Using this smart fridge is easy. First, put the 3 included AAA batteries in the designated battery compartment. Then, you can start storing your toy food and accessories in the pull - out freezer drawer. To have some fun, use the ice and water dispenser to make pretend 'chilled' drinks. Press the 6 buttons on the touchscreen to hear funny sounds. When it comes to maintenance, keep it away from water to avoid damage. If the fridge doesn't work, check the batteries to see if they need to be replaced. Also, don't use it roughly as it might break some of the interactive features.
