When I first turn the power on, the
engine will not begin to run. I have to
turn the throttle off and then on again
to get the engine to operate.
When I press the whistle button, the
bell comes on instead.
I can’t get the horn to blow when I
press the whistle button.
I can’t get the bell to ring when I press
the bell button.
The bell won’t work on a separate bell
button.
When I try to fire the coupler, PSA
starts.
The Proto-Coupler won’t let the engine
uncouple on the fly.
When I press the whistle button, the
bell sounds.
Reverse the transformer leads.
You may be pressing the button too
quickly. Try pressing the whistle button
more slowly, taking approximately one
full second to fully depress the button.

Reverse the transformer leads.
Check the wiring of the separate
button.
You are waiting too long between
whistle button presses.
Try lubricating the coupler knuckle
with a dry graphite lubricant. Do NOT
use oil.
This is normal behavior. To prevent
accidental high-speed start-ups, Proto-
Sound 2.0 is programmed to start up
in neutral anytime track power has
been turned off for several seconds.
See the "Basic Operation" section for
more details.
