in-game signals between officials

[chseagle]

Cobra, what I am meaning is that (at least around here) it's the signal from the timer that gets the floor officials attention if there is an error/discrepancy.

I have never tampered with the Auto Horn button, unless I noticed it is off (which has never happened).

What happens if the visual scoreboard malfunctions & in order to keep time a stopwatch has to be used?

It's the scorers' table that usually alerts the coaches & floor officials of a player's 5th foul & periodically 7/10 team fouls.

Depending on the gym design, it's the scorers' table that alerts the floor officials of shot clock violations (for those that have shot clock).

During varsity games, the PA Announcer usually announces 1 minute remaining in the period/game.
