Tip 200: Master the technology
You must master whichever technology you will use for your presentation:
Back projection
Microphone
Video
Slide projector
Laser pointer
Lighting circuit
If you cannot operate any of these items of equipment, it gives your audience the impression that you have not had the respect or decency to prepare properly for the talk. Nothing irritates an audience more than watching somebody fiddle with a computer after the start of a presentation.
