F21 Feature Reset
Resets the engine back to factory defaults with the exception of the address.
F22..F25 Idle Sounds 1 - 4.
Plays what we call idle recipes 1 through 4. These sound sequences play randomly
when the engine is at idle but if you have these F functions, you can trigger them
whenever you like.
F26 Brake Sounds
Toggles brake sounds between auto and off. They are on by default but you can
turn them off.
F27 Cab Chatter
Toggles random voices between auto and off. They are on by default but you can
turn them off.
F28 Clickety-Clack
Toggles the sounds of sustained speed inside a passenger train between auto and
off. This sound is off by default but you can turn it on (auto). Once on, if you
maintain a steady speed of ~30 smph or higher for more than 30 seconds, the effect
automatically turns on.
