At power up, the CR800 loads default.cr8 if no other program takes priority (see Program Run Priorities (p. 106) ). Default.cr8 can be edited to preserve critical datalogger settings such as communication settings, but cannot be more than a few lines of code. Downloading operating systems over telecommunications requires much of the available CR800 memory. If the intent is to load operating systems via telecommunications and have a default.cr8 file in the CR800, the default.cr8 program should not use significant memory, such as occurs by allocating a large USR: drive, or by using a DataTable() instruction with auto allocation of memory. 105
