# What Do the Icons in the App Mean? (Red, Yellow, Green)

## Quick Diagnosis of Issues Based on Status Icons

**Camera Icon:**

- **Red:** Error. The sensor cannot access the camera. Try restarting the app and the sensor.
- **Green:** All ok. The cameras are ready.
- **Yellow:** Too little light. The system may switch to satellite data.

**GPS Icon:**

- **Red:** No signal. Check that you have a clear view of the sky. Wait 15 seconds for satellite connection.
- **Yellow:** Signal ok (approx. 5-meter accuracy). You can start work.
- **Green “R”:** RTK is active (cm-level accuracy). Requires internet connection.

**ISOBUS / Link Icon:**

- **Red:** No connection to the implement. Check the cables and that the UT (Universal Terminal) is displayed on the screen.
- **Not spraying?** Check if the “Setpoint Rate” in PerPlant UT (on the tractor screen) shows a value. If it is 0, the sprayer is not receiving instructions.
