volts or less and press and hold the whistle button for at least three seconds.

You will hear the bell turn on and, after three seconds, you should hear a

short horn blast or air release. Once the horn blast or air release is heard,

the whistle button can be released. The bell will continue to chime, so if

you want to turn off the bell ringing, simply press and release the whistle

button. Interrupt the transformer throttle to enter the next directional state

(either forward or reverse). (Note: the PFA will only play in the first

Neutral after it is armed. You can not interrupt the power twice to enter

another direction and still have the PFA active.) You can now trigger the

sounds to begin playing when you next enter Neutral.

Triggering Passenger Station Announcements

Once the PFA feature has been activated, it will be played the next time the

engine enters neutral. At this point,

Proto-Sound® will take over control of

your engine, disabling the bell and

whistle button. In addition,

Proto-Sound® reconfigures the way the

reverse unit functions during the

operation of the PFA feature. This

forces the engine to leave your

Passenger Station in the same direction as it arrived. The following

operator controlled “Events” control the PFA’s actions and sounds. (Note:

The direction states shown assume the PFA is entered from forward. If

entering the Passenger Station in reverse, the direction states shown will

be reversed.)

Event 1: Interrupt the transformer throttle

to cycle the engine from forward into

neutral. If the throttle was at 14 volts or

higher, the squeaking brakes sound will play.

Once the engine is stopped, the throttle must

be turned on to keep it in the neutral state.

Note: Failure to turn the throttle back on

within 3 seconds of leaving forward will

disable PFA and shutdown Proto-Sound®.

The next time power is turned on, the engine will be in the RESET

position. See page 19 for additional information on RESET. If the bell

was not turned off after arming PFA, it is now turned off automatically.

After entering neutral, Proto-Sound® will immediately play a horn blast or
