Hi,
Looking at things, I believe it will be the lower one. As mentioned, the manual is a bit confusing. However, it makes more sense to me that it would be the lower one.
I wish I could give you a 100% response, but I can't tell for sure based on the manual.
Let me know what you find or if you have questions.
Take care,
Joe
