Tips on Using PSA
•You can terminate PSA at any time by turning off power to the
track for 15 seconds.
•You do not have to be in Forward to use PSA. At the conclusion
of the full sequence, the train will pull away from the station in
whatever direction you were going when you activated the feature.
•You can use PSA even if you are double-heading with another
engine. If the second engine is not equipped with Proto-Sound 2.0,
you must remember not to leave the throttle at a high voltage level
once you have stopped the engine to run the PSA. Otherwise, the
engine without PSA will begin vibrating on the track as its motors
strain to move the train, since they cannot be automatically disabled
during the PSA cycle (or if an original Proto-Sound engine, PSA are
triggered differently and that engine's motor-disable feature will not
be active when you run PSA in Proto-Sound 2.0).
•PSA can be triggered from Neutral. It will operate the same as if
triggered while in motion except that, at the conclusion of the PSA,
the engine will depart in the next direction of travel, as opposed to
the direction it was traveling before entering Neutral.

Proto-Coupler® Operation
This locomotive is equipped with one or more coil-wound Proto-Couplers for
remote uncoupling action. Because Proto-Couplers are controlled through the
Proto-Sound 2.0 microprocessor, they do not require an uncoupling track section
or modification to your layout to function. You can fire a coupler from neutral or
while in motion. Use the code shown below (and in the chart on p. 7) to fire the
coupler(s).
Rear Coupler:
To fire the rear coupler, quickly tap the Bell button once followed by three quick
taps of the Horn button, allowing approximately ½ second to lapse between each
quick button press. The sound of the liftbar and air line de pletion will play, and
the knuckle will be released.
