Below are a few essential items that may make the difference
between a
successful and unsuccessful presentation using slide projection. These
are especially important if you will be presenting in a room without
access to audio-visual support services.
- 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 do
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.
- Spare Bulb - A spare bulb is always good
insurance. 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.
- Coin - Slides sometimes warp or get stuck in
the
projector. The only way to resolve this is to take the tray off using a
screw driver or a coin in the slot in the middle of the tray. Be
sure however, that the plastic lock ring is on your tray before you
remove the tray to prevent dumping slides on the floor.
- Spare Slide Tray - Sometimes a tray will
become
damaged on the projector. The solution is to move the slides to an
undamaged tray.
- Numbered Slides - Numbering your slides in
the
upper right hand corner will provide assurance that you can put the
slides back in the tray in order if they spill out or get stuck.
