I was just wondering if i need to use this adapter when doing the check. It seems like i should, but i've never used one so i figured i'd ask first. thanks.

Yes, use the one in the big pic.

 

the pics are both the same size??? but from what i do understand, your saying yes to using the adapter, right???
