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. 4.
For multiple heading purposes,
only one of the two
Proto-Couplers will function at
any one time. Use the coupler
direction switch as shown in
Fig. 1b on page 3 to select
either the front or rear coupler.
Simply slide the switch toward
the direction of the coupler you
want to make active.
NEUTRAL-ACTIVATED CAB CHATTER SOUNDS
Whenever your diesel locomotive is parked in Neutral, randomly played
“Cab Chatter” sound effects will occur every 2 to 30 seconds. There are a
total of four of these Cab Chatter sequences that capture authentic radio
transmissions between dispatcher and engineer. They are designed to play
at random intervals to eliminate repetitive and boring sequences though
there is no guarantee that you won’t hear the same message repeated two 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 sound itself is a stored recording on the
Proto-Sound® 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
oil coupler
