Alarm: 486 USB TIMEOUT OCCURRED
Haas Alarm Description:
The USB firmware experienced a timeout. This can occur if the USB media is extremely fragmented, or if there are many files in the directory. Try a faster USB. Defragment USB using Windows disk tools, or a USB device with fewer files on it. If this problem persists, call your dealer.
