Orbiting

A 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.

Adjustment procedure :

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

Press ADJUST to enter the adjustment mode and select Random. The Random Access Adjustment Mode menu will be displayed. Highlight ORBITING by pushing the joy stick forward or backward and press ENTER.
