*1: Even when using a PC with adequate specifications, capture errors occur at times because the PC is in bad condition.
        (For example, when other applications are open, or recording medium has no free area.) When you capture data
        using this software, please close all the other applications and save captured data to the hard disk.
*2: Don’t start up other applications while this software is operating, and don’t perform multiple operations. (For
        example, screen saver, virus scan program, copying and moving files, searching files, etc.)
