The instructions I have for a Locosound direction lock are a little different.
Put the engine into the direction you want ,run it at a very slow crawl (as slowly as it will move without halting), and quickly but firmly tap the Horn button once followed by three quick taps of the Bell button, allowing approximately ½ second to lapse between each quick button press.
The engine will not change direction (including going into neutral) until you repeat the 1horn, 3bells code to return the engine to its normal condition, even if the engine is kept without power for extended periods of time.
