HI Frederick,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
Not sure, but look around the front area where you hook up the TV for the bedroom, maybe even in the closet. I'm sure some of our other members will jump in soon with some suggestions also.
Be sure and check out our Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum and your new to you unit.
Jim M
