Overhead Projection Survival KitAll it takes is
a few essentials to make the difference between a
successful and unsuccessful presentation using
overhead projection. Some perceive overhead
projection as being less professional than
slides in a formal setting. To prevent that
impression, a smart presenter using overhead
projectionwill need to prepare a survival kit
with the following items.

Extension Cord

• Rooms sometime have the power outlets located in
  the most inconvenient places. An extension cord
  may resolve some difficulties.

10
Ungrounded Plug Adapter

• Some building still do not have three-pronged
  grounded outlets. A two-pronged adapter will
  allow you to use these older power outlets
  without damaging the overhead projector plug.

11
Spare Bulb

• Some overhead projectors have a spare lamp
  changer inside the projector. But 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 class surface of bulbs with
  your fingers, but handle them by their metal or
  porcelain bases or use a handkerchief.

12
Transparency Pen

• You may want to write on a transparency to
  illustrate, clarify or highlight a point. If you
  plan to use the transparency again, be sure to
  use a water-soluble transparency pen.
• You may even want to cover transparencies with
  clear sleeves to avoid damaging your original.

Acetate Film

• Extra blank acetate film provides additional
  chalkboard space for responding to audience
  questions and comments.
