2. Focusing and Magnification
Place the object you wish to observe on the base. Adjust the height of the microscope unit using the knob on the stand to bring the object into approximate focus. Then, fine-tune the focus by rotating the focus wheel on the lens barrel until the image on the screen is clear.

3. Magnification Lenses and Applications
- Lens 1000X (2X-1000X): Ideal for observing coins, stamps, and stones, providing a full view of an entire coin.
- Lens 1500X (10X-1500X): Suitable for intricate tasks such as PCB soldering and watch repair, offering a stable and spacious work area.
- Lens 2500X (2000X-2500X): Designed for biological slides and mite observation. Note: The observation distance for the 2500X lens is 3mm-4mm, requiring the lens to be very close to the object for focus.

Maintenance
- Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses to gently clean the microscope lenses. Avoid abrasive materials or harsh chemicals.
- Cleaning Screen: Wipe the IPS screen with a soft, dry microfiber cloth. For stubborn smudges, use a screen-cleaning solution applied to the cloth, not directly to the screen.
- General Cleaning: Keep the microscope body and stand free from dust and debris using a soft brush or cloth.
- Storage: Store the microscope in a dry, dust-free environment when not in use. Consider using a protective cover.
Troubleshooting
- No Power: Ensure the USB power cable is securely connected to both the microscope and a working power source. Check if the power button is pressed.
- Blurry Image: Adjust the microscope's height on the stand and rotate the focus wheel until the image is clear. Ensure the correct lens is selected for the observation distance. For the 2500X lens, the object must be very close (3-4mm).
- No Image on External Display: Verify that the HDMI or USB cable is correctly connected to both the microscope and the external display/computer. Ensure the external display is set to the correct input source (HDMI/USB).
- Remote Control Not Working: Check the battery in the remote control. Ensure there are no obstructions between the remote and the microscope's sensor.
- Cannot Record/Save: Confirm that the Micro SD card is properly inserted and has sufficient free space.
