4. Operating Instructions
4.1 Understanding the Controls
The device features several switches and potentiometers to fine-tune the scanline effect. Refer to the diagram and table below for a description of each control.
| Switch/Potentiometer | Function |
|---|---|
| A (ON/OFF) | Master switch for the scan line effect. Toggles the effect on or off. |
| B (RGB) | Three potentiometers for debugging and adjusting red, green, and blue tricolor components. Use a small screwdriver to adjust. |
| C (WIDTH) | Adjusts the width of the scan lines (double or single scan line effect). |
| D (VSYNC) | Resolution adapter switch. May be required to change resolution for optimal effect. |
| E (EVEN/ODD) | Toggles between odd or even scan line patterns. |
4.2 Adjusting Scanline Effects
Once connected, power on your video source and display. The scanline generator will automatically apply the effect. Use the switches and potentiometers to customize the appearance:
- Toggle switch A to enable or disable the scanline effect.
- Experiment with switch C (WIDTH) to choose between a subtle or more pronounced scanline appearance.
- If the image appears distorted or incorrect, try adjusting switch D (VSYNC).
- Switch E (EVEN/ODD) can alter the pattern of the scanlines, which might be useful for specific game types or preferences.
- The B (RGB) potentiometers are for advanced color calibration. Adjust these carefully with a small screwdriver if you notice color imbalances.
5. Maintenance
The Walfront Scanner Line Generator requires minimal maintenance. To ensure longevity and optimal performance:
- Keep the device in a dry, dust-free environment.
- Clean the exterior with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.

- Handle the switches and ports gently to prevent damage.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No scanline effect / Device not working | Loose VGA connections; Switch A (ON/OFF) is off; Incompatible resolution; Finicky switches. | Ensure all VGA cables are securely connected. Toggle switch A to the ON position. Try adjusting switch D (VSYNC). Gently jiggle or firmly press the switches to ensure they engage properly. |
| Image distortion or incorrect colors | Incorrect RGB calibration; Resolution mismatch. | Adjust the B (RGB) potentiometers slightly with a small screwdriver. Try adjusting switch D (VSYNC). Ensure your display is set to a compatible resolution. |
| Scanlines appear too thick or too thin | WIDTH switch setting. | Toggle switch C (WIDTH) to change between double or single scanline effects. |
| Scanlines are not uniform or appear odd | EVEN/ODD switch setting. | Toggle switch E (EVEN/ODD) to alternate the scanline pattern. |
