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.

Important Note: To enter the On-Screen Menu (OSM) without a properly working
remote control, you must utilize the Menu button on the projector and scroll through
the tabs and selections with the Up/Down/Right/Left arrow buttons, and Enter/ Exit
buttons. Not all of the models have the same Menu structure, therefore, some of the
Tabs and Settings described in the following sections may be slightly different between
models.

5. Using the Menu button on the projector, confirm that the Control ID setting is set to

“Off.” The Control ID setting can be found in the projector’s OSM under Setup 
Installation(2)  Control ID.

See Figures 3 and 4.
