Using these shock - absorbing components is easy. First, securely place the DJI O4 Air Unit into the bracket. Then, attach the unit to the bracket with the four shock - absorbing balls, making sure everything is well - aligned and stable. When using, keep in mind that these components are designed for specific compatible cameras and quads, like the DJI O4 Camera, Meteor65 Pro O4, etc. Don't try to use them with incompatible devices. For maintenance, simply keep them clean. You can use a dry cloth to wipe off any dust. Store them in a dry place when not in use to maintain their performance.
