I took the back off the tp2 and took the battery out underneath the fcc seal there is a very faint thin grayish white line of letters about 1/16" high if that, against a light gray background. need to use a magnifying lens and a light held at an angle to read it. very faintly it does say rhod400. but not on the white sticker with the 3 lines of barcodes on it.
thank you for your help! was that quote in the fine print at bottom of FaQ?
