BIf there are any obstacles in between
the remote control unit and the
receivers, the remote control unit may
not operate correctly.

If strong light is allowed to shine onto
the remote control signal receiver,
correct remote control operation may
not be possible. Place the projector as
far away from light sources as possible.
BIf facing the remote control unit
toward the screen to operate the
projector, the operating range of the
remote control unit will be limited by
the amount of light reflection loss
caused by the characteristics of the
screen used. NOTE:

Operating range
If the remote control unit is held so
that it is facing directly in front of the
remote control signal receptors on
the front or rear of the projector, the
operating range is within
approximately 7 m (23´) from the
surfaces of the receptors.
Furthermore, the remote control unit
can be operated from an angle of
±30° to the left or right and ±15°
above or below the receptors. #Open the cover.

Preparation
Setting the projector IDs number for
remote control unit
When controlling multiple projectors individually or simultaneously with\
 a
single remote control unit, projector IDs must be set into the remote co\
ntrol
unit as described in the following steps.
#Press the ID SET button on the remote control unit.
ID number  “ALL ” will be displayed on the screen.
$ Press and hold the ID SET button for more than 2 seconds.
The ID number will change into  “1 ”. The ID SET button will now toggle
through ID numbers  “2 ”,  “3 ”,  “ALL ” and  “1 ” each time it is subsequently
pressed.
% Select the ID number you wish and then press the ENTER button.
When the projector ID coincides with the remote control unit

The ID number will be displayed in white on the screen. 
If the projector ID and ID for the remote control unit are not the same,\
 the
projector ID is displayed in green.

The Power indicator on the projector will flash for 5 seconds.
If the projector ID and ID for the remote control unit are not the same,\
 the
Power indicator will stay illuminated red.
NOTE:
B The projector ID number in the remote control unit is set to  “ALL ” by
default. It is therefore not necessary to set a projector ID number when\
only one projector is used.
B The projector can be turned ON/OFF from the remote control unit only if
the projector ID is set in the remote control unit. For more details on
projector ID setting, see page  48.

Connections
Notes on connections
BRead the instruction manual for each system component carefully before
connecting it.
B Turn off the power supply for all components before making any
connections.
B If the cables necessary for connecting a component to the system are not\
included with the component or available as an option, you may need to
fashion a cable to suit the component concerned.
B If there is a lot of jitter in the video signal which is input from the \
video
source, the picture on the screen may flicker. In such cases, it will be\
necessary to connect a TBC (time base corrector).
B The projector has built-in speakers. However, you will need to connect a\
separate audio system to the AUDIO OUT jack if your needs specify high
sound volumes. No sound will come out of the projector ’s built-in speakers
while the AUDIO OUT jack is being used.
B It may not be possible to connect some types of computer. Refer to the l\
ist
of compatible signals on page  63.

Projection distances
Setting-up dimensions which are not given in the above table can be
calculated using the formulas below.
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
NOTE:
BThe dimensions in the table above and the values obtained from the
above formulas may contain slight errors.
BIf you use the projection distance for the 16:9 screen, the
4:3 projection image overflows the screen at the top and
bottom.
BIf you set up the projector vertically, it may cause to
damage the projector.
B
It is recommended that you set up the projector in
a place that is tilted at less than 
±35°. Setting up
the projector in places that are tilted at more than
±35°may cause malfunctions.
Make sure that enough space is kept for the air 
outlet port.
