70mai CPL Filter II Instruction Manual

1. Introduction

The 70mai CPL (Circular Polarizing Lens) Filter II is an essential accessory designed to enhance the video quality of your compatible 70mai Dash Cam. It effectively reduces unwanted reflections and glare from surfaces like your windshield and road, while also boosting color saturation for more vibrant and detailed footage. Additionally, the filter provides an extra layer of protection for your dash cam's lens against fingerprints, scratches, and dirt.

This CPL Filter is specifically designed for use with 70mai Dash Cam A810, A810S, Omni X800, and T800 models.

Important Note: Tinting film on your front windshield may impact the functionality and effectiveness of CPL filters.

2. Setup and Installation

Follow these steps to correctly install the CPL Filter onto your 70mai Dash Cam:

1. Identify the correct CPL filter for your specific dash cam model (A810/A810S, Omni X800, or T800). Each filter is designed to fit its respective dash cam lens precisely.
2. Gently align the CPL filter with the lens of your dash cam. Ensure the filter is oriented correctly, with the polarizing element facing outwards.
3. Carefully attach the filter to the dash cam lens. For models like the A810/A810S and Omni X800, the filter typically slides or clips onto the lens housing. For the T800, it may screw on. Ensure it is securely fastened but do not overtighten.
4. Once attached, you can rotate the outer ring of the CPL filter to adjust the polarization effect. This adjustment is crucial for optimizing glare reduction and color saturation.

3. Operating Instructions

The CPL filter works by selectively blocking polarized light, which is often the cause of glare and reflections. To achieve the best results:

• Adjusting the Polarization: After installation, rotate the outer ring of the CPL filter while observing your dash cam's live view or recorded footage. You will notice changes in reflections and color saturation. Rotate until you achieve the desired effect, typically when reflections are minimized and colors appear most vibrant.
• Reducing Reflections and Glares: The filter is highly effective in reducing surface reflections on your windshield and intense sun glares, allowing for clearer footage, especially in bright conditions.
• Enhancing Color Saturation: The CPL filter helps prevent colors from appearing washed out by strong light, maintaining appropriate contrast and leading to more vibrant and detailed images.

4. Maintenance

Proper care of your CPL filter will ensure its longevity and optimal performance:

• Cleaning: Use a soft, lint-free microfiber cloth specifically designed for camera lenses to clean the filter. For stubborn smudges or fingerprints, apply a small amount of lens cleaning solution to the cloth (not directly to the filter) and gently wipe.
• Protection: The CPL filter also serves as a protective layer for your dash cam's primary lens. Keep it installed to shield against dust, fingerprints, scratches, and minor impacts.
• Storage: When not in use, store the filter in a clean, dry place, preferably in its original packaging or a dedicated filter pouch to prevent damage.

5. Troubleshooting

• Suboptimal Glare Reduction/Color Enhancement:

  Ensure the CPL filter is correctly installed and securely attached. Rotate the outer ring of the filter slowly while observing the dash cam's display to find the optimal polarization angle. The effect is most noticeable when light sources are at a 90-degree angle to the filter.

• Impact from Windshield Tinting Film:

  If your vehicle's front windshield has tinting film, it may already have polarizing properties. This can interfere with the CPL filter's effectiveness, potentially leading to unexpected visual effects or reduced performance. There is no direct solution for this other than being aware of the interaction.

• Unclear or Blurry Footage:

  Check if the CPL filter is clean. Dust, smudges, or fingerprints can degrade image quality. Refer to the Maintenance section for cleaning instructions. Also, ensure the filter is not loose or misaligned on the dash cam lens.

7. User Tips

• Check Compatibility Carefully: Always verify that the CPL filter is compatible with your specific 70mai Dash Cam model. This CPL Filter II is designed for A810, A810S, Omni X800, and T800. It is NOT compatible with models like the 70mai A800.
• Optimal Rotation: Don't just attach the filter; take the time to rotate it while viewing your dash cam's screen to find the sweet spot for glare reduction and color enhancement. The effect can be subtle but significant.
• Consider Your Windshield: Be aware that aftermarket tinting on your windshield might already have polarizing properties, which could interact with the CPL filter. Experiment with rotation to see if you can still achieve a beneficial effect.
