SONIO 2.0 – Radio-controlled alarm clock with thermometer
• The clock will now scan the DCF frequency signal and the DCF symbol
flashes on the display. When the time code is successfully received after a
maximum of 15 minutes, the radio-controlled time, the date, the day of the
week and the DCF symbol will be shown steadily on the display.
• The clock automatically scans the time signal at 2:00, 3:00 and 4:00 a.m.
every day to maintain accurate timing (less disturbances).
• You can also start the initialization manually. Press the – button for 3 seconds.
The DCF reception symbol will be flashing.
• Press the – button again during the active DCF77 signal reception to stop
scanning the DCF time signal.
• There are three different reception states:
flashing symbol – reception is active
solid – reception is very good
No symbol – no DCF reception
• By default, the DCF reception is activated and after successful reception of the
DCF signal no manual time setting is necessary.
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmit-
ting distance, etc.), the time can be set manually. The DCF reception symbol
disappears and the clock will then work as a normal quartz clock (see: Manual
setting of the clock and calendar).
• The day-of-week language is German.
Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by
the Physikalisch Technische Bundesanstalt based in Braunschweig (Brunswick),
Germany. It has a time deviation of less than one second in one million years.

SONIO 2.0 – Radio-controlled alarm clock with thermometer
The time is coded and transmitted from Mainflingen near Frankfurt via the fre-
quency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately
1,500 km. Your radio clock receives the signal, converts it and always shows the
exact time. The adjustment to Daylight Saving Time (summer/winter time) is
automatic. In Daylight Saving Time the DST symbol
The reception quality depends mainly on geographic location. Normally there
should be no reception problems within a 1,500 km radius around Frankfurt.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like computer screens
or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the received
signal is naturally weakened. In extreme cases, please place the unit close to
a window to improve reception.
• During night-time, the atmospheric interference is usually less severe and
reception is possible in most cases. A single daily reception is adequate to
keep the accuracy deviation under 1 second.
7. Operation
• Important: The device cannot be operated during the DCF time-signal recep-
tion.
• The device will automatically quit the setting mode if no button is pressed for
15 seconds.
• Press and hold the + or – button in setting mode for fast mode.
7.1 Manual setting of the clock and calendar
