NevadaRef:

Team A has the Ball for a Stopped-Clock Designated Spot Throw-in. A1 releases the Ball on a pass that crosses the Boundary Line at the Throw-in's Designated Spot. The Ball crosses another Boundary Line and goes Out-of-Bounds while never being touched by any other Player. Team A has committed a Throw-in Violation and by Rule, the Clock should not have started, but was started in error by the Timer. The Clock starting in error does not negate the Throw-in Violation by Team A. Penalize Team A for committing a Throw-in Violation by awarding Team B a Designated Spot Throw-in at the Spot of Team A's Throw-in and reset the Clock to 0.7 seconds.

The Ball becoming Dead when the Period ending Horn sounds only applies if the Clock was started correctly, and in the Play being discussed, the Clock should have never started.
