Range of Remote Control Operations
Depending on the distance and angle from the main unit’s light receiving area, there are cases 
where the remote control will not function. Ensure that the remote control is used within the fol-
lowing conditions:

 Operable distance: Approximately 10 meters

 Operable range:
Point
·Ensure that the [R/C ON OFF] switch is set at [ON] when using the remote control unit.
·Aim the remote control at the projector’s light-receiving area.
·There are cases where the operable distance (approximately 10 meters) of the remote 
control is diminished when signals are reflected off screens depending on the type of 
screen in use.
·Ensure that sunlight and florescent lighting is not shone directly into the projector’s light-
receiving area.
·If the remote control will not function or malfunctions, there is a possibility that the batter-
ies need changing. In this event, replace the batteries accordingly.
·Use the optional remote control receiver if it is to be used at a distance of 10m or more.

Point
·Specified batteries: Two three-cell alkaline manganese batteries (LR6).
·The batteries should be replaced approximately once every three months when used for 
thirty minutes per day.
Caution
Ensure that unused batteries of the same type are used. 
						

							22 - Installation Procedure
Installation Procedure
Determines the projection angle and projection distance to ensure the most suitable screen 
display.
Installation example
The projector may be installed in locations that conform to the installation conditions and pro-
jection methods.
Viewing projected images from the front
Viewing projected images from the front with a ceiling suspended projector
Use the optional ceiling suspension unit and set the ceiling suspension parameter to [ON]. (see page 69)
Viewing images projected onto half-transparent screens from the rear
·Set the rear parameter to [ON]. (see page 69)
·Ceiling suspension is also possible with the use of the optional ceiling suspension unit.
Caution
·Do not block the ventilation outlet at the back of the projector or the Air Filter (suction 
inlet) on the rear panel.
·There are cases where material or paper get sucked onto the Air Filter on the rear panel 
when the projector is in use, so attention must be paid to prevent this.
·Do not place the projector in a location where it is subject to the direct air flow from air con-
ditioners or heaters.
·When the projector is to be placed near a wall, ensure that there is at least 20cm of space 
between the wall and the projector.
·Do not cover the projector with table cloths or other material. 
						

							 Installation Procedure - 23
Screen size and projection distance
Determines the distance that the screen must be from the lens in order to obtain the required 
screen size.
The projector’s Standard Lens is approximately a 1.4x zoom lens and the largest screen size is 
about 1.4 times the size of the smallest screen.
Using the following table for reference purposes, install the projector so that the screen size is 
smaller than the screen.
Point
·The projection distances listed above are the distances when the standard lense is in use. 
If optional lenses are to be used, refer to the relevant instruction manuals for further 
details.
·The screen size will become smaller when the trapezoid correction function is used.

							24 - Installation Procedure
Projection angles
The optimum projection screen is acquired by placing the center of the projector’s lens and a 
right-angle to the screen.
When viewing from the side* It is possible to move the projection position up and down with the lens shift function
When viewing from the top or bottom
Point
Although the projection position can be adjusted with the foot lever  (see page 45), there 
are cases where the screen will distort into a trapezoid shape. In this event, adjust the trap-
ezoid distortion with the trapezoid correction function. (see page 46

							 Connecting the projector to a computer - 25
Connecting the projector to a computer
Switch off the power supply to the projector and computer before attempting to make the 
connection.
Eligible computers
There are computers with which connections cannot be established and computer that cannot 
be used for projection purposes even though a connection has been established. First of all, it is 
necessary to confirm that a connection can be established with the computer in use.

 Conditions for eligible computers
Condition #1: The computer must be fitted with an image signal output port
Check to ascertain that the computer is fitted with ports that will output image signals, 
such as the [RGB Port], the [Monitor Port] and the [Video Port]. If you have trouble 
confirming this, refer to chapter on external monitor connections in the computer’s 
instruction manual.
There are computers, such as combined computer/monitor models and laptop models, 
that do not allow connections or for which optional external output ports must be 
purchased.
Point
Depending on the computer, there are cases when it is necessary to switch the image sig-
nal output with the connection key ( , etc.,) and the settings.
The table shown above provides examples for certain products. Refer to the computer’s 
instruction manual for further details.
Condition #2: The resolution and frequency of the computer must be within the 
boundaries listed in the chart on the next page.
Projection will not be possible if the computer does not support the output image signal 
resolutions and frequencies shown in the chart on the next page (there are cases where 
projection is possible, but vivid projection will not be possible).
Confirm the image signal resolution and frequency with the computer’s instruction 
manual.
There are also computers available that allow the output resolution to be amended. In this 
case, amend the parameters to fit within the ranges shown in the chart on the next page.
