How do you turn off the smoke unit? Printed the manual (Proto-Sound 2.0) and it reads, "turn off the smoke unit switch located under the tender body"; but I don't see a switch. The engine has Proto-Sound 3.0 but I don't see a manual on the MTH website I can print. Is there a difference in the Proto-Sound versions?
Update...Found it located under the cover on top of the tender. Hey MTH, I would like to see an updated manual for this set.
