Using this wall clock is easy. First, find a nice spot on your wall where you want to hang it. Then, use a nail or a wall hook to hang it up securely. Next, open the battery compartment at the back and insert one AA battery (you'll need to buy the battery separately). Once the battery is in, the clock should start working right away. When it comes to maintenance, keep it away from water and excessive heat. If it gets dusty, you can use a soft, dry cloth to gently wipe it clean. Also, remember to replace the battery when the clock starts to slow down or stop ticking. That's all you need to know to enjoy your Lilo & Stitch wall clock!
