Performing factory reset at the device
To perform the reset enter SETUP MENU. Release the button once and push and hold it again. Keep the button pressed for at least 15 seconds. You will see the Menu LEDs cycling down from A to N. This shows factory reset was performed. The system will exit SETUP MENU when you release the button. Now all settings are set to default and you have to perform the Basic Setup again in order to fly the helicopter.
