Hi Pam, a 4-5-6 reset would have no detramental affect, because the new build of KeySoft is burned into the ROM of your BrailleNote.
If your unit is not freezing at randem, then you probably don't need to worry about the new build. Jonathan Mosen BrailleNote Product Marketing Manager HumanWare DDI: +1-925-566-9265 http://www.humanware.com
