Bluetooth can be used to transfer files to and from the Carlson RT3 and RT4. After turning off the default "Tablet" mode
on the Carlson tablet (by tapping on it in the Action Center that appears when swiping from the right edge of the
screen), you can then tap on the Bluetooth icon in the bottom-right system tray and select "Receive a File" from the
menu. While that screen is open, you can then use the related "Send a File" menu option on another computer to select
and transfer a file to the Carlson tablet. This same procedure can be performed in the other direction as well.
