How do I use the Hot Key to copy settings from one controller to another?

To upload settings to the Hot Key, turn the controller ON, insert the Hot Key, press the down arrow key until 'uP' appears followed by a flashing 'Ed', then press SET to confirm. To download to another controller, turn it OFF, insert the programmed Hot Key, then turn it ON — the parameters will automatically load and the controller restarts after 10 seconds. An 'Er' message indicates a failed transfer. (Page 2)
