Using this Digivice is super easy. First, get 2 AAA batteries and put them into the battery compartment. Once the batteries are in, turn it on and start exploring the 8 different Digimon and their original dialogues. When not in use, keep it in a dry and cool place to prevent damage. Avoid exposing it to extreme temperatures or moisture. If you notice any issues, check the battery connection first. For long - term use, replace the batteries regularly. Have fun with your new 20th anniversary Digivice!
