The UDC 3300 performs background tests to verify data and memory
integrity. If there is a malfunction, an error message will be displayed. In
the case of more than one simultaneous malfunction, only the one with the
highest priority will appear on the lower display.
A list of error messages is contained in Table 5-5. If any of these error
messages occur, refer to Section 9 - Troubleshooting for information to
correct the failure.
