### Guide to operating the RadioMaster Zorro

#### **1. Power On the Controller**

* Turn on the Radiomaster Zorro using the power switch.
* Wait until the main screen appears.

***

#### **2. Connect to the Computer**

* Locate the **USB-C connector** under the display, between the **S1** and **S2** sliders.
* Use a USB-C cable to connect the controller to your computer.
* Make sure the cable supports data transfer (not just charging).

***

#### **3. Handle the Throttle Warning**

* When connected, the Zorro will display a **"THROTTLE WARNING"** message.
* Press any key to continue.
* The controller may prompt you to **set all sticks, sliders, and switches to their default (neutral) positions** — follow the on-screen instructions.

***

#### **4. Select USB Mode**

* After calibration prompts, a **USB mode selection** window will appear on the Zorro’s screen.
* Choose the **first option**: **`USB Joystick (HID)`**
* Confirm your selection.

***

#### **5. Ready to Use**

* The Zorro is now configured as a USB joystick and will be detected by your computer as a controller (HID device).
* You can proceed to the **Nexus** application to configure button mappings and joystick controls.
* Go to ***Gear Icon*** on the left down corner and after that click on the ***Go to controller settings***
* Press the **pen** icon to enter edit mode.
* Press the physical button or move stick on your Zorro that you want to assign.
* The Nexus app will automatically map that function to the button.
* Repeat for all buttons you want to configure.
