Hi, I have an alarm sound going off part way through my second shift. Its a 1 second interval alarm and I don't know what it is. I went into audio to turn down various sounds and the alarm goes away when turning down 'Warnings...'. So its a warning sound. What could it be? Does the bus require gas or some other resource?
I've tried flicking all kinds of switches, opening and closing doors/hatches, kneeling, raising and lowering the bus etc.
