Product specification

The radio alarm clock SONIO 2.0 is a refined version of the long-standing and successful TFA product.

The time is set exactly to the second via the DCF77 signal and the change from winter to summer time is automatic. The alarm clock also provides information about the day of the week and the date.

Two different alarm times e.g. for working days and weekends, you always wake up at the right time. For a pleasant wake-up, the alarm starts quietly and then gets louder and louder. The alarm can be set to three different volumes levels. If you don't want to get up straight away, you can trigger the snooze function with the large, dark red button on the top of the alarm clock, just turn around again and go back to sleep for a few minutes.

If you press the dark red button, the display is also brightly illuminated for a short time. If you want to see the time all night, you can choose a discreet and economical night lighting that switches on and off automatically via the integrated light sensor.

The integrated thermometer measures the room temperature and ensures a good climate in the bedroom. For a restful sleep, the temperature should not be above 18 ° C, but also not below 16 ° C.
