I assumed that it wouldn't be doing anything.

It was turned on in absence of polarity reversal. It's actually been okay. I tuned the busy_min and busy_max values for tone and pause duration in the source code. Default was 75ms and 1100ms I think. Australian tone is 375ms, so I set it to 300ms and 450ms.
