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.
