Thank you, responder's, for the "heads up".
Yes, I looked at the Electronics and Televisions sections in the Heartland Owners Manual, just as you did. I couldn't believe there
was no Summit television even listed. I guess China flooded the market with these televisions, especially within the RV, and
Educational institution sectors, i.e. dorms.
I will call Heartland to try and get the information, and then send update to the link to include in the tools section for other's.
