™Proto-Coupler OperationThis locomotive is equipped with one or more coil-wound Proto-Couplers for remote®uncoupling action. Because Proto-Couplers are controlled through the Proto-Sound3.0 microprocessor, they do not require an uncoupling track section or modification toyour layout to function. You can fire a coupler from neutral or while in motion. Usethe code shown below (and in the chart on p. 21) to fire the coupler(s).Rear Coupler:To fire the rear coupler, quickly tap the Bell button once followed by three quick taps ofthe Horn button, allowing approximately ½ second to lapse between each quick buttonpress. The sound of the liftbar and air line depletion will play, and the knuckle will bereleased.Front Coupler:To fire the front coupler (if your engine has one), quickly tap the Bell button oncefollowed by four quick taps of the Horn button, allowing approximately ½ second tolapse between each quick button press. The sound of the liftbar and air line depletionwill play, and the knuckle will be released.Horn Horn FireRearCoupler=HornBellHorn Horn FireFrontCoupler=Horn HornBellTips 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 goingwhen 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 thethrottle 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 strainto 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 inmotion except that, at the conclusion of the PFA, the engine will depart in the nextdirection of travel, as opposed to the direction it was traveling before entering Neutral.RailKing 4-8-8-4 Big Boy Steam Engine12
