CAUTION:
TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION CORD,
RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE
EXPOSURE.
NOTE:
SINCE THIS PROJECTOR IS PLUGGABLE EQUIPMENT, THE SOCKET-OUTLET SHALL BE INSTALLED NEAR THE
EQUIPMENT AND SHALL BE EASILY ACCESSIBLE.
WARNING
Use the attached specifi ed power supply cord. If
you use another power-supply cord, it may cause
interference with radio and television reception.
Use the attached RS-232C cable and RGB cable with
this equipment so as to keep interference within the
limit of a FCC Class B device.
This apparatus must be grounded.
DO NOT LOOK DIRECTLY INTO THE LENS WHEN

COMPLIANCE NOTICE
This Projector complies with the requirements of the
EC Directive 89/336/EEC “EMC Directive” as amended
by Directive 92/31/EEC and 93/68/EEC, and 73/23/
EEC “Low Voltage Directive” as amended by Directive
93/68/EEC.
The electro-magnetic susceptibility has been chosen
at a level that gains proper operation in residential
areas, on business and light industrial premises and
on small-scale enterprises, inside as well as outside of
the buildings. All places of operation are characterised
by their connection to the public low voltage power
supply system.
WARNING
Use the attached RS-232C cable and RGB cable with
this equipment so as to keep interference within the
limits of an EN55022 Class B device.

CAUTION:
• Use of a battery of wrong type may cause explosion.
• Only Carbon-Zinc or Alkaline-Manganese Dioxide type batteries should be used.
• Dispose of used batteries according to your local regulations.
• Batteries may explode if misused. Do not recharge, disassemble, or dispose of them in fi re.
• Be sure to handle the batteries according to the instructions.
• Load the batteries with its positive (+) and negative (-) sides correctly oriented as indicated on the remote control.
• Keep batteries out of reach of children and pets.
• Remove the batteries, if the remote control is not used for a long time.
• Do not combine a new battery with an old one.
• If the solution of batteries comes in contact with your skin or clothes, rinse with water. If the solution comes in
contact with your eyes, rinse them with water and then consult your doctor.
2. Check the polarity (+), (-) of the batteries, and set them
correctly, inserting their (-) side fi rst.
• If the battery is inserted from the (+) side fi rst, inserting
the (-) side is diffi cult because the coil spring end hits on
the battery side. If the battery is forced to insert in this
way, the outer label of the battery may get ripped and it
may cause a short-circuit and heating.
3. Attach the rear lid.
Important:
• Use two size-AAA batteries (R03).
• Replace the two batteries with new ones when the remote
control is slow to operate.

Setting up your projector
Setting up the screen
Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the
projection angle of the projector. (See below.)
• Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of
the screen center.
• Do not install the screen where it is exposed to direct sunlight or lighting. Light directly refl ecting on the screen
makes the projected images whitish and hard to view.
Basic setup
Determine the distance from the screen to the projector according to the size of the images to be projected. (See
Page 11.)
• Do not place this projector on a carpet or blanket because the exhaust vent and the intake vent on the bottom
surface are blocked and the inside of the projector is heated, causing a breakdown or fi re.
• Depending on the installation conditions, warm air that is emitted from the exhaust vents may fl ow into the intake
vent, causing the projector to display “TEMPERATURE!!” and then stop projecting images.

Adjusting the projection angle
This projector is provided with three feet for
adjusting the projection angle on the bottom
surface. Adjust the projection angle depending on
the position of the projector.
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.
Screen
Adjustment feet
(rear)
1. Tilt up the projector to the appropriate angle.
2. Press the foot adjustment buttons next to the
adjustment feet (rear), and the adjustment feet
will come out.
3. Release the buttons to lock the adjustment feet
(rear) to that position.
4. Rotate the adjustment feet (rear) for fi ne
adjustment.
After using the projector:
5. Put the adjustment feet (rear) back into the
projector by pressing the foot adjustment
buttons.
• If necessary, rotate the adjustment feet (front) for
fi ne adjustment.
When projected images are distorted to a
trapezoid:
When the screen and the projector are not placed
perpendicularly to each other, projected images
become trapezoidal. If you cannot make the
projector and the screen perpendicular to each
other by mechanical adjustments, adjust keystone.
(See Page 16.)
• When the keystone adjustment is applied, the
correct aspect ratio may not be obtained.
• When the keystone adjustment is applied, the
resolution lowers. In addition, vertical stripes appear and straight lines bend in images with complicated patterns. To prevent such symptoms,
keep the screen and the projector perpendicular
to each other as much as possible.
• Though the projected image may be distorted
momentarily when you change the setting value
of the keystone adjustment, such symptom is not
a malfunction.
• Though the projected image may be distorted
depending on the setting value of the keystone
adjustment and the type of the input signal, such
symptom is not a malfunction. In such a case,
adjust the setting value within the range where
the projected image is not distorted.
• The setting value displayed at the time of the
keystone adjustment may vary depending on the
type of the input signal.
• The keystone mode does not function when the
REAL mode is applied.
