Hello:
We have ten uTrack24 untis at our university and suddenly in one of these units the display backlight has dimmered almost without illumination.
On the other side we have another unit with folder button off. Although it works the led light is off.
All the units are upgraded to the latest firmware, but as there is no option visible in the menus to higher the contrast of the display or in or off a button led, is there a way to do it? Or perpaps is a unit fault?
All teh units are under warranty and these issues appear only in two units with the same hours of work at classroom.
Thanks in advance
