# Installing and Removing Your ROCK Ultra LiDAR System – Quick Start Guide

## Installing and removing the ROCK Ultra LiDAR unit is a straightforward process—but it’s important to follow the proper steps to ensure data accuracy and avoid damage to sensitive hardware.

The lever arm and GNSS rod & antenna are unique to the ROCK Ultra.  A lever arm or GNSS rod & antenna from other ROCK LiDAR units cannot be used with the ROCK Ultra unit.  

Follow these steps in order to set up your ROCK Ultra for flight:

1. **Install Lever Arm on Skyport**
   
     - Remove the protective cap from the lever arm and store it safely.
     - Align the **white and red dots**, then **turn counterclockwise** until the lever arm clicks into place (the red dots will be aligned).
2. **Attach GNSS Rod and Antenna**
   
     - Insert the GNSS rod vertically into the lever arm connection point.
     - Rotate the threads until hand-tightened and secure.
3. **Mount the ROCK Ultra Unit**
   
     - Carefully install the ROCK Ultra onto the lever arm. The camera will be facing forward (direction of flight).
     - **Do not touch the laser cover** on the bottom of the unit during handling.
4. **Insert the USB Drive**
   
     - Use a compatible USB drive. Learn more about [USB drive specs](https://learn.rockrobotic.com/what-flash-drive-works-with-the-r3-pro?hsLang=en) if needed.
5. **Power On the Unit**
   
     - Hold the **large side button** for several seconds until a red light appears.
     - The LED will turn **green** after the self-check and GNSS initialization.

### 🧰 Removal Steps

Reverse the installation steps when you're done collecting data:

- Power off the unit.
- Detach the ROCK Ultra from the lever arm, and put back in the case.
- Unscrew and remove the GNSS rod vertically.
- Press the release button on the lever arm, rotate **clockwise** to align the red and white dots, and remove the lever arm.
- Reapply the protective cap and store all components securely.

By following this setup, you'll ensure accurate data capture and safe handling of your ROCK Ultra system.
