    ESD and handling boards: Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After removing a board from its protective wrapper or from the system, place it component-side up on a grounded, static-free surface. Use a conductive foam pad if available but not the board wrapper.

    Filename restrictions The first eight letters of the filename can be anything but cannot be renamed. Each file contains a link to the next file in the sequence. FMUP does a link check before updating to ensure that the FMUP process will be successful. The first file in the list can be renamed to any filename, but all subsequent filenames must remain unchanged.
