CRT Run In Cycle

What can be done?

Only necessary when a new picture tube is installed or when CRT arcing continues. The CRT run in cycle option can only be activated when memory blocks on an internal # pattern are available. When one or more such blocks are available, a flashing white image (5 sec on, 5 sec off) is generated and then for 5 min on the first internal block. In the next 5 min, a second internal block will be used to generate the flashing white image. The image will also be shifted in a vertical way to prevent a CRT burn in. To quit the CRT run in cycle option, press EXIT.

How to select CRT run in cycle?

1.Push the cursor key or to highlight 'CRT run in Cycle' (menu 1).

2.Press ENTER to start up. If a memory block adjusted on an internal # pattern is available, the CRT run in cycle will start. If no such a block is available, the projector cannot run the CRT run in option and leaves the adjustment mode. If you still want to run CRT run in cycle, create first a memory block on an internal # pattern and restart the CRT run in option.
