You can display computer images on both the projector and a separate monitor using two sets of RGB cables.

Note

• RGB signals and Component signals can be output to the monitor.
• For this connection, another RGB cable (commercially available) is required.

Audio signals input from equipment connected to each audio input terminal of the projector can be output to audio equipment.

Note

• ø3.5 mm minijack to RCA audio cable (commercially available) is required for audio input.
• Turn off the power of both the projector and audio equipment when connecting.
• When turning off the power in the case of connecting an amplifier or other audio equipment, first turn off

the power of the amplifier and then turn off the power of the projector.

• By using external audio components, the volume can be amplified for better sound.

▼On-screen Display

• Do not unplug the power cord during projection or cool-

ing fan operation. The cooling fan in this projector contin-
ues to run for about 90 seconds after the projector enters
the standby mode. This can cause damage due to rise in
internal temperature, as the cooling fan also stops.

• The power indicator illuminates green.
• After the lamp indicator illuminates, the projec-

tor is ready to start operation.

• When System Lock is set, the keycode input

screen appears. Enter the right keycode to
start projection. See page 

 for details.

Note

• The lamp indicator illuminates or blinks, in-

dicating the status of the lamp.

Green: The lamp is ready.
Blinking green: The lamp is warming up

or shutting down.

• When switching on the projector, a slight flicker-

ing of the image may be experienced within the
first minute after the lamp has been illuminated.
This is normal operation as the lamp's control
circuitry is stabilizing the lamp output charac-
teristics. This does not indicate malfunction.

• If the projector is put into standby mode and

immediately turned on again, the lamp may
take some time to illuminate.

• The front adjustment foot comes out.

• The projector is adjustable up to approxi-

mately 12 degrees (6 steps).

• When lowering the projector, it may be

difficult to move the front adjustment foot
because the installation surface is diffi-
cult to slide. In this case, pull the pro-
jector back slightly and adjust its height.

• When adjusting the height of the pro-

jector, trapezoidal distortion occurs.
When “Auto Keystone” of the “Options2”
menu is set to “

” (ON) (see page 

),

keystone correction functions automati-
cally to correct trapezoidal distortion.
When you want to adjust the automati-
cally corrected image, use the manual
keystone correction.  (See page 

.)

• Do not press the HEIGHT ADJUST button

when the front adjustment foot comes out
without firmly holding the projector.

• Do not hold the lens when lifting or lower-

ing the projector.

• When lowering the projector, be careful not

to get your fingers caught in the area be-
tween the adjustment foot and the projector.
