Preparation

Preparation for projection
1. Attach the provided power cord to the projector.
2. Plug the power cord in the wall outlet.
3. Remove the lens cap.
Warning:
• Do not look into the lens directly when the projector
is on.
• The lens cap is for protecting the lens. If you leave
the lens cap on the lens with the projector turned
on, it may be deformed because of heat build-
up. Remove the lens cap when you turn on the
projector.
• One of power cords for the U.S., Europe, U.K. and
Korea is provided appropriately.
• This projector uses the power plug of three-pin
grounding type. Do not remove the grounding pin
from the power plug. If the power plug doesn't fi t
your wall outlet, ask an electrician to change the
wall outlet.
• In case that the power cord for the U.S. is provided
with this projector, never connect this cord to any
outlet or power supply using other voltages or
frequencies than rated. If you want to use a power
supply using other voltage than rated, prepare an
appropriate power cord separately.
• Use 100-240 V AC 50/60 Hz to prevent fi re or
electric shock.
• Do not place any objects on the power cord or
do not place the projector near heat sources to
prevent damage to the power cord. If the power
cord should be damaged, contact your dealer for
replacement because it may cause fi re or electric
shock.
• Do not modify or alter the power cord. If the power
cord is modifi ed or altered, it may cause fi re or
electric shock.
Caution:
• Plug in the power cord fi rmly. When unplugging,
hold and pull the power plug, not the power cord.
• Do not plug in or out the power cord with your
hand wet. It may cause electric shock.
Adjustment of the projection angle
For the best projection, project images on a fl at screen
installed at 90 degrees to the fl oor. If necessary, tilt the
projector using the two adjustment feet on the bottom
of the projector.
Using the adjustment feet (front)
1. Tilt up the projector to the appropriate angle.
2. Rotate the adjustment feet (front) for fi ne
adjustment.
Important:
• Install the screen on a fl at wall at 90 degrees to the
fl oor.
• Slanting the projector more than ±10° (right and
left) or ±15° (front and rear) may cause trouble or
explosion of the lamp. You can tilt the projector up
to 8 degrees using the adjustment feet only.
• Images may not be projected in a shape of a
regular rectangle or with its aspect ratio 4:3,
depending on the installation conditions of the
projector and the screen.
• When Auto Keystone in the Installation menu is set
to On, this projector automatically corrects vertical
keystone distortion. For fi ne adjustment, press the
KEYSTONE button on the projector or the remote
control to display KEYSTONE, and adjust the
image by pressing the ,  button (or VOLUME
,  button on the remote control).
In the following cases:
Press the  button.
• The automatic keystone adjustment may not
be carried out correctly because of the ambient
temperature and the installation conditions of the
projector and the screen. In such cases, correct the
keystone manually.
• When the projector is projecting images where
acceleration is present, such as in a vehicle and
aircraft, the automatic keystone adjustment may
not function correctly. In such a case, set Auto
Keystone in the Installation menu to Off and correct
the keystone manually.
• You can correct the vertical keystones. However,
their adjustment ranges are limited in such
correction.
Important:
• When the keystone adjustment is carried out, the
adjustment value is indicated. Note that this value
doesn't mean a projection angle.
• The allowable range of the adjustment value in
the keystone adjustment varies depending on
the installation condition, Input signal and aspect
settings in MENU.
• When the keystone adjustment takes effect, the
resolution decreases. In addition, stripes may
appear or straight lines may bend in images with
complicated patterns. They are not due to product
malfunctions.
• Noise may appear on the screen during the
keystone adjustment because of the type of the
video signal being projected and the setting values
of the keystone adjustment. In such cases, set the
keystone adjustment values in the range where the
image is displayed without noise.
• When the keystone adjustment is carried out, the
image may not be displayed correctly because of
the type of input signal.
