- Removing Your Phone: Press the release button or gently spread the side arms to release your phone.
- Adjusting View Angle: The ball joint allows for 360-degree rotation. Loosen the securing nut slightly, adjust your phone to the desired portrait or landscape orientation, and then re-tighten the nut to fix the position.
- Stability: The holder is designed to keep your phone steady even on bumpy roads, turns, and speed bumps, ensuring uninterrupted navigation or media playback.
5. Maintenance
To ensure the longevity and optimal performance of your phone holder, follow these simple maintenance guidelines:
- Cleaning: Wipe the holder and base periodically with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the material.
- Inspection: Regularly check the connections and moving parts for any signs of wear or looseness. Ensure the base remains securely attached to the dashboard.
- Avoid Over-tightening: When adjusting the ball joint, tighten only enough to secure the position. Over-tightening can cause unnecessary stress on the components.
6. Troubleshooting
If you encounter any issues with your Conpert Car Phone Holder, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Holder feels loose or wobbles. | Base not fully secured; ball joint nut loose. | Ensure the custom-fit base is firmly clipped into the dashboard slot. Tighten the securing nut on the ball joint. |
| Phone does not fit or is not held securely. | Phone size exceeds holder capacity; mechanical arms not fully engaged. | Verify your phone's dimensions are within the holder's adjustable range. Ensure the side arms fully close around your phone. |
| Difficulty adjusting viewing angle. | Ball joint securing nut is too tight. | Slightly loosen the securing nut on the ball joint, adjust the angle, then re-tighten. |
