PRO34.9
   I suggested that a ground connection or a  circuit  board in  his
   PRO-34  might be loose.  The thin PRO-34 plastic case feels chintzy,
   and can flex easily by applying  just a  gentle  squeeze.  After
   prolonged use, the case motion can loosen screws which were once
   tight.

   Ron disassembled his PRO-34.  He unfastened  the  helical antenna,
   knobs,  and  rear screws, then gingerly removed the plastic case.
   After Ron tightened a Phillips screw holding  the  Logic  Board
   to the front of the case, the birdie disappeared forever!

   The operation took a steady  hand.   Although  he  didn't have  to
   remove any boards, Ron warned that accessing the offending screw was
   a challenge.  He used  a  very  small Phillips  screwdriver,
   positioned  through  a  hole in a shield partition.
