Setup and Installation
Follow these steps to properly install your Celly Car Holder Flex Plus in your vehicle.
- Choose a Mounting Location: Select a clean, flat surface on your dashboard or windshield. Ensure the chosen location does not obstruct your view of the road or interfere with airbags or vehicle controls.
- Clean the Surface: Thoroughly clean the chosen mounting surface with a suitable cleaner and allow it to dry completely. This ensures maximum suction cup adhesion.
- Attach the Suction Cup: Press the suction cup firmly against the cleaned surface. Engage the locking mechanism (if present) on the suction cup base to create a strong vacuum seal.
- Adjust the Flexible Arm: Position the flexible arm to your desired viewing angle. The 14 cm flexible arm allows for significant adjustment.
- Orient the Phone Cradle: Rotate the phone cradle 360° to achieve either portrait or landscape orientation, as preferred.

Maintenance
To ensure the longevity and proper functioning of your Celly Car Holder Flex Plus, follow these simple maintenance guidelines:
- Cleaning: Regularly wipe the holder and suction cup with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the materials.
- Suction Cup Care: If the suction cup loses its grip, clean both the cup and the mounting surface thoroughly. A small amount of moisture on the suction cup can sometimes help restore adhesion.
- Storage: When not in use for extended periods, store the holder in a cool, dry place away from direct sunlight and extreme temperatures.

If you encounter issues with your Celly Car Holder Flex Plus, refer to the following common problems and solutions:
- Problem: The suction cup does not adhere securely to the dashboard or windshield.
