The sound project loaded into this decoder can be operated independently of any other DCC motor or function decoder. If another non-Sound FX compatible DCC decoder is connected to the track leads then CV readback of SFX064D Sound CV's and PR2/PR3 SoundTest modes may not be possible.
Note that it is always possible to Write CV values using Operations mode or a Service Mode programming track, even if CV Read is inoperative.
If the connected function loads are insufficient for CV readback or an incompatible DCC decoder is also connected, it is still possible to download a complete sound project by using the large green program project icon in the SoundLoader program.
