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 bug has been fixed since July 2011. All affected carillons can be updated with a free Management Suite download.
