How to reset EZ Command controller???

[schloob]

Is there a way to "reset" the EZ Command controller? I'm looking for the instructions but the issue that is happening is that when you place an engine on the track now it just automatically goes. The dial does not seem to matter, it's like it is stuck on one speed. Tried unplugging/replugging, etc. Unfortunately I do not know what was happening at the time as it is my son's layout, I just come home and was told it is not woorking. Joy. Any help/advice is appreciated.

EZ Command instructions are located under "Parts, Service, & Information" on the top banner.
