I have a 898c SI. I went into H/B PC and installed my card from the finder in the reader and when the info came up , the info was wrong. H/B PC said that I had an 858c SI and had the wrong ser #. So I went to the H/B web site to check my registration and it had 898c SI and the right ser #. I called H/B and am looking foward to what they say.
