4. Operating Instructions
4.1 Lens Selection and Usage
The AD246SM-Plus comes with three interchangeable lenses, each designed for specific observation distances and magnification ranges:
- Lens A (18X-720X): Ideal for observing larger objects such as coins, stamps, circuit boards, and stones. Observation distance: 12mm-320mm.
- Lens L (60X-240X): Suitable for PCB/SMD soldering and general circuit board observation. Observation distance: 90mm-300mm.
- Lens D (1800X-2040X): Designed for microscopic slides and very fine details. Observation distance: 4mm-5mm.
To change a lens, gently twist the current lens counter-clockwise to remove it, then align the new lens and twist clockwise until secure.

4.2 Focusing and Magnification Adjustment
Use the focus knob on the microscope body to achieve a clear image. Adjust the distance between the lens and the object by moving the microscope unit up or down on the stand for optimal magnification and clarity.

4.3 LED Lighting and Remote Control
The built-in 8 LED lights provide adjustable brightness and lighting angles. Use the remote control to capture images and record videos without disturbing the microscope, ensuring stable and clear results.
5. Maintenance
- Cleaning Lenses: Use a soft, lint-free cloth and lens cleaning solution to clean the lenses. Avoid abrasive materials.
- General Cleaning: Wipe the microscope body and stand with a dry or slightly damp cloth. Do not use harsh chemicals.
- Storage: Store the microscope in a dry, dust-free environment when not in use.
- Soldering Mat: The silicone soldering mat is resistant to heat, dirt, and oil. Clean it regularly to maintain its protective properties.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on screen | Power not connected; Microscope not turned on; HDMI/USB cable loose or faulty. | Check power connection; Press power button; Reconnect or replace cables. |
| Blurry image | Incorrect focus; Wrong lens for object distance; Object too far/close. | Adjust focus knob; Select appropriate lens (A, L, or D); Adjust microscope height. |
| Screen flickering or unstable image | Loose cable connection; Power supply issue; Interference. | Ensure all cables are securely connected; Try a different power outlet; Minimize electronic interference. |
| Remote control not working | Batteries depleted; Obstruction between remote and microscope. | Replace remote control batteries; Ensure clear line of sight to the microscope's IR receiver. |
