Duringthe start up a warm up menu will displayed. This menu offers thepossibility to skip the warm up periode anyway by pressing the EXITkey and offers the possibility to adjust the horizontal and verticalamplitude of the this white image with the control disk. During thiswarm up period, a full white image is shifted on the CRT faceplate toavoid a burn in.Every 30 seconds a text box will be displayed on another place on thescreen with the remaining time to go.When EXIT is pressed during this warm up periode, the warm upmenu will be redisplayed with the remaining time indication. Pressanother time EXIT to interrupt the warm up cycle.When the warm up option is OFF, when switching on the theprojector, it starts immediately with the projection of the selectedsource.CRT Drive ModeThe projector CRT's can be driven with the normal current (normalmode), a lower current (economic mode) or with a higher current(boost mode).To change the drive mode, highlight 'CRT drive mode' by pushing thecontrol disk up or down and press ENTER to display the CRT drivemode menu.Select with orthen to return.SERVICE MODEG2 ADJUSTMENTGAMMA CORRECTIONSCRT RUN IN CYCLEPROJECTOR WARM UPCRT DRIVE MODEMORE...CRT DRIVE MODENORMALECONOMICTEMPORARY BOOSTPERMANENT BOOSTWARNING : permanentboost mode reduces the lifetimeof the CRT's !Select with orthen to return.To change the boost mode, push the control disk up or down to selecta 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'swill enlarge but the light output will reduce.- Tempory boost : higher drive current to the CRT's, the lifetime of theCRT's will shorten but the light output will be higher. This situationis 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 ofthe CRT's will shorten but the light output will be higher. This settingwill be saved in the EEPROM. When restarting the projector, it willstart up in boost mode.A warning, permanent BOOST mode in use, will be displayed toinform the user.When text is on, this warning will be repeated every time a newsource is selected.WARNINGPERMANENTBOOST MODEIN USE !
