Using this playset is super easy! First, put the 6x LL44 batteries that come with the set into the car and the police pick - up. Once the batteries are in, turn on the power switch to make the car light up, change colors, and play those cool sounds. For the Police Helicopter, you can manually rotate the propeller blades to create the effect of flight. When your little one is done playing, turn off the power to save battery life. Keep the playset away from water and rough play to avoid damage. If the sounds or lights seem weak, it might be time to replace the batteries. This playset is designed for kids aged 3 and up, so make sure to supervise younger children during play to ensure safety.
