Using your DX Gochizo Set 07 is super easy. First, locate the new switch on the units. Flip it to switch between Lakia and Gochizo modes. If you want the voices to play automatically at random, just turn on the auto - chat mode. To enjoy the BGM tracks on the Doppudding, make sure it's powered on. When using the Gochizo with the DX Vrastum Gear or DX Henshin Belt Gavv (which you'll need to buy separately), just follow the standard connection steps. As for maintenance, keep the units away from water and extreme heat. If they get dirty, you can gently wipe them with a dry cloth. That's all you need to know to have a great time with your Gochizo set!
