Using the Mega Wrex Alive remote - control truck is easy. First, make sure it's fully charged. To start, tap the impact sensor on the truck, and it will wake up and enter Hunt Mode. Use the remote to move it around and let it hunt. In Smasher Mode, guide it towards obstacles and watch it smash through them with its big tires. You can also try stunts by propping it on its back two wheels. When you're done playing, put it in Guard Mode so it can recharge. Remember to keep the remote and the truck away from water and rough play to avoid damage. Also, don't use the truck if the battery is low as it may not work properly. For maintenance, regularly check the wheels and the remote for any loose parts. If the lights or sounds seem weak, it might be time to change the batteries.
