Service Mode

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.

Projector warm up

Highlight 'Projector warm up' by pushing the control disk up or down and press ENTER to select the projector warm up menu.

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.
