Proto-Sound 2.0 Operating Instructions
This manual contains the operating instructions for Proto-Sound 2.0 in conventional
mode only. Instructions for accessing DCS command mode features accompany the
DCS Remote Control System equipment.
Activating Proto-Sound 2.0 Conventional Mode Features:
Proto-Sound 2.0 features are activated by sequences of Bell and Horn 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.
Freight Yard Sounds (FYS):
Your engine is equipped with a sound package of freight yard sounds that you can play
when you pull into a yard. Each sequence described below will play as long as it is left
on, randomly generating sounds, but be sure to allow approximately 30 seconds between
the button pushes described below to allow the FYS sufficient time to run through each
sequence.
• To cue the sound system to play the FYS, quickly but firmly tap the Bell button once
followed by 2 quick taps of the Horn button while the engine is moving. Tap the buttons
quickly but allow approximately ½ second between each press.
• Press the Direction button once to stop the engine. This will trigger the first
sequence of FYS. The reverse unit is temporarily disabled so that the train will not move
as you use the Direction button to trigger the sounds, and Proto-Sound 2.0 has disabled
operator control over the Horn and Bell buttons until the full FYS sequence is complete.
After waiting about 30 seconds for that sequence to run, press the Direction button again
to trigger the second sequence of FYS.
• After about 30 seconds, press the Direction button again to trigger the third
FYS sequence.
• Again, after allowing about 30 seconds for that sequence to run, press the Direction
button one more time to trigger the fourth and final FYS sequence. The FYS will
continue, and within a few seconds, the engine will start and move out on its own at the
current throttle setting, in the same direction it was traveling when you began the
sequence. Once the bell turns off, the operator regains control of the transformer's Bell
and Horn buttons and can ring the bell or blow the horn as usual.
