Precautions while using Overhead Projectors
Spend time going over the equipment manual in detail and practicing in advance. Learn where the On/Off switch is located and where the lamp is if you need to replace it mid presentation keep a spare bulb on hand for this purpose. Before the presentation begins, tape the electrical cord to the floor for safety reasons and clean the projector glass. Adjust the projector so the image is easily readable and sitting high on the screen to provide all audience members a good view of the information on the screen. Stand at the projector and face the audience during the presentation. Talk to the audience, not to the screen. Stand on one side to minimize distractions caused by your movements.
