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 disc up
or down and press ENTER to display the
CRT drive mode menu.
To change the boost mode, push the
control disc 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.
A warning, permanent BOOST mode in
use, will be displayed to inform the user.
When text is on, this warning will be
repeated every time a new source is
selected.
