The Sector 7 HHAB (Kyr'Ozch Nano Protection Ring) currently does not follow normal OE rules and requires you to be at or above the equip requirements (400 sense/psychic) for it to add its Nano Resist (and I believe all the other) modifier(s) to your stats. If you are below the equip requirements (even if you are above OE), the ring is greyed out does not add any NR at all. I believe this is caused by the same issue described by Metaing here (although Metaing was referring only to the Zone Protection modifiers on the normal/profession HHABs in that post).
Working as intended™?

EDIT: I believe it might be base 400 sense/psychic for modifiers to be applied?
EDIT2: Apparently the Experimental Cyborg Token Board might have the same issue. Credatz to Makihran for the find.
