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.

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.
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.
