TIPS ON USING FYS FEATURES
FYS is a unique feature of Proto-Sound® that is completely controlled by the
operator. You decide how, when or if you want to utilize the feature. By
reviewing the following tips, you should find solutions or suggestions to the
various operating scenarios you might encounter when using FYS.
Tip #1:
You can escape the FYS sequence by interrupting the transformer
throttle before the man’s whistle plays in Stage 1 (neutral).
Tip #2:
You can exit FYS at anytime by turning the transformer throttle Off for
15 seconds.
Tip #3:
You do not have to be in Forward to utilize FYS. For example, if you
activate the FYS feature while in Reverse your train to leave the station/yard in
the same reverse direction that it arrived in.
Tip #4:
You can use FYS even if you are double-heading with another engine
regardless of whether the second engine is equipped with an FYS programmed
Proto-Sound® module. If the second engine isn’t equipped with FYS, the only
thing to remember is not to turn up the transformer throttle very high when
entering Reverse in Stage 2. If the throttle is set too high, then the second
locomotive will begin vibrating on the track as its motors will be turning in
reverse. If your second engine is equipped with FYS, you may want to disable
the FYS when used in double-headed operations. To disable FYS, see the
section on programming RESET functions on page 22 of this manual.
Tip #5:
You can leave any of the event stages at any time by simply
interrupting the transformer throttle. Any sound effects programmed to play in
that event will simply not occur. The only exceptions are Event 1 and Event 4.
In Event 1, interrupting the throttle has no effect on FYS until after the man’s
whistle has completed and the freight car doors have opened. In Event 4, you
cannot interrupt FYS until after the engine begins to move. Interrupting the
throttle before the engine begins to move has no effect on the locomotive’s
operation.
