M.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities that
allow the engine to maintain a constant speed up and down grades and around
curves, much like an automobile cruise control. You can add or drop cars on the
run, and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature activated,
you can opt to turn it off. This means the engine's speed will fall as it labors up a
hill and increase as it travels downward. It is also affected by the addition or
releasing of cars while on the run. Because the engine will run more slowly at a
given throttle voltage when speed control is on than when it is off, you should
adjust the throttle to a lower power level for operation with speed control off to
avoid high-speed derailments. When speed control is off, the volume will drop to
allow for better low voltage operation.
To turn speed control on and off
, put the engine in neutral, then quickly tap the
tranJ1eormer's Horn button one time then quickly tap the Bell button two times,
allowing approximately ½ second to lapse between each quick button press. Two
horn blasts will indicate that the engine has made the change. Repeat the 1 horn, 2
bells code to return it to the other condition. You will want to do this during the
initial neutral upon start-up if you ever couple this engine to another engine that is
not equipped with speed control to avoid damaging the motors in either engine.
Each time you shut down the engine completely, it will automatically turn speed
control on.

Locking Locomotive Into A Direction
You can lock your engine into a direction (forward, neutral, or reverse) so that it will
not change directions. To do this, put the engine into the direction you want (or
into neutral to lock it into neutral), run it at a very slow crawl (as slowly as it will
move without halting), and quickly but firmly tap the Horn button once followed
by three 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. The engine will not change direction (including going into
neutral) until you repeat the 1 horn, 3 bells code to return the engine to its normal
condition, even if the engine is kept without power for extended periods of time.
