If you don't want to wait for the snail mail you can download a manual from whiteselectronics.com. I have a downloaded manual I keep in the car for both the DFX & XLT for reference without having to turn my original manuals into confetti.
Although it's not an issue with the MXT but the manuals for my machines have the original factory programs found in the custom programs slots & it's always good to refer back to them on occasion.
Have fun with the MXT & I hope you find lots of neat things with it.
Jeff Foster's books are really great! They go into a lot more detail than the owner's manual.
Still waitin' for that song.
