Automatic Sound Effects

Certain Proto-Sound 3.0 sound effects automatically play in programmed
conventional mode conditions:
• Squealing Brakes play any time the engine's speed decreases rapidly.
• Cab Chatter plays at random intervals when the engine idles in neutral.
• Engine Start-up and Shut-down sounds play when the engine is initially
powered on or is powered off for five seconds or more.
Command Operation
• DCS - MTH Proprietary Digital Command System
• DCC - Digital Command Control
To get the DCS and DCC instructions, download the instruction manual from the
Proto-Sound 3.0 engine files used.
Note: The DCS/DCC switch must be in the proper position. The DCS position
provides continuity through the switch.
