2 steam DCC questions

I picked up 2 steam engines at a train show today. One is a Broadway Paragon PRR K4, works on DCC, doesnt do anything on DC. I know you can lock out the dual mode feature. What CV is it so I can turn the duel mode back on? I need the duel mode right now. I also picked up a late run Proto 2K NKP Berk with mars light, but no DCC/Sound. The mars does its proper flashing thing. Will puting a simple TCS decoder in mess this up? Or am I going to have to go the full sound route with either QSI Revolution or Tsunami to keep the mars working? Thanks in advance. Mike

Programme CV29 with a value of 38 in the Paragon K4s.

I am sorry, but I won’t be able to help with your other question.

Thanks for the programing tip, I am taking the K4 to a buddies house with Digitraxx and decoder pro and will correct the CV so she will run in duel mode again. Thanks Mike.
