Notes on how to update the firmware on your Concept2 PM5 monitor. Key takeaways: 1) Don't touch the buttons after plugging in a USB drive for a firmware update. Just let the firmware try to boot from the USB. 2) If using a USB drive, make sure it's FAT or FAT32 formatted and I believe it needs to be 16GB or smaller. I could not get my 32 GB FAT32 USB Drive to work. 3) A USB cable from an old printer works well for transferring the firmware to your PM5. Using a cable worked for me.
