F2 – Whistle
Blows the whistle for as long as it's on. There are several different ending signatures
depending on how long you hold the button down. Check it out!

Smoking Whistle

Since there is no playable whistle feature available in DCC, you enable the
smoking whistle by activating F7. When F7 is active, the smoking whistle
feature is now active and you can get smoke out of the whistle detail by hitting
F2 (regular whistle). It will also emit smoke for the whistle endings, Crossing
Signal, fwd and rev signals, and single toot. For additional information, see the
Smoking Whistle section at the beginning of this manual.
F4 – PFA
PFA in MTH lingo stands for passenger and freight announcements. Since your
engine provides freight service, you'll hear freight yard sounds. PFA is a very
popular sound feature that's a staple in almost all MTH products.
There are 4 sound sequences or segments in PFA. You advance through them at
your command. Each segment has a minimum time of ~10 seconds but more
sounds play the longer you listen.
When running the engine, simply press the F4 key to activate PFA. When you bring
the engine to a stop, the arrival sequence will play. You can remain in this segment
as long as you like.
Press F4 again, and advance to disembarking sequence. Again, you can listen to
this sequence as long as you like.
Press F4 again, and advance to the embarking sequence. Again, you can listen to
this sequence as long as you like.
Press F4 again, and advance to the departure sequence. After the engineer says
"Just keep the steam up" and the engine will automatically pull out and resume the
speed and direction of when you entered the feature. The bell ring for a short
while and then turn off automatically.
Lighting
As with other feature categories, lighting in DCC mode operates just like
conventional DC with regard to rule 17, constant brightness and directional
behavior. See that section for details. DCC provides some additional control to suit
your preferences.
F0 – Headlight
Toggles the headlight on/off.
F5 – Lights
Toggles all lighting (except the head & tail light) on/off, including Marker LED's.
When on, all lighting behaves automatically as described elsewhere. When F5 is off,
all lighting is off.
