Although Proto-Sound 2.0 has been designed and engineered for ease of use, you may
have some questions during initial operation. The following table should answer most

Starting Up
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.
Whistle/Horn
When I press the whistle/horn button,
the bell comes on instead.
I can't get the horn to blow when I
press the whistle button.
Bell
When I press the whistle button, the
bell sounds.
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, FYS
starts.
The Proto-Coupler won't let the engine
uncouple on the fly.
The coupler does not fire or stay
coupled.
