unfortunately, there's no owner's manual that will help you with your specific trailer.
nearly all RV manufacturers only provide a generic owner's manual, that only covers RV systems and procedures.
none have any model-specific info.
the FR generic manual is available on the forum, for download.
hopefully, someone with your model can help.
it's also helpful if you post pictures of what you're talking about.
