Using this Lilo & Stitch wall clock is a breeze. First, find a nice spot on your wall to hang it up. Make sure the wall can support the weight of the clock. Then, open the back cover and insert one AA battery. You're all set! Keep in mind that the battery is not included, so you'll need to buy it separately. When it comes to maintenance, simply use a dry cloth to wipe the clock's surface if it gets dirty. Avoid using any wet or abrasive materials as they might damage the plastic case or the clock face. And if the clock stops working, it's probably time to replace the battery.
