!FYS/PSA will continue, and within a few seconds, the engine will start and move out on its
own at the current throttle setting, in the same direction it was traveling when you began
the sequence. Once the bell turns off, the operator regains control of the transformer's
Bell and Horn/Whistle buttons and can ring the bell or blow the horn/whistle as usual.
Tips on Using FYS/PSA
!You can terminate FYS/PSA at any time by turning off power to the track for
15 seconds.
!You do not have to be in Forward to use FYS/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 FYS/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 FYS/PSA. Otherwise, the engine without FYS/PSA will begin vibrating
on the track as its motors strain to move the train, since they cannot be
automatically disabled during the FYS/PSA cycle (or if an original Proto-Sound
engine, FYS/PSA are triggered differently and that engine's motor-disable feature
will not be active when you run FYS/PSA in Proto-Sound 2.0).
!FYS/PSA can be triggered from Neutral. It will operate the same as if triggered
while in motion except that, at the conclusion of the FYS/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 page 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/Whistle 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.
