The panel's seatpost mounting clip is made using 3D printing technology. To attach the panel, gently press the red button and slide it into place. You'll hear a slight "click" when it clicks into place. The panel won't release automatically until the button is pressed. All metal components are made of stainless steel. If it becomes dirty, rinse thoroughly with cold or lukewarm water. The V2 version adds additional places to attach the panel to the clip using a cord or string. The clip also has a cutout for the antenna. The entire assembly has been improved for a more secure fit. On the Deus 2, mounting the panel may require more force initially. The set includes screws for mounting to the seatpost. It fits the Deus 1, Deus 2, and ORX. After using the clip in saltwater, rinse it with lukewarm tap water and blow it out thoroughly to prevent water from accumulating on the springs responsible for button operation.
