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.
