1. If the tempo or quality of the music is deficient, the Competitor/s may restart the program from its beginning, provided the Referee is informed within 30 seconds after the start of the program.
2. If an interruption or stop in the music or any other adverse condition unrelated to the Competitor/s or his/their equipment, such as lighting, ice-condition etc. occurs, the Competitor/s must stop skating at the acoustic signal of the Referee. The Competitor/s shall continue from the point of interruption immediately after the problem has been solved.
