What are the serving timing rules in beach volleyball?

• The server must hit the ball within 5 seconds after the first referee whistles for service.
• A service executed before the referee's whistle is cancelled and repeated.
• If the serving team wins a rally it scores a point and keeps serving. If the receiving team wins the rally it scores a point and serves next.
