Activating Proto-Sound® 3.0 Conventional Mode Features
Proto-Sound® 3.0 features are activated by sequences of Bell and Horn/Whistle
button pushes described below. Please read the full descriptions of each feature
before using it. To use these buttons to activate features rather than to blow the
horn or ring the bell, you should tap the buttons very quickly with a ½-second
pause between button presses. You may need to practice your timing to make
this work smoothly.
