5 = 50 inch
7 = 70 inch
8 = 80 inch
10 = 100 inch
RR = resolution
– 08 = XGA = 1024x768 = 786 000 ~ 8
– 13 = SXGA = 1280x1024 = 1 310 720 ~13
– 15 = SXGA+ = 1400x1050 = 1 470 000 ~15
f = front accessible

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.

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

Lamp cut-off voltage – lamp retry
When lamps get older they can
Simply stop working and refuse to start again
Explode…… : no danger !

Maintenance actions
- Defective lamp :
-
Retry lamp first (reset error + reselect lamp)
When fails again (same day)

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

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.
