Hello Kenny Winters,
Sorry, you did not receive that information.
If that model does in fact have an HDMI port, you can use a splitter, you will need 2 x of the Mini HDMI to Standard cables and then an HDMI splitter.
However, there are a few variations of that NordicTrack.
Alternatively, some people are just configuring Casting to the second screen, if it is an older TV you may need to add a Chromecast device to it.
Different model but the casting should be the same – https://www.youtube.com/watch?v=cWUUUlRmAU8
I hope this helps!
