Possible Mistake
The batteries could be improperly

Maybe the batteries are empty.
Maybe the objective lens is not
perfectly parallel to the projection
surface (wall or ceiling).
The distance to the projection sur-
face (wall or ceiling) is perhaps too
small.
The focus may not be adjusted
properly.

Check to see whether the batteries are placed in exactly the way described
in the instructions. Pay special attention to the directions of the terminals

Install new, unused batteries as directed in the instructions. Pay special
attention to the directions of the terminals (+/-).
