Important: 
1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency fluo-
rescent lights can disrupt remote control operation. 
 
2. Be sure nothing obstructs the path between the remote control and the projector. If the path be-
tween remote and projector is obstructed, you can bounce the remote signal off certain reflective 
surfaces such as projector screens.

Remote Control Operating Range 
The remote control uses infrared transmission to control the projector. It is not necessary to point the 
remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or 
the rear of the projector, the remote functions within a radius of about (7) meters (23 feet) and 30 de-
grees above or below the projector level. If the projector does not respond to the remote control, 
move a little closer.   
Projector and Remote Control Buttons 
The projector can be operated using the remote control or the buttons on the top of the projector. All 
operations can be carried out with the remote control; however the buttons on the projector are lim-
ited in use. The following illustration shows the corresponding buttons on the remote control and on 
the projector. 
 
Some buttons on the projector have two functions. For example, item 7/8 on the projector functions 
both as the volume down button and as the left cursor key in OSD menus.

buttons [B].  
The height-adjusters drop down [C].  
2.  To lower the level of the projector, press the height-adjuster buttons and push down
