About the remote control signal

The remote control works with the projector's remote
sensor. This projector has a remote sensor on the front.
The sensor senses the signal within the following range
when the sensor is active:
60 degrees (30 degrees to the left and right of the sensor)
within 3 meters about.
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 1
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.

Changing the frequency of remote control signal

The accessory remote control has the two choices on signal
frequency Mode 1:NORMAL and Mode 2:HIGH. If the remote
control does not function properly, attempt to change the
