  • Page 10: Freight Yard Sounds (Fys)

    FREIGHT YARD SOUNDS (FYS) ProtoSounds® comes equipped with operator controlled Freight Yard Sounds, hereby referred to as FYS. This easy to use feature plays digitally reproduced freight yard sounds whenever your engine stops on your layout and is parked in the Neutral position. No additional wires or modifications are needed on your layout to enjoy these amazing sound effects.
  • Page 11 carefully, you should hear an air release sound after three seconds have passed. At this time you can release the bell button. (Note: because the air release sound may be difficult to hear, we recommend that you count out a full three seconds before releasing the bell button.) The bell will continue to chime, so if you want to turn off the bell ringing, simply press and release the bell button a second time.
  • Page 12 ACTIVATING THE FREIGHT YARD SOUNDS Before FYS can be heard, the feature must be armed as described on the proceeding pages. Once armed, activating the FYS effects is accomplished by simply interrupting the transformer throttle and parking the engine in the Neutral position with track power remaining on.
  • Page 13 B. After entering Neutral, ProtoSounds® will immediately play an air release sound followed approximately 2 seconds later by a radio arrival message (cab chatter). Immediately following the radio arrival Listen For Air Release Sound And Cab Chatter Message message, the sound of freight car doors can be heard opening, followed by the sounds of freight loading and unloading.

    Event 5: (Forward) The operator now interrupts the transformer throttle again to enter the next reverse unit phase; Forward. FYS confirms to the operator that it has entered the Forward phase by playing a radio messagne followed by the freight car door closing. Within 2 seconds of the door closing, the locomotive bell begins chiming.
  • Page 15 Tip #4: You can utilize FYS even if you are double-heading with another engine regardless of whether the second engine is equipped with an FYS programmed ProtoSound® module. If the second engine isn’t equipped with FYS, the only thing to remember is that you not turn up the transformer throttle very high when entering the Reverse phase found in Event 3.
