About the remote control signal
T h e   r e m o t e   c o n t r o l   w o r k s   w i t h   t h e   p r o j e c t o r ’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.
