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
Proto-Sound® 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 sound for the same three second length each
time the voltage is reduced from
high to low. Some practice may
be required to synchronize the
playing of the brake sounds with
the movement of the engine. It
is not uncommon for the engine
