Projector - Remote Control Troubleshooting 
 
If a projector cannot be controlled with the remote control, please check the following: 
 
1.  Check the batteries in the remote control to ensure that they are good and that they are 
installed properly. 
 
2.  Confirm that the Main Power Supply switch on the Projector is turned ON. 
 
3.  Confirm that you are using the correct remote control with the projector that you 
attempting to control. You may need to refer to the User’s Manual to confirm the correct 
remote control model number. It is very important that you are utilizing the correct 
remote control because some model remote controls are not compatible with some 
projectors. 
 
For example, the proper remote control for Projector Models NP3250/NP2250/NP1250/ 
NP3250W/ NP3150/NP2150/NP1150/NP3151W would be model number 7N900801 as 
shown below in Figure 1.

4.  Check the IR transmitter via digital image (cell phone, digital camera, etc.) 
 
a.  Point the remote control IR transmitter towards a digital camera or cell phone 
camera (as shown in Figure 2). 
b.  Press the Power button on the remote control and you should see the light from 
the IR transmitter flashing as you depress the button (see arrow in figure). 
c.  If the light is observed, the IR transmitter is working properly. Continue 
troubleshooting with the next step. 
d.  If the light is NOT observed, the IR transmitter is NOT working properly. You 
must resolve the problem with the batteries or obtain a new remote control.
