Activating Proto-Sound 3.0 Conventional AC Mode Features
Throttle
- To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while turning
counterclockwise will decrease voltage and speed. The engine will maintain the speed
you set after you release the throttle until you turn it again to change the voltage and
speed.
Bell
- To sound the bell, in an engine equipped with a bell firmly press and release the
Bell button. To turn the bell off, press and release the Bell button again. The bell will
continue to ring from the time you turn it on until you press and release the button
again to turn it off.
Horn/Whistle
- To sound the whistle, firmly press the Horn/Whistle button. The
whistle will sound for as long as you continue to depress the button. It will stop when
you release the button.
Direction
- Your train is programmed to start in neutral. The train will always cycle
neutral-forward-neutral-reverse with each press and release of the direction button.
The engine is programmed to restart in neutral each time the track voltage is turned off
for 25 seconds or more.

Subsequent interruptions in track power of 1-2 seconds will continue the sequence
rotation. If you happen to interrupt track power for longer than about 2 seconds, the
engine will begin its shut down sounds. If this occurs you can cycle the direction
sequence again to get back to the direction you wish to move and once the engine starts
moving its shut down sounds will stop playing (see direction cycle phases).
In conventional AC operation the whistle sound, the bell sound, PFA sounds and other
operational functions can be accessed if your transformer has a horn/whistle button and
a bell button. By using combinations of button presses, different commands besides
blowing the whistle and ringing the bell can be initiated.
