ter 6).
With the old Motorola* format, as well as the
Delta** system, it can be run, but no sounds can
be called up.
4. TROUBLESHOOTING
1. The loco will run forwards / backwards as normal
but the lights are off:
This is correct, dictated by the system for DC
operation.
For DCC operation, the Sound decoder has been
pre-set at the factory for 28 speed steps. Probably
the running of the loco has been set to 14 steps.
Simply re-set the equipment to 28 steps, or re-
program the Sound decoder to 14 steps (see CV29
in chapter 5).
2. The loco sound is not clear:
Run the loco in pure DCC- or Motorola*-operation.
3. The loco does not respond to Motorola* com-
mands:
If the decoder is set to handle the long DCC-
address, then you must change the setting to use
the short address (CV29, bit5 = 0).
