Replacing the HDD

In case of a malfunction, the original hard disk can be exchanged for a Compact Flash card. Make sure that the replacement card supports the ability to be used as a "fixed disk". Usually these are called "industrial grade" cards. "Consumer grade" CF cards are usually detected as "removable drives" and won't work in the scope. Since the scope supports FAT16, the maximum partition size is roughly 4GB.
