TROUBLE SHOOTING

This decoder should perform well with all DCC systems. The maximum DCC output
should be less than 16 V. If the locomotive does not respond to commands, it may
have lost its address. Please re-program the address and program CV19 to 0
(disable consist). If it responds  slowly, you should clear its momentum by
reprogramming CV3 and CV4 to zero. If step 1’s speed is too high, you should
program start voltage, CV2 to zero. If its top speed is too slow, program top
voltage CV5 to 31. You should also clean the track to improve electrical pickup.
Read your DCC system manual to learn how to program and operate the decoder.
For more information about registers/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

. Whenever the

decoder doesn’t work please use the program track to program CV# 125 with
value 1 to restore the decoder to factory settings. This should bring the decoder to
life with address #3.
