You can use the pitching machine with or without a remote control, which controls the automatic ball feeder only - NOT the pitching machine. It is a simple on/off switch. Turn it ON, and the balls are released from the automatic ball feeder into the pitching machine approximately every 6 seconds. Turn it OFF, and the balls stop rolling into the pitching machine from the automatic ball feeder.
