Pro 2036 can pick up cell in the 400-512 range with this mod. Find IC 11, locate it on the bottom of the main board(where its pins come through).
Cut the trace between pin 7 and the base of Q17 and solder a wire to pin7 and base of Q17. Cut the trace between pin9 and the base of Q18. Solder a wire to pin9 and the base of Q18. Then solder one more wire to pin8(ground).
You now need a dual pole dual throw switch (6 leads on the underside) Solder the free wire ends in this order.
pin9 o o base of Q17
base Q18 o o pin7
