ORBITING
Orbiting (option)
Static pictures are very often shown on large screen projectors,
espectially in process control and presentation applications. Due to
the fact that the same picture information is shown for a long period
on the same place, picture tubes can be damaged by 'local burn-in'.
To avoid this problem, BARCO has designed special Orbiting circuitry
which moves the picture very slow around a predefined screen area.
The orbiting circuitry has been designed using a very long cycle time
to make the movement of the projected image imperceptible.

The orbiting path is automatically added to the Random access
adjustment mode menu when installed.
