An issue with some 2011 model year Millennium carillons made the keyboard stop responding after Daylight Time begins.
Try this reset procedure if the system stops playing from the keyboard:
- Go to Setup Menu - Keyboard Sensitivity (Enter 3 Enter 6 Enter)
- Make sure lower line says Light:1 Heavy: 8
- Exit the setup menu (Enter)
- Go into the keyboard mode and verify that it works.
This is an anomaly related to the DST adjustment that was patched in version 0511 firmware, and fixed for good in 0711.
All affected carillons can be updated with a free Management Suite download.
