•The battery is not 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 and confirm that the wall outlet works.
•The battery is installed in the wrong orientation. See “Install Battery” on page 12.
•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. See “Charge the Battery” on page 14.
The image is not visible or is very dim.
•The 3M MPro120 is a battery operated projector 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 a white image with the red 3M logo.
The projector is displaying a question mark.
