OK
I'm a little confused
Does the Voice Alert not indicate you are being targeted? Or do you need to hear the buzzer?
Also, when does the auto-off count down start?
At the beginning of the voice alert or the buzzer?

The voice alert/siren indicates you're being targeted. If you're in Pro mode and are still being targeted after the voice alert finishes, then you'll hear the buzz, but hopefully you've JTKed before then.

The auto-off count down starts at the beginning of the alert. Remember, you'll start hearing noise of some sort (beeps from regular control set or sirens from the hi-fi) as soon as the ALP starts seeing pulses from the gun and has started jamming. So that's when you need to react. When the speaker squawks, it's time to act!
