17. File Operations
The switcher is capable of storing operational data to USB flash memory and also of recalling and
downloading previously saved data for application to production operations. Operational data
including system settings, wipe settings, stills, bus settings and events can be all saved to and
downloaded from the USB flash memory.
17-1. USB Flash Memory
For available USB flash memory, see "Available File List" in the Appendix. Inserting and
removing of USB should be performed slowly and firmly.
The access lamp on the USB flash memory blinks while saving or reading data. Check
access to the USB flash memory before and while performing the operations. Do not remove
the USB flash memory while the access lamp is flashing. This could corrupt the stored data or
damage the USB flash memory.
The remaining space of the USB flash memory is displayed at the bottom right-hand side in
the FILE menu.
