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
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.
