Firmware Update

Transfer all data files from the SD card and DELETE all data files on SD card before doing the firmware update! Leaving data files from older firmware versions may corrupt the SD card.

Several files should be accessed from the software CD or downloaded from the F-900 support webpage (https://felixinstruments.com/support/F-900/) under software. Always double-check the webpage for the latest compatible firmware version depending on the serial number of the F-900. Please contact Felix Instruments technical support with questions about firmware updates.
