How to Put an Overhead Projector Together

An overhead projector is an audio-video device that transmits a translucent image onto a screen using a series of lenses. Setting up the overhead projector correctly ensures that the image is both right side up as well as in focus. The procedure to put the projector together is straightforward and requires a tool that most homes or offices have on hand.

  Place the overhead projector's base on a table or stand that faces the wall or screen that it will be used with. Rotate the projector so that the back is facing you. Loosen the screws around the bracket at the top back of the base, using the Allen wrench.
