When attaching the camera to bicycles, scooters or skateboards, use the provided mounts to secure it firmly. Remember, the microSD card is not included, so you'll need to buy one if you want extra storage. As for maintenance, keep the camera clean by wiping it with a soft, dry cloth. Avoid exposing it to extreme temperatures or moisture outside of the waterproof case. Also, charge the built - in battery regularly to keep it working properly.
