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 sounding the horn, ringing the bell and the PFA sounds cannot be
initiated in conventional DC. Only the diesel engine sounds, smoke, squealing brakes
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
in the opposite direction. The electronics in your MTH Proto-Sound® 3.0 locomotive
are designed to slowly change direction without a need to change the throttle, if you so
desire.
Just change the polarity switch on your DC power pack and the engine will gradually
come to a stop and then automatically begin traveling in the opposite direction. The
speed will build up to the same speed that the engine was going in the previous
direction. When power is first applied to the locomotive, the engine’s sounds will start
up when the track voltage reaches about 8 VDC. To get your locomotive moving, after
the startup sounds have finished and the locomotive is idling, slowly increase the track
voltage until the locomotive is traveling at the desired speed.
