Passenger Station Announcements (PSA)
Your engine is equipped with a sound package of passenger statio n
announcements that you can play when you pull into a station. Each sequence
described below will play as long as it is left on, randomly generating sounds, but
be sure to allow approximately 30 seconds between the button pushes described
below to allow the PSA sufficient time to run through each sequence.
• To cue the sound system to play the PSA, quickly but firmly tap the Bell
button once followed by 2 quick taps of the Hor n button while the
engine is moving. Tap the buttons quickly but allow approximately ½
second between each press.
• Press the Direction button once to stop the engine. This will trigger the
first sequence of PSA. The reverse unit is temporarily disabled so that the
train will not move as you use the Direction button to trigger the sounds,
and Proto-Sound 2.0 has disabled operator control over the Horn and
Bell buttons until the full PSA sequence is complete.
• After waiting about 30 seconds for that sequence to run, press the
Direction button again to trigger the second sequence of PSA. •After
about 30 seconds, press the Direction button again to trigger the third
PSA sequence.
• Again, after allowing about 30 seconds for that sequence to run, press
the Direction button one more time to trigger the fourth and final PSA
sequence. The PSA will continue, and within a few seconds, the engine
will start and move out on its own at the current throttle setting, in the
same direction it was traveling when you began the sequence. Once the
bell turns off, the operator regains control of the transformer's Bell and
Horn buttons and can ring the bell or blow the horn as usual.
