Recommended from 3 years. LED source that does not overheat. 3 functions in one product: educational alarm clock, digital and analogue clock, night light. Works with power cable (included) and/or batteries (3 AA, not included). Material: ABS plastic. Dimensions: 15 x 9 x 20 cm. Contents: 1 educational alarm clock, 1 cable. This 3-in-1 educational alarm clock is the perfect solution for teaching your child when it's time to go to sleep and when to get up. Even the youngest children who are not yet able to tell the time can develop a sense of time and regulate the day-night rhythm. When the koala is asleep, the child understands that it is still time to go to sleep (even if it wakes up during the night), and at the time set by the parents, the koala lights up and the child knows that it is time to get up. It is equipped with a dual digital and analogue display that lights up red in night mode and green in day mode, and has a soothing night light with 2 selectable light intensities. The koala's face rotates to indicate that it is asleep in night mode and awake in day mode. It is easy to programme and has a child lock that does not allow the child to change the parent's settings.
