Each side of the clock performs different functions. Just flip it for time/date, alarm, temperature or timer. Batteries are sold separately; 2 pcs AAA 1.5V required. It doesn’t take up a lot of space and it’s simple to use – even while half-asleep in bed. It’s quick and easy to switch between 4 functions – time and date, temperature, timer, and countdown – just by turning the clock to a new side.
