Using your mecha is a breeze. First, insert 2 LR521 batteries into the head to light up the LEDs. You can mix and match the various weapon accessories according to your preferred fighting style. Attach the weapons using the provided connectors. When not using the hands, store them in the hand storage component. Keep the mecha on the metal base for display. To keep it looking great, avoid exposing it to direct sunlight for long periods as it may fade the fluorescent paint. If it gets dirty, use a soft, dry cloth to gently wipe it. Always keep the warranty card safe as you'll need it if you want to get after - sales support from the manufacturer.
