RailKing Dash-8 Operating Manual
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. 3.
For multiple heading purposes,
only one of the two
ProtoCouplers™ will function
at any one time. Use the
coupler direction switch as
shown in Fig. 5 on page 16 to
select either the front or rear
coupler. Simply slide the
switch toward the direction of the coupler you want to make active.
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 second setting requires that a bell button be
used to “arm” the brake feature and is explained in more detail in the
“Activating Freight Yard 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
