Operation 25

7. The projector will start to search for input signals. The current input signal being

scanned displays in the screen. If the projector doesn't detect a valid signal, the

message 'No Signal' will continue displaying until an input signal is found.

You can also press SOURCE on the projector or remote control to select your

desired input signal. See "Switching input signal" on page 33 for details.

• If no signal is detected for 3 minutes, the projector automatically enters ECO

BLANK mode.

Adjusting the projected image

Adjusting the projection angle

The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot.

These adjusters change the image height and projection angle. To adjust the projector:

1. Press the quick-release button and lift the

front of the projector. Once the image is

positioned where you want it, release the

quick-release button to lock the foot in

position.

2. Screw the rear adjuster foot to fine tune

the horizontal angle.

To retract the foot, hold up the projector while

pressing the quick-release button, then slowly lower the projector. Screw the rear

adjuster foot in a reverse direction.

If the projector is not placed on a flat surface or the screen and the projector are not

perpendicular to each other, the projected image becomes trapezoidal. To correct

this situation, see "Correcting keystone" on page 26 for details.

• Do not look into the lens while the lamp is on. The strong light from the lamp

may cause damage to your eyes.

• Be careful when you press the adjuster button as it is close to the exhaust vent

where hot air comes from.
