2. P, G, R, T If you enter the incorrect keycode three times in a row on the AUS-211 audio unit, how long will it be locked up for before you can enter the keycode again?

The AUS-211 audio unit will be locked up for 30 minutes before you can enter the keycode again.

This context does not mention anything about how long the AUS-211 audio unit will be locked for after entering the incorrect keycode three times in a row, so I cannot answer this question from the provided context.
