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.
ENTER starts the 'CRT run in' when an internal generated # pattern
is available.
EXIT returns to the Path Selection main menu.

memory blocks adjusted
on an internal # pattern;
if no such block is
available, the projector
can't run the procedure
and leaves the adjustment
mode.

The ON/OFF option can be toggled with the ENTER key.
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 disk. 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.
CRT Drive Mode
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).
To change the drive mode, highlight 'CRT drive mode' by pushing the
control stick forward or backward and press ENTER to display the
CRT drive mode menu.
To change the boost mode, push the control disk up or down to select
a display mode and press ENTER to select.
The following modes are available :
- Normal
- Economic : Lower drive current to the CRT's, the lifetime of the
CRT's will enlarge but the light output will reduce.
- Tempory 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 tempory, when restarting the projector, the drive mode is auto-
matically 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.
Select with or
then <ENTER>
<EXIT> to return.
