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 de pletion will play, and the knuckle will be
released.
