4. Operating Instructions
4.1. Power On/Off
Locate the power button on the microscope unit. Press and hold for a few seconds to power on or off the device. The 10.1-inch IPS screen will illuminate upon startup.
4.2. Focus Adjustment
- For Stand-Mounted Use: Rotate the focus wheel on the microscope body until the image on the screen is clear and sharp.
- For JL115A Handheld Use: Utilize the built-in distance adjustment ring on the JL115A to reduce hand shake and achieve a clearer view. Rotating the ring increases the working distance and expands the field of view.
4.3. Magnification
Magnification is primarily adjusted by changing the working distance between the microscope lens and the object. Moving the microscope closer to the object increases magnification, while moving it further away decreases it. Fine-tune focus after each adjustment.
4.4. Lighting Control
The microscope is equipped with multiple lighting options to ensure optimal illumination for various specimens:
- Built-in LED Lights: These are typically located around the lens. Use the dedicated buttons or controls on the microscope to adjust their brightness.
- Side LED Lights: The standard metal stand includes adjustable side LED lights. Position them to eliminate shadows and provide even illumination.
- Bottom Light Stage: For transparent or translucent specimens (e.g., biological slides), place them on the bottom light stage. Activate the bottom light for transmitted illumination.

4.5. Recording and Capturing Images
The JL210 features 1080P HD video recording and a 12MP camera sensor for high-quality image capture.
- Photo Button: Press the designated photo button to capture still images.
- Record Button: Press the record button once to start video recording and again to stop.
- Storage: Captured photos and videos are saved to an inserted memory card (not included, typically microSD).
4.6. Connecting to a PC
