6. Operating Instructions
6.1 Starting the Software
Launch the Dino-Lite software application on your computer. The live image from the microscope should appear on your screen.
6.2 Adjusting Magnification and Focus
- Rotate the magnification dial on the microscope body to adjust the desired magnification level (10x to 330x).
