roll_the_dice posted:OK, another questions...if I need to start a new thread I will...but here goes. Should I reset the HandHeld back to factory defaults with a used 990? If I do, will that do anything to the software version? Thanks!
you mean by pushing the reset button on the back of the handheld?
because nothing is stored in the handheld and the program is hard written nothing will happen to the program. I have reset many times.
