General Guidelines - Black Box AC400A Owner's Manual

2.3 General Guidelines

Follow these guidelines when you
use the Projection Panel.
• Be sure the Projection Panel
is on whenever the overhead
projector is turned on.
CAUTION
If the Projection Panel is not
on when it is on top of an
operating overhead pro-
jector, the Panel could
sustain damage.
• Do not use the Projection Panel
for extended periods of time on
an overhead projector known for
discoloring or melting standard
transparencies.
• When you use the Panel with a
high-wattage projector or if you
notice extreme discoloration of
the Panel, periodically remove
the Panel from the overhead
projector to allow it to cool.
• The bottom of the Panel can
become very hot to the touch
after use. Be careful to let the
Panel cool before lifting it.
• Do not block the Projection
Panel fan or free air movement
under and around the Panel.
Air flows from back to front.
• Turn the overhead projector off
and unplug the Projection Panel
when not in use.
CHAPTER 2: Introduction
• Handle the Projection Panel as
you would anything made of
glass. Be especially careful not
to drop it.
• You can easily clean the
Projection Panel with standard
non-abrasive glass cleaner. Apply
the cleaner to the cleaning cloth
and then wipe the glass surface
lightly. Do not use excessive
amounts of liquid or pressure on
the top or bottom optical panels.
• Avoid scratching the Projection
Panel surface with sharp metal
objects. The top surface is made
of glass or a scratch-resistant
hardened polymer. If you need
to clean the surface, use normal
glass-cleaner solution. Do not
use abrasive cleaners, solvents,
or other harsh chemicals.
• Avoid leaving the Projection
Panel in direct sunlight or
extreme cold for extended
periods of time.
