Quoted from Jeff_PHX_AZ:Question, do you erase the new update that happen a couple weeks ago to add this new update? So correct me if Iam wrong, when I unbox and setup, the first thing before turning the machine on is putting the usb stick in to upload1.5v, with this new code 1.51v it will erase the 1.5v or just add to it?
The updates are not incremental. When your machine arrives you will want to check for the latest code and download that onto your USB stick. If there are multiple versions on your stick you can choose which one to load.
The process on my pro is to flip dip switch 8 then press the reset button or reboot by powering off and on (the reset button is easiest). You will then select the code to load and then go for a beer or something while it updates (this will take some time).
When done you flip dip switch 8 back to it's original position and reset again to reboot into the new code.
