MM2001 reset (or not...)

[Jalex]

Hi all:

Any one with mm2001 experience???
I´ve finished the mm2001 card, motors moving correctly, and in manual
mode the +B and -B buttons increase and decrease wire temperature.
After testing some scrap material and reducing temperature to a
reasonable level pushed both B button simultaneusly.
Now I have that lower value stored.
But... can not get back to the original upper limit ( 99 % ) when
reseting the card.

Which is the right way to do so ?
I´ve tried with the reset and -B simultaneus, either one first, card
power on and off, but nothing changes.
May this be a pic program problem?
