AUTOMATIC FAN CONTROL
The fan operation is controlled by the overhead projector light (OHP). This
safety feature ensures that the fan is always operating as long as the OHP
is turned on. When the OHP is turned off, the fan automatically stops to
minimize noise. The power supply must be attached to the panel for the
fan to work properly.

SET-UP MEMORY
The user controlled set-up that usually is done when the panel is adapted
to a new computer, is automatically memorized for future use. The set-up
information is stored in a non-volatile memory.

The memory can store 40 different sources/modes. Approximately 10
sources are predefined, while the remaining 30 are available for customer
set-up of sources.

The custom sources will be stored in new locations if their sync pattern is
different from those predefined. If the set-up is only a variety of a standard
source (same sync pattern) the old setting will be changed and stored in
the existing location.

Most settings are stored individually for each source, including contrast,
brightness, tune etc. See the remote control table above.

CONTRAST
The contrast of an image is defined as the relation between dark and light
colors. An image of high contrast is often regarded as 'hard', as compared
to the 'soft' feeling of a low contrast image. Low contrast is recommended
for long term viewing, while high contrast is used to enhance details. Use
the CONTR keys on the remote control (RC) to adjust the contrast. Also
see Brightness. The contrast setting is stored individually for each source.

BRIGHTNESS
The brightness is the amount of white in an image. The brightness is
adjusted to the ambient lighting conditions. Usually, a bright, low contrast
image is preferred. Use the BRIGHT keys to adjust brightness. See also
