Chris,
With your RM mixer, you can see if there are update every time you log into your user account. A red numerical indicator will be present when there is a new Firmware Update for you mixer. While you are logged into your user account, you have the ability to download the firmware right then and there and then take it to your practice space when time permits. We suggest that you go ahead and have a proper USB flash drive setup, formatted properly and then you can unzip the firmware files as described in the documentation on how to update you consoles firmware. Then, all you would need to do is to complete the update process when you get to the mixer.
