Is there a recommended sequence of turning on my product and peripherals?

• It's best to turn on the projector and its attached equipment in the following order: 1. Video source (such as a VCR), if your video source is not your computer 2. Audio source (if different from computer or video source) 3. External amplified speaker or PA system (if necessary) 4. Projector 5. Computer When you are ready to turn off the equipment, turn them off in the reverse order.
