Service Mode
Projector warm up
Highlight ‘Projector warm up’ by pushing the control disc 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 pro- jector can start up with a warm up period of 20 minutes. During the start up a warm up menu will be displayed. This menu offers the pos- sibility to skip the warm up period anyway by pressing the EXIT key and offers the possibility to adjust the horizontal and vertical ampli- tude of the white image with the control disc. 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 period, 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 stick forward or back ward 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.
-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 situa- tion 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 set- ting 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.
