Tips on Using PFA
•You can terminate PFA at any time by turning off power to the track for 15 seconds.
•You do not have to be in Forward to use PFA. At the conclusion of the full sequence,
the train will pull away from the station or yard in whatever direction you were going
when you activated the feature.
•You can use PFA even if you are double-heading with another engine. If the second
®
engine is not equipped with Proto-Sound 3.0, you must remember not to leave the
throttle at a high voltage level once you have stopped the engine to run the PFA.
Otherwise, the engine without PFA will begin vibrating on the track as its motors strain
to move the train, since they cannot be automatically disabled during the PFA cycle (or if
®
an original Proto-Sound engine, PFA are triggered differently and that engine's motor-
®
disable feature will not be active when you run PFA in Proto-Sound 3.0).
•PFA can be triggered from Neutral. It will operate the same as if triggered while in
motion except that, at the conclusion of the PFA, 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 3.0 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.
25) 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 depletion will play, and the
knuckle will be released.
Front Coupler (Not Included):
To fire the front coupler (if your engine has one), quickly tap the Bell button
once followed by four 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 depletion will play, and the knuckle will be released.
