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.
Reset to Factory Default
To override the settings you currently have assigned to the engine and reset it to its
factory defaults, while in Neutral tap the Horn button quickly once, followed by five
quick taps of the Bell button, allowing approximately ½ second to lapse between each
quick button press. Two horn blasts will indicate that the engine has made the change.

Conventional DC Operation
Your MTH locomotive will operate on conventional DC track voltage also. However,
functions such as blowing the whistle, ringing the bell, and the PSA sounds cannot be
initiated in conventional DC. Only the steam chuffing sounds with synchronized
puffing smoke, squealing brake sounds, and idle sounds will function.
Operation of your MTH Proto-Sound 3.0 engine in conventional DC is very similar to
operating a conventional AC engine. As you increase track voltage, engine speed
increases.
As the track voltage is decreased, engine speed is decreased. When track voltage polarity
is reversed using the polarity or direction switch on the power pack, the engine will run
