How to use

Open the zip closure and place the mobile phone or smartphone inside the case, positioning it so that the screen is visible through any transparent panel or opening if present. Close the zip to secure the device. Attach the clamp mount to a suitable tubular bar, handlebar or mounting point, ensuring the clamp is tightened and the case is oriented for comfortable viewing. Remove the internal wallet when you need to access cards or documents separately. The design permits access to basic screen functions through the case while mounted, and the sun visor can be positioned to reduce direct sunlight on the screen.

Usage recommendations

For best results, check that the clamp is firmly secured before riding and avoid exposing the case to prolonged submersion; the weather-resistant construction protects against rain and splashes but is not intended as a full underwater housing. Remove the internal wallet when carrying multiple cards to minimize pressure on the zip, and periodically inspect the zip and mount for wear to maintain secure attachment.
