3. Press the SET button to open the selected submenu.
4. Use the left/right buttons to step through setting items within the submenu.
5. Press the SET button to confirm the selected setting item.
6. Press the Return button to go back to the previous interface and save settings.
7. Press the Return button again to exit to the main interface.

Key Menu Options:

• Markup: For adding visual markers to images.
• Image: Select image modes (Thermal, Visible, Fusion, PIP) and manage QR codes.
• Palette: Switch between different color display schemes.
• Measure: Access measurement tools like point, line, rectangle, and circle.
• System (⚙️): Configure device settings including Camera Model, Units, Parameters, HI/LO Alert, QR CODE, and Language.

6. Markup

This feature allows users to add markers, such as a center point, to the thermal image for analysis. Access the Markup menu via the main menu, select the desired marker type (e.g., "Center"), and press SET to apply or exit.

7. Image

Users can select different image modes: Thermal, Visible Light, Fusion, and Picture-in-Picture (PIP). The Fusion mode allows adjustment of the mix proportion and distance. The PIP mode enables repositioning and resizing of the picture-in-picture window. The QR function allows manual input or scanning of QR codes.

8. Palette

This function allows users to switch between various color palettes for displaying thermal images. Available palettes include Iron, Rainbow, Whitehot, Redhot, Blackhot, Lava, and Rain.HC.

9. Measure

The Measure function provides tools for temperature analysis, including Point, Line, Rectangle, and Circle measurements. Users can add, move, stretch, compare, and delete analysis objects. The display shows temperature information for selected objects. A "Save tool" option allows users to save custom measurement presets for later use. The device supports a maximum of 6 analysis objects (5 points, 1 line, 3 rectangles, 3 circles).

10. Isotherm

The Isotherm feature offers analysis options such as Auto, Ratio, Below, Above, Section, and Manual, aiding in the interpretation of temperature distributions across the image.
