I went to radio shack and got a 3V Lithium battery and instaled it
in my poly 800. Though some features seem to be working
better, it is still kinda messed up.
Since the battery replacement, I can now program patches
however, it dosn't seem to save them after I power down. The
tape interface dosn't seem to be working as well(keep getting
errors) I think that the problem is deeper than the internal battery.
