Using your Aervoe 1186-5 safety cones is easy. First, take the cones out of the storage case. Unfold them and place the 8-pound weighted rubber base at the bottom for stability. Insert the AAA batteries into the LED lights, then attach one light to the top of the cone and the other inside. Place the cones wherever you need to mark a hazard, like on the roadside or at a construction site. When you're done, turn off the LED lights, remove the batteries, collapse the cones flat, and store them back in the case. Keep the cones clean by wiping them with a damp cloth. Avoid exposing them to extreme heat or sharp objects that could damage the nylon material. If you have any issues, refer to the 1-year manufacturer's warranty.
