Please appreciate :

- a day or (many) more of work on each unit
<< I have tested your recorders to the absolute maximum - many, many days of recording and playing back each, and both are working perfectly. >>
<< The Hi-MD units are a great deal more difficult to work on, and the testing takes so much longer because of all the different recording modes. Plus there always seems to be something else to do! >>
