About the remote control signal
The remote control works with 
the projector’s remote sensor. 
This projector has two remote 
sensors on the front and back 
sides.
The sensors can sense signals 
within the following range:
60 degrees (30 degrees to the 
left and right of the sensor) 
within about 3 meters.
• You can deactivate one of the sensors using the REMOTE RECEIV. 
item in the SERVICE menu of the OPTION menu (
95).
• The remote control signal refl ected in the screen may be available. If it is 
diffi cult to send the signal to the sensor directly, try to make the signal refl ect.
• The remote control uses infrared light to send signals to the projector (Class 
1 LED). 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 
fl uorescent lamp) shines on the remote sensor of the projector. Adjust the 
position of projector avoiding those lights. NOTE
