7. Service Mode
When available?
CRT Run In Cycle can only be activated when one or more memory blocks on an internal # pattern are available.
If no such a block is available, the projector cannot run CRT Run In Cycle 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 CRT Run In Cycle .
What is done?
A flashing white image (5sec. on, 5 sec. off) is generated for 5 min. on the first internal block. In the next 5 min., the next internal
block available 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.

CRT Drive Mode
What can be done?
The projector CRT’s can be driven with the normal current (normal mode), a lower current (economic mode) or with a higher current
(boost mode). The higher the current, the higher the light output but the lifetime of the CRT’s will shorten.
Which CRT Drive Modes are available?
Normal
Default Setting
Economic
Lower drive current to the CRT’s, the lifetime of the CRT’s will
enlarge but the light output will reduce.
Temporary Boost
Higher drive current to the CRT’s, the lifetime of the CRT’s
will shorten but the light output will be higher. This situation
is temporary, when restarting the projector, the drive mode is
automatically set to normal.
Permanent Boost
Higher drive current to the CRT’s, the lifetime of the CRT’s will
shorten but the light output will be higher. This setting will be
saved in the EEPROM. When restarting the projector, it will
start up in boost mode.
