firmware update - how to
Almost all the updates for our instruments require you to plug a USB thumb drive in the USB "A" port of your instrument.
In case none of the USB drives at your disposal work,I suggest buying a Kingston or a Sandisk USB drive, or even a Lacie, a Samsung.
Avoid Transcend, don't buy EmTec or any other bulk/unknown cheap drive. Every time you have to disconnect the drive from your computer, i.e. after having copied a file, use the safe removal procedure as requested by your operating system.
Be sure it is FAT32 formatted and be sure to unzip files before put them in the usb stick.
