F4 – PFA
.
PFA in MTH lingo stands for Passenger/Freight Announcements. Your engine is
preprogrammed for the appropriate type of sounds based upon the type of service the
real-life engine used in daily operation. There are five sound sequences or segments in
the PFA feature. Each segment is advanced by you, the operator. You hit the F4 button
twice on the DCC controller to let the engine know you want it to advance (this toggles
the PFA function on then off to clear the remote for the next sequence). In most PFA
sequences there is a minimum wait time of about 20-30 seconds before it will advance.
So, here is how a typical PFA sequence operates:
1. Press the F4 button twice (toggle F4 on then off) to start the PFA sequence on the
engine. You’ll hear “Now arriving…” for passenger sound sets and cab chatter for
freight sound sets. The bell will then begin ringing.
2. Slowly reduce the throttle until the train stops at the desired location and speed reaches
zero. Press the F4 button twice (toggle F4 on then off) again and the bell will stop
ringing. You will hear the engine sounds switch from the cab to the station or yard with
all the ambient sounds you’d hear in the real thing.
3. Press the F4 button twice (toggle F4 on then off) again to advance the sequence. You’ll
hear “Now boarding…” for passenger sound sets and freight yard sounds for freight
sound sets.
4. Press the F4 button twice (toggle F4 on then off) again to advance the sequence. You’ll
hear “Now departing…” for passenger sound sets and more freight yard sounds for
freight sound sets.
5. Press the F4 button twice (toggle F4 on then off) the last time to advance the sequence.
You’ll hear “All aboard…” for passenger sound sets and more freight yard sounds for
freight sound sets. The engine sounds will switch over to the cab again. When the bell
begins to ring, advance the throttle to move the engine out of the station or yard. The bell
will shut off automatically.
