Using the DX Ryuki RideWatch is easy. Just turn it on and enjoy the cool lights and sounds. When using it with the DX Ziku Driver, weapons, or the DX Time Machine, simply connect them as shown in the instructions. For safety, keep it away from small children who might swallow parts. To maintain it, clean it gently with a dry cloth. Don't expose it to water or extreme temperatures. If it stops working, check the batteries and replace them if needed.
