Question about FM for freedom and N5 speech processor.

[krazykatkitty]

I found my Phonak Smarklink SX FM equipment and stuff in a box. I used to wear FM for my 3G speech processor back in high school days and used quite a lot in junior high years. I haven't used it since I upgraded freedom. I am wondering if it compatible with the freedom and N5? I haven't got a special adapter to plug mircolink thingy for freedom and n5 I might going to the course sometimes this year and it might be useful? or I don't need it?
