1. Product Overview
The SP CONNECT Universal Phone Clamp SPC+ is designed to securely hold your smartphone, allowing you to utilize your preferred phone case while still benefiting from the convenience of quick attachment and removal from various mounts. This clamp is compatible with all smartphones ranging from 2.3 to 3.3 inches (58 to 85 mm) in width. It features a screw adjustment system for precise width setting, which locks into place once the dial is pushed. The interior of the clamp is lined with rubber to prevent scratches on your smartphone and to ensure it remains stable without sliding.
Please note that a separate mount (for bicycle, car, or motorcycle) is required and must be purchased independently to use this product.

2. Setup and Installation
2.1 Adjusting the Clamp Width
- Locate the screw adjustment dial on the side of the Universal Phone Clamp.
- Rotate the dial to open the clamp jaws wider than your smartphone's width.
- Carefully place your smartphone into the clamp, ensuring it is centered.
- Rotate the dial in the opposite direction to tighten the clamp jaws until they firmly grip your smartphone. Ensure the phone is snug but not overly compressed.
- Once the desired width is achieved and the phone is secure, push the dial inwards to lock the adjustment. This prevents accidental loosening.

2.2 Attaching to a Mount (Mount Sold Separately)

- Align the SPC+ interface on the back of the Universal Phone Clamp with the corresponding receiver on your SP CONNECT mount.
- Insert the clamp into the mount and rotate it 90 degrees clockwise until you hear a distinct click. This indicates that the clamp is securely locked onto the mount.
- To remove, rotate the clamp 90 degrees counter-clockwise and pull it away from the mount.

4. Maintenance
To ensure the longevity and optimal performance of your SP CONNECT Universal Phone Clamp SPC+, follow these simple maintenance guidelines:
- Cleaning: Wipe the clamp regularly with a soft, damp cloth to remove dust and dirt. Avoid using abrasive cleaners or solvents, as these can damage the material.
- Inspection: Periodically inspect the clamp for any signs of wear, such as cracks in the plastic, damage to the rubber pads, or issues with the screw adjustment mechanism.
- Storage: When not in use, store the clamp in a clean, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
- Phone does not fit in the clamp:
Ensure your smartphone's width is within the compatible range of 2.3 to 3.3 inches (58 to 85 mm). If you are using a thick phone case, it might exceed the maximum width. Try removing the case or consider a thinner one. - Phone feels loose or slides:
Make sure the screw adjustment dial is tightened sufficiently and then pushed in to lock the setting. Verify that the internal rubber pads are intact and clean, providing adequate grip. - Clamp does not securely attach to the mount:
Ensure you are using an SP CONNECT mount with the SPC+ interface. Confirm that the clamp is fully inserted and rotated 90 degrees clockwise until a click is heard, indicating it is locked. Avoid forcing the attachment. - Difficulty removing the clamp from the mount:
Ensure you are rotating the clamp 90 degrees counter-clockwise before attempting to pull it off the mount. Do not twist or pull excessively without proper rotation.
