Using this Maisto Tech RC car is super easy. First, make sure to insert two AAA batteries into the pistol - shaped controller and charge the built - in lithium battery of the car using the included USB cable for about 45 minutes. Once charged, turn on the controller and the car. You can now control the car within a range of 115 ft. (35 meters). Up to 4 players can join in the fun simultaneously. When not in use, keep the car and controller in a dry and cool place. Avoid exposing them to extreme temperatures or moisture. If the car gets dirty, use a soft, dry cloth to clean it. For the controller, you can gently wipe it with a slightly damp cloth. Always remember to turn off the power when you're done playing to save battery life.
