Setup
Remove the protective film from the display of the alarm clock. Open the battery compartment on the
backside of the device and insert a 1.5V AA R6/LR6 battery in the correct polarity. Close the battery
compartment.
Radio time signal reception starts automatically after inserting the battery and the alarm clock will
beep once. The radio tower indicator will blink on the display. This process can take 3-10 minutes.
Note: Please do not move the alarm clock during the reception process.
The alarm clock synchronizes the internal clock every day from 01:00 to 04:00 on each full hour. If
reception is unsuccessful, the clock will reattempt reception at 05:00 and 06:00. Please set the time
manually, if reception fails (see "Basic settings").
If reception is successful, the radio tower indicator appears permanently on the display and the
time, date and day of the week are set automatically. During daylight saving time, DST appears on
the display next to the radio tower indicator.
Reception problems
The DCF77 radio signal is transmitted from a location near Frankfurt am Main and can be received
within a radius of approximately 1500 km around Frankfurt am Main. However, there are some
obstacles and sources of interference, which may substantially hinder reception. If your weather
station does not correctly receive the DCF77 radio signal, please hang or place the weather station
in a different location at your site. Please note that devices such as computers, telephones, radios
and televisions may cause electromagnetic radiation with can interfere with the DCF77 signal
reception. Other possible detriments to reception are: strong building insulation (metal building
materials), nearby mountains or atmospheric interference. It may also be necessary to replace the
batteries.
