Alco FA2 sound value

[Fernando]

I got a nice Bachmann FA2 Soundtraxx equipped. Tsunami manuals - user's guide and diesel technical reference - don't show CV5 (V max) and CV6 (V mid) unlike the Sountraxx link http://www.soundtraxx.com/factory/OEM_pages/bachmann/ho_fa2_sv.pdf, so don't know whether or not they are included and progammable.
Otherwise, the loco often stops and flash lights. I use Roco Multimaus and don't know whether or not there is any incompatibility between this system and the Tsunami. 
If anyone can clarify me on these subjects I would appreciate.
