Activating Proto-Sound 3.0 Conventional AC Mode Features
Using an AC output transformer equipped with a whistle and bell button will unlock
dozens of features inside your RailKing One-Gauge locomotive. Operation is simple by
following the simple steps below and on the following pages.
Start Up
: Turn the throttle knob up ½-way, until the engine headlight shines bright. Put
the engine into motion by pressing the Direction button on your transformer once.
(hold it for approximately 1 second)
If the engine does not begin to move as soon as you firmly press the Direction button,
you may not have sent enough voltage to the track to make the train move. Turn the
throttle up a bit higher until the train begins to move.
Throttle
: To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while turning
counterclockwise will decrease voltage and speed. The engine will maintain the speed
you set after you release the throttle until you turn it again to change the voltage and
speed.
Bell:
To sound the bell, in an engine equipped with a bell firmly press and release the
Bell button. To turn the bell off, press and release the Bell button again. The bell will
continue to ring from the time you turn it on until you press and release the button
again to turn it off.
Horn/Whistle
: To sound the whistle, firmly press the Horn/Whistle button. The
whistle will sound for as long as you continue to depress the button. It will stop when
you release the button.
Direction:
Your train is programmed to start in neutral. The train will always cycle
neutral-forward-neutral-reverse with each press and release of the direction button.
The engine is programmed to restart in neutral each time the track voltage is turned off
for 25 seconds or more.
