(12) Source Engaged Lamp: Lights up to show another OS knob (10) has already engaged the number you've selected. This might be an OS knob in another cubicle. Switch off. Do not send cue or clean feed.
This light was good because it stopped you making a mess of someone else's programme. And when it came on you usually did call the colleague who'd engaged the source elsewhere an OS knob, and occasionally something stronger.
