Operation

Switching input signal
The projector can be connected to multiple devices 
at the same time. However, it can only display one 
full screen at a time. To cycle through the available 
input sources, press SOURCE on the projector or 
remote control. The selected source name will 
display in the lower right corner of the screen for 3 
seconds after each button press.
The projector features PIP function which allows 2 
different signals to be displayed at the same time. 
See 
for details.
The brightness level of the projected image will 
change accordingly when you switch between 
different input signals. Data (graphic) "PC" presentations using mostly static images are 
generally brighter than "Video" using mostly moving images (movies). When switching 
between different signal inputs, you will need to adjust the ambient lighting conditions for 
the best picture quality.
The input type affects the options available for the Preset Mode. See
 for details.
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 2 quick-release adjuster feet and 2 rear adjuster feet. These 
adjusters change the image height and projection angle. To adjust the projector:
1.
Press the quick-release buttons and lift the 
front of the projector. Once the image is 
positioned where you want it, release the 
quick-release buttons to lock the front 
adjuster feet in position.
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 buttons as 
they are close to the exhaust vent where hot air comes from.
2.
Screw the rear adjuster feet to fine tune the 
horizontal angle.
To retract the foot, hold up the projector while 
pressing the quick-release buttons, then slowly 
lower the projector. Screw the rear adjuster feet in 
a reverse direction.
If the screen and the projector are not 
perpendicular to each other, the projected image 
becomes vertically trapezoidal. To correct this 
situation, adjust the value of Keystone in the 
Display menu, on the projector control panel, or on the remote control. Se
 for details.
