Start-up
When I apply power to the track my
engine doesn't do anything. No lights,
no sound, no nothing.
I get an error when I hit Start-Up
DCS is polarity sensitive when
powered by a DC power supply.
Sound
When I press the Whistle Button on
my DCS remote or DCS commander
the whistle doesn't blow
I have no sound on my engine, but my
lights are on and it moves just fine
There's a crackling sound from my
tender
When I run Doppler I can hear the
Doppler shift but then the engine
sounds fade out and I can't get them
back
DCS (Remember, it's NOT DCC)

This is normal. You have to hit the Start-Up
button.
Check to see if that section of track has power.
Use a voltmeter or a lit passenger car, not your
tongue.
Slide the engine a couple of feet in either
direction, you may have a bad track section
Have you got that section electrically isolated
with a toggle switch or other device?
Have you recently changed the engine address?
Check if there is power on that section of track
the engine is sitting on (there has to be power for
the signal to get to the engine and for the engine
to be able to hear it)
Check the polarity of the DC power supply
connected to the Fixed 1 or Fixed 2 Inputs. Shut
down power, reverse the inputs and repower
DCS. Hitting the startup button the DCS remote
should start up the locomotive.
If you have two engines on the track they both
may have the same address. Take one of them
off the rails and try it again
Check if the playable whistle is active. On the
DCS Commander there will be two dashes on the
right side of the LCD if it's active. Press "A1"
twice to ensure it's turned off. On your DCS
remote press the "SPW" button twice to ensure
it's disabled
You may have it turned off. Repeatedly press
VOL + to bring the Master Volume up
Did you turn off the ENG Sounds? Press the
ENG SND button on your DCS controller.
Check that you haven't lowered any of the
independent engine volumes (Eng Sounds, Bell,
Whistle, or Accent)
Check to see if a screw or some other material
hasn't lodged itself in the underside of the
tender.
This is normal. You will need to press the
Doppler button again to turn Doppler off. Your
engine sounds will now return to normal
