1. Product Overview
The FITCAMX CPL (Circular Polarizing Lens) Filter is designed to reduce unwanted reflections and glare from non-metallic surfaces, such as your car's dashboard and windshield, when recording with your FITCAMX dash camera. This results in clearer, more vibrant video footage, especially in bright or sunny conditions, and improves the readability of details like license plates.

2. Installation Guide
2.1 Choosing the Correct Model
There are several types of FITCAMX CPL filters, each designed for specific dash camera models or vehicle types. To ensure compatibility, it is highly recommended to contact FITCAMX support with your vehicle model name and year before ordering.
- For FITCAMX Audi Model A, please choose CPL-7708.
- The CPL-9220 model is specifically designed for rear cameras only.
Note on CPL-3869 (Universal Model):
While CPL-3869 is a universal model, it may not be compatible with all FITCAMX cameras. Its size might also be slightly larger than the original lens, though this typically does not affect its polarization function. Always verify compatibility.



2.2 Attaching the CPL Filter
The CPL filter is designed for easy installation using 3M tape. Simply align the filter with your FITCAMX dash camera lens and securely attach it. Ensure the lens is clean before attachment for optimal performance.


3. Operating the CPL Filter
3.1 Adjusting the Polarization Angle
Once installed, you can manually rotate the CPL filter to adjust the polarization angle. This allows you to fine-tune the glare reduction based on lighting conditions and the angle of the sun.

3.2 Benefits of Proper Adjustment
Proper adjustment of the CPL filter significantly reduces reflections from your car's dashboard and windshield. This makes recorded video footage clearer and improves the visibility of important details, such as license plates, which can be crucial in accident reconstruction or evidence collection.

4. Maintenance
To ensure the longevity and optimal performance of your FITCAMX CPL Filter, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free microfiber cloth specifically designed for optics to gently wipe the filter surface. For stubborn smudges, lightly dampen the cloth with a lens cleaning solution (do not spray directly onto the filter).
- Avoid Abrasives: Never use abrasive materials, paper towels, or harsh chemical cleaners, as these can scratch or damage the filter coating.
- Storage: When not in use, store the CPL filter in a protective case or pouch to prevent dust accumulation and accidental damage.
5. Troubleshooting
If you encounter issues with your CPL filter, consider the following:
- Blurry or Unclear Image:
- Ensure the filter is clean and free of smudges or dust.
- Rotate the filter slowly while observing the dash camera's live view (if available) to find the optimal polarization angle.
- Filter Not Fitting Correctly:
- Verify that you have the correct CPL model for your specific FITCAMX dash camera and vehicle. Refer to Section 2.1 or contact FITCAMX support for compatibility confirmation.
- If using the CPL-3869 universal model, be aware that slight size differences may occur, but it should still function if compatible.
- Persistent Glare:
- Re-adjust the rotation angle of the filter.
- Ensure the filter is securely attached and not loose.
If problems persist, please contact FITCAMX customer support for further assistance.
