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/horn 
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, FYS 
starts.

The Proto-Coupler won’t let the 
engine uncouple on the fly.

The coupler does not fire or stay 
coupled.

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/horn button more slowly, 
taking approximately one full 
second to fully depress the button.

You may be pressing the button 
too quickly. Try pressing the bell 
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.

The coupler needs to be cleaned.  
Wipe with denatured alcohol (not 
rubbing alcohol) and let dry.

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.
