a) Connect the ESC’s BEC wire to the programmer following the color orientation shown in the diagram above (Black ground wire aligns with the right edge). b) Power on the ESC and flip its power switch. For 80A and 120A ESC models, hold down the ESC button continuously during this step. c) If the green programming LED on the programmer flashes twice then stays solid on, the ESC and programmer are connected successfully. The LED will then turn off momentarily as the programmer reads the ESC’s current parameters and lights up the corresponding LED for each function item. If this does not happen, the connection has failed. d) Press the Down button on the programmer to switch between different programming items. The matching LED for the selected item will light up to indicate your current selection. e) Press the Right button on the programmer to cycle through adjustable values under the selected item; the LED for the chosen value will illuminate. f) Repeat steps d and e to configure all required parameters. g) Press the Program button on the programmer to write all adjusted settings to the ESC. The programming LED will light up during writing; it will turn off after more than 5 seconds to signal successful programming. If programming fails, power off the ESC and restart the whole process.

Press the Factory Reset button on the programmer to restore the ESC to its factory default settings. The programming LED will light up when the reset process starts. If it turns off after more than 5 seconds, the reset is successful. If not, the reset failed. Power off the ESC and perform the reset again.
