Preparation for the remote control unit
NOTE:
BDo not drop the remote control unit.
BKeep the remote control unit away from liquids.
BRemove the batteries if not using the remote control unit for long periods.
BDo not use rechargeable batteries.
BIf 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.
BIf there are any obstacles in between the remote control unit and the
receptors, the remote control unit may not operate correctly.
BIf strong light is allowed to shine onto the remote control signal receptor,
correct projector operation may not be possible. Place the projector as
far away from light sources as possible.
B
If 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.

BIf ID number is set to “ALL” by pressing the ID ALL button, the
projectors can be controlled regardless of their ID number setting.
BThe projector cannot be turned on and off from the remote control unit if
the “CONTROLLER ID” does not match the projector ID number. For
more details on projector ID number setting, see page 49.
BThe 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.
