[Pro2006] Flashing battery warning and beeping

Hi Edgar,

That is so funny; I had exactly the same thing on my Pro-2005 (see original 
message copied at end).

In my case, the 9V battery wires and connections were fine. I re-soldered 
the pass-throughs and some obvious connections, but that didn't help. 
Finally, I found one broken trace on the circuit board and ran a jumper over 
it. That fixed it.

If you can solder with a soldering pencil (not a soldering gun), and have a 
test meter (DVM) that will check continuity (if two things are electrically 
connected), you can probably fix it yourself. Knowing how to test diodes (as 
George described) might help too.

You will also need the low battery circuit schematic, which I just tried to 
upload to the group but apparently I'm not a member (?). I can email it to 
you if you'd like, it's 318K.
