All of Battlefield Sports equipment can be activated with the turn of a key. This allows you to boot up all equiment in a matter of minutes. For simplicity, a single key fits all devices. 

Shutting down all equipment is just as easy. And there's even a function on the master controller to check if you've forgetten to switch off one of the devices. 

Switching off all the equiment can save battery lifetime while you're waiting for the next group to arrive, or while moving to another location.
