How do I program settings using the HOTKEY?

To upload settings from the controller to a HOTKEY: insert the HOTKEY, press the up arrow key until 'uP' appears followed by flashing 'Ed', then press SET. To download settings from a HOTKEY to the controller: turn OFF the instrument, insert the programmed HOTKEY, then turn it ON; the parameters will automatically download and the instrument will restart with the new settings after 10 seconds.
