may result in malfunction and/or damage to the device and/or projector . 
NOTE  • Whenever attempting to connect a laptop computer to the projector, be sure 
to activate the laptop’s RGB external image output (set the laptop to CRT display or to 
simultaneous LCD and CRT display). For details on how this is done, please refer

Remote control
Using the remote control
CAUTION  ►Be careful in handling the remote control.
• Do not drop or otherwise expose the remote control to physical impact.
• Do not get the remote control wet or place it on wet objects. Doing so may 
result in malfunction.
• Remove the batteries from the remote control and store them in a safe place if 
you won’t be using the remote control for an extended period. 
• Replace the batteries whenever the remote control starts to malfunction. 
• When strong lights, such as direct sunlight or light from an extremely close 
range (such as from an inverter fluorescent lamp), hit the projector’s remote 
sensor, the remote control may cause to function. Adjust the direction of the 
projector to keep light from directly hitting the projector’s remote sensor.
The remote control works with the projector’s remote sensor.
• The range of the remote sensor is 3 meters with a 60- degree range (30 degrees 
to the left and right of the remote sensor).
• Also a remote signal reflected in the screen etc. may be available. If it is difficult 
to send a remote signal to the sensor directly, please try.
•  Since  the  remote  control  uses  infrared  light  to  send  signals  to  the  projector 
(Class1  LED),  be  sure  to  use  the  remote  control  in  an  area  free  from  obstacles 
that could block the remote control’s output signal to the projector.
