the air lines coming apart. It can best be described as a CHA-CHUSHHH
sound. The coupler doesn't have to be fired in NEUTRAL. Once the
coupler is armed it can be fired in Forward, Neutral or Reverse. However,
you may find that the coupler
doesn't open when firing the
coupler at high speeds. Reduce
the voltage setting on your
transformer if this occurs and
run your engine at a slower
speed before firing the coupler.
If the coupler continues to open
erratically, try lubricating the
knuckle with light oil as
indicated in Fig. 5.
ENHANCED
NEUTRAL STEAM SOUNDS
The enhanced Neutral Sounds can be automatically heard whenever the
engine is in neutral. The sounds, which include Steam Pop-Off, Steam
Blow-Down, and Steam Injector sounds occur every 2 to 30 seconds. Each
of the three sequences will play at random intervals to eliminate repetitive
and boring sequences. While the sounds are selected to play randomly by
the microprocessor, there is no guarantee that you won't hear the same
sound repeated twice or more times.
SQUEAKING BRAKE SOUNDS
ProtoSound® equipped engines feature the ability to play the sound of
squeaking brakes whenever your engine slows in speed. There are two
settings for activating the squeaking brake sounds. The default setting
allows the brake sounds to play while the engine is in forward or reverse
and the transformer throttle is lowered from a high setting to a low setting
(14 volts to 8 volts or less). The other setting requires that a bell button be
used to "arm" the brake feature and is explained in more detail in the
"Activating Passenger Sounds"
section found later in this
manual. The sound itself is a
stored record on the
ProtoSounds® software chip and
will always play the same brake
