Page 6 Screens Rear projection screen requirements Viewable from all angles High contrast Focused Minimal reflection Cleaning of screens : Avoid to touch screens !!!! See user manual for cleaning instructions.
Page 7 Screens Screens can be mounted in different ways. Expand/shrink due to temperature and moisture Canned –Minimal gap between screens –Visible gap –Only 50” and front access 70 “ Canned – seamless –No gap –Screens push against each other –Only 50” Stitched –Small needle like wires hold the screens together –No gaps –Only from 70” onwards

Page 13 Lamp cut-off voltage – lamp retry When lamps get older they can Simply stop working and refuse to start again Explode…… : no danger ! Graph not representative, for illustration purposes only !
Page 14 Maintenance actions -Defective lamp : -Retry lamp first (reset error + reselect lamp) -When fails again (same day) -Replace lamp -Lamp warm-up – wait 2 min. -Optimize the new lamp! (only possible in service mode). Air Filter Replacement -Dependent on Contract and/or Need -Don’t shake the dirty filter -Dispose used filters – DO NOT CLEAN
Page 15 Components : Typical delays & button functions Cooling / warming : 2 min Color stabilizing : 5 min Overtemp before shutdown : 5 min On/Res button: Up –1-3 sec: switch on from standby –4-8 sec: toggle between IP address and error status –> 10 sec: reset lamp error Down –1-3 sec: switch to standby –4-8 sec: not used (yet) –>10 sec: self diagnostic of IU

Page 25 BCM: Brightness Lock 3 basic modes: Uncalibrated –Brightness locking not active so dimmer wheel stays in last known position. –Color correction not active so native colors are shown. Brightness locked –The brightness is dynamically controlled with the dimmer wheel by using only the brightness information of the color sensor. The colors are static. Sense 6 (License required, see BLM) –Next to Brightness, color is also dynamically controlled. This is done with the DMD chip.
