FirmSafe makes it safer to import new software: The firmware on the device is not simply overwritten, but a second firmware is stored in the device in addition (symmetric FirmSafe). This protects your device in case of events such as a power failure or an interrupted connection during the firmware upload.
Only one of the two firmware versions stored in the device can be active at any time. When new firmware is uploaded, the currently inactive firmware version will be overwritten. By selecting the FirmSafe mode you decide which firmware version should be activated after the upload.
