Using this VTech kids' watch is super easy. To see the cute picture of Gabby and Pandy Paws, just flip up the watch cover. To change the clock face, there should be a button on the side of the watch. Click it to cycle through the 10 options with Gabby and her friends. For the games, look for the game - start button. Once you start a game, follow the on - screen prompts to collect popcorn shapes, make milkshakes, etc. The alarm, timer, and cuckoo clock functions can be set through the menu on the watch. Remember to use only 1 x CR2450 battery. If the watch stops working, it might be time to change the battery. Keep the watch away from water and rough play to avoid damage. Wipe it with a soft, dry cloth if it gets dirty.
