CRT run in cycle
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 (5sec on, 5 sec off) is
generated and that 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.
Highlight 'CRT run in cycle' with the control disk and press ENTER
to start .
If a memory block adjusted on an internal # pattern is available, the
CRT run in cycle will start when pressing ENTER. 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.
