Using your Bat - Radio replica is easy. Just press the front button, and the front panel will light up. The extendable antenna can be pulled out to make it look even more like the one in the show. Remember, the battery is only for the light - up feature, so don't expect any sound. When it's time to change the battery, use a small screwdriver to open the battery compartment at the back. Keep the Bat - Radio away from water and rough handling to prevent damage. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. Enjoy your piece of the 1966 Batman TV series magic!
