

••

•

If the value displayed in the gauge on the screen stops changing when horizontal or vertical

keystone correction is being carried out, it indicates that the limit for horizontal or vertical

keystone correction has been exceeded. Check that the projector has not been set up at an

angle which exceeds the proper limit.
