Projecting
This section provides explanations on starting and ending projection, and on the basic func-tions for adjusting projected images.




 
Projection
Images can be projected after all connections have been completed.
Preparations
1Connect the projector to a computer and video equipment. (see page 26, 36)
2Remove the Lens Cover.
3Attach the supplied Power Cord to the projector.
Check to confirm the shape of the projector’s Power Inlet and Power Connector, align the 
connector in the correct direction, and then insert it as far as it will go.
Wa r n i n g
·Never look directly into the lens once the power supply has been switched on. Failure to 
observe this may result in the powerful light damaging eyesight.
·Ensure that the Power Cord supplied is used. The use of cables other than the one supplied 
may result in the outbreak of fire or electric shocks.
Caution
Do not perform any projection tasks with the Lens Cover attached. Failure to observe this may 
result in the cover becoming malformed due to heat.

Keystone adjustment
Make the necessary adjustment when the screen has been distorted into a trapezoid with foot 
adjustment.
1Press the [Keystone +, -] button to lengthen the screen sidewards.
It is possible to use the trapezoid correction function (through 64 stages) as long as the tilt 
angle of the projector is within a maximum vertical range of between 30 degrees to 20 
degrees.
The maximum value for the tilt angle differs as shown below in accordance with the size 
of the projected image adjusted with zoom.
Point
·The screen will be reduced in size when keystone correction has been performed.
·The status of the keystone correction will be recorded. Perform readjustments that match 
the installation position when the projector position or angle have been changed.
·Reduce the sharpness if blurring occurs after keystone correction. (see page 66
)
·Keystone correction is performed from the menu (see page 68)
