## Detailed Instructions

### Assemble Aircraft

Assembly the aircraft per manufacturer instructions.&#x20;

### Attach 6X & Light Sensor/GPS

1. Attach 6X to the aircraft.&#x20;
2. Attach the light sensor/GPS to the aircraft.&#x20;
3. Connect the light sensor/GPS to the 6X using the provided USB-C to USB-C cable.
4. Secure the USB-C to USB-C cable to the aircraft. &#x20;

### Power Aircraft & Wait For Session Start

1. Power the aircraft on.&#x20;
2. Let the 6X boot (solid status red LEDs).
3. Verify the 6X has started a session (solid green status LEDs). This take about 1 minute and requires a GPS fix.&#x20;

### Verify Camera Settings

1. Connect USB-C cable to the USB-C port on the 6X.&#x20;
2. Connect the other end of the cable to a laptop.&#x20;
3. Open the webpage user interface.&#x20;
4. Select Configuration.
5. Under Trigger verify the overlap is set to the desired percentage.&#x20;
6. Unplug the USB-C cable from the 6X.&#x20;

### Verify Flight Settings

Verify the camera model/parameters, flight speed, survey altitude, and overlap settings.

The side overlap setting in the flight planning app should match the overlap setting on the 6X. This ensures the aircraft will fly with the appropriate spacing between transects that the 6X is expecting.&#x20;

### Capture Calibration Images (Optional)

1. Place the reflectance panel on a flat surface in direct sunlight.&#x20;
2. Pick up the aircraft and hold it waist high with the 6X directly over the reflectance panel.&#x20;
3. Press the button on the light sensor to start the calibration image capture.&#x20;
4. Hold the aircraft over the panel until the image capture is complete.&#x20;
5. Set down aircraft and pick up panel.&#x20;
