Troubleshooting

The projector will not turn on.

•The battery is not properly installed, or the power adapter is not connected to the projector and a working wall outlet. Test the electrical outlet by plugging another electrical device (like a radio) into the wall outlet to confirm that the wall outlet works.

•The battery is installed in the wrong orientation. See “Install Battery” on page 11.

•Attempt to remove and replace the battery.

•Hold down the power button until the projector powers up.

The status indicator is flashing red when the power button is held down.

•The battery needs to be charged or reinstalled. See “Charge the Battery” on page 13.

The image is not visible or is very dim.

•The 3M MPro150 projector is a battery-operated device and requires controlled lighting conditions. The image may appear very dim in brightly lit rooms.

•Make sure the status indicator is green. This indicates that the projector is powered on and projecting an image.

•Project the image onto a flat, white surface.

•Decrease the light on the surface where the image is being projected.

•Decrease the size of the image.

•When there is nothing connected to the projector, it will project the home screen.

The projector is displaying a question mark.

•The projector does not support the video or computer input signal. Switch to a signal that the projector supports. See “Supported Computer Signals” on page 51.

A computer is connected to the projector but the projector will not display the computer’s image.

•Unplug the VGA-audio cable from the projector and the home screen will display.

•Plug the VGA-audio cable into the projector and the icon in the upper-left corner of the image will display the “VGA-Audio cable” icon. See “Video Mode Icons” on page 21.
