reset to factory setting of Bachmann DCC decoders

[traintronic]

Hello,
I have several Bachmann locomotives with DCC. ( EMD FT A units, Baldwin Sharknose A & B units) After programming the address to a number other than 3, the locomotives no longer run on regular DC. How do I set the decoders back to factory default?  Some other decoders are reset by programming CV 8 to a value of 8, but that doesn't seem to work with the Bachmann decoders. I use MRC Prodigy Express.
