Tournament manager

in tournament manager i can change time for match. for example,i change from 60sec to 120 sec. But sound signal to switch controller is the same -25-35 sec. Can i change sound signal time? and where?

No, if you are running a VEX IQ game (Ringmaster, Crossover, etc.) the sounds will always happen at :35 and :25 per the game rules. This is not configurable.
