TROUBLE SHOOTING
The MRC 0001634 HO diesel sound decoder should perform well with all DCC
systems. See your DCC system manual to learn how to program and operate the
decoder. For more information about register/CVs and their functions, please refer
to the NMRA DCC Standard & Recommended practices, RP-9.2.2 this is available
directly from the NMRA or their website at
www.nmra.org.
Due to the nature of all sound decoders, the CV read back is not 100% correct. So
this feature is not supported in the decoder. This is not a defect of the decoder or
your DCC system.
Whenever the decoder doesn’t work please use program track to re-program the
loco address or program CV# 125 with value 1 to restore the decoder to factory
setting. This should bring the decoder to life.

This device complies with the part 15 of FCC rule. Operation is subject to the
following two conditions. (1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
