About the remote control signal
The remote control works with the projector’s remote sensors. This projector has three
remote sensors on the front, on the top, and on the back.
The sensors can be respectively turned active or inactive using the “REMOTE RECEIV”
in the SERVICE item of OPTION menu (46). Each sensor senses the signal within the
following range when the sensor is active.
The front and top sensors:
60 degrees (30 degrees to the left and right of the
sensor) within 3 meters about.
The back sensor:
40 degrees (0 degrees to the left and right of the
sensor) within 3 meters about.
Remote control
NOTE • The remote control signal reflected
in the screen or the like may be available. If it is
difficult to send the signal to the sensor directly,
attempt to make the signal reflect.
• The remote control uses infrared light to send
signals to the projector (Class  LED), so be sure
to use the remote control in an area free from
obstacles that could block the remote control’s
signal to the projector.
• The remote control may not work correctly if
strong light (such as direct sun light) or light from
an extremely close range (such as from an inverter
fluorescent lamp) shines on the remote sensor
of the projector. Adjust the position of projector
avoiding those lights.
