4. Operating Instructions
4.1 Power On/Off
Press the Power button on the microscope host or the wired light control remote to turn the device on or off.
4.2 Adjusting Focus and Magnification
Use the focusing wheel on the side of the microscope host to adjust the image clarity. The metal lifting bracket allows for vertical adjustment of the microscope, changing the working distance and thus the magnification. The focus range is typically between 5cm and 15cm.

4.6 Capturing Photos and Videos
Insert a compatible SD card (up to 32GB, not included) into the SD card slot. Use the Photo/Video button on the microscope host or the IR remote control to capture images or record video footage of your observations.
5. Maintenance
5.1 Cleaning
- Lens: Use a soft, lint-free cloth specifically designed for optical lenses. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth, not directly to the lens.
- Screen: Wipe the display screen with a soft, dry cloth. Avoid abrasive materials or harsh chemicals.
- Body: Clean the microscope body and stand with a slightly damp cloth. Ensure no liquid enters the electronic components.
5.2 Storage
When not in use, store the microscope in a clean, dry, and dust-free environment. Avoid extreme temperatures and direct sunlight. If storing for extended periods, remove any batteries from the IR remote control.
6. Troubleshooting
If you encounter issues with your Andonstar ADSM301 Digital Microscope, please refer to the following common problems and solutions:
- No Power: Ensure the power adapter is securely connected to both the microscope and a working electrical outlet. Check if the power button has been pressed.
- Blurry Image: Adjust the focusing wheel carefully. Also, ensure the working distance (height of the microscope from the object) is within the optimal range (5cm to 15cm) and adjust the lifting bracket if necessary.
- No Image on External Display (HDMI): Verify the HDMI cable is correctly connected to both the microscope's HDMI-OUT port and the external display's HDMI input. Ensure the external display is set to the correct HDMI source.
- No Image on PC (USB): Confirm the USB cable is properly connected. Ensure the correct driver is installed on your computer and that the measurement software recognizes the microscope as a USB camera.
- LED Lights Not Working: Check the connection of the wired light control remote. Ensure the power is on and try adjusting the brightness settings.
- IR Remote Not Responding: Check the battery in the IR remote control. Ensure there are no obstructions between the remote and the microscope's IR receiver.
If the problem persists after attempting these solutions, please contact customer support for further assistance.
