3.3. Initial Configuration

Upon first power-on or after a factory reset, you may need to configure basic settings:

1. Language Selection: Navigate to the "Settings" menu and select your preferred language.
2. Time and Date: Set the correct time zone, date, and time for accurate data logging.
3. Unit Settings: Choose your desired units for area (e.g., acres, hectares, square meters), distance (e.g., meters, feet), and slope (e.g., degrees, percentage).

4. Operation Guide

4.1. General Interface and Navigation

The device features a main interface with various icons and information. Use the directional buttons (Up, Down, Left, Right) and the Enter button to navigate through menus and confirm selections. The Back or Return button allows you to go back to the previous screen.

4.2. Area Measurement (Normal Area)

This mode is used for measuring irregular land areas by walking the perimeter.

1. At the starting point of the area to be measured, press the Start button on the main interface to begin the measurement.
2. Walk along the perimeter of the area. The device will track your path.
3. To pause the measurement, press the Stop button. You can then return to the starting point in a circle around the ground to resume or view the measurement data.
4. Once the measurement is complete (you have returned to the starting point or covered the entire perimeter), press the Power button to end the measurement and save the data.

4.3. Slope Measurement

The device can measure slopes from 0-90 degrees.

1. In the parameter settings, press the Up or Down button to set the gradient value if needed.
2. After setting, press the Power button to return to the main interface.
3. In the main interface, use the Up or Down button to switch the function to "Slope measurement".
4. Press the Start button at the starting point of the slope and circle the slope.
5. To pause measurement, press the Stop button. You can return to the starting point to resume measurement by pressing Start again, or view data.
6. Once the measurement is complete, press the Power button to save the data.
