Below are a few essential items that may make the difference between a successful and unsuccessful presentation using computer projection. These are especially important if you will be presenting in a room without access to audio-visual support services.
- Floppy Disk with Critical Files- In case you have a file that becomes damaged or unreadable, you will need backup files on floppy that can be reloaded.
- Spare Bulb - A spare bulb is always good insurance.
- Interface Cables - You may want spares in case of emergencies.
- Remote Control - This gives you leader so you can present away from the computer projector and still use the controls.
- Extension Cord - Rooms sometimes have the power outlets located in the most inconvenient locations. An extension cord may resolve such difficulties.
- Ungrounded Plug Adapter - Some rooms may not have three-prong grounded outlets. A two-prong adapter will allow you to use these older power outlets without damaging the overhead projector plug. Make sure you know how to change the bulb in case it burns out during your presentation. Do not touch the glass surface of bulbs with your fingers, but handle bulbs by their metal or porcelain bases.
