CRT run in cycle
What can be done ?
Only necessary when a new picture tube is installed.
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.
How to select CRT run in cycle ?
1. Push the cursor key
é
or
ê
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.

Projector warm up
What can be done ?
When in the ON position (and the CRT run in cycle is OFF), the projector can start up with a warm up periode of 20 minutes. During
the start up a warm up menu will be displayed. This menu offers the possibility to skip the warm up periode anyway by pressing
the EXIT key and offers the possibility to adjust the horizontal and vertical amplitude of this white image with the control disc. During
this warm up period, a full white image is shifted on the CRT faceplate to avoid a burn in.
Every 30 seconds a text box will be displayed on another place on the screen with the remaining time to go.
When EXIT is pressed during this warm up periode, the warm up menu will be redisplayed with the remaining time indication. Press
another time EXIT to interrupt the warm up cycle.
When the warm up option is OFF, when switching on the projector, it starts immediately with the projection of the selected source.
