• Press and hold +/CH button for three seconds. The last registered transmitter (channel) will be cancelled.
• Press the RESET button on the outdoor transmitter. The transmission of the outdoor data will take place immediately.
6.3 Radio-controlled time reception
• After 3 minutes the clock will then scan the DCF (radio-controlled clock) frequency signal. The DCF reception symbol will
be flashing. When the time code is successfully received after a maximum of 7 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 1:00, 2:00 and 3:00 a.m. every day to maintain accurate timing (less dis-
turbances).
• If the reception is not successfully received, another DCF reception will take place the next full hour (up to 5 times).
• You can also start the initialization manually. Press the – /WAVE button for 2 seconds. The DCF reception symbol will be
flashing.
• Press the – /WAVE button again during the active DCF77 signal reception to stop scanning the DCF time signal.
• There are 3 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, transmitting distance, etc.), the time can be set manually.
The clock will then work as a normal quartz clock. (see: Setting of the clock, calendar and location).
Note on radio-controlled time
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.

The time is coded and transmitted from Mainflingen near Frankfurt via the frequency signal DCF-77 (77.5 kHz) and has a
transmitting range of approximately 1,500 km. Your wireless weather station receives the signal, converts it and always
shows the exact time. The adjustment to Daylight Saving Time (summer/wintertime) is automatic. In Daylight Saving Time
DST is shown on the display. The reception quality depends mainly on geographic location.
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 reception.
• The device will automatically quit the setting mode if no button is pressed for 20 seconds.
• Press and hold the +/CH or – /WAVE button in setting mode for fast mode.
7.1 Setting of the clock, calendar and location
• Press and hold the SET button in normal mode for three seconds to enter the setting mode.
• RC and the DCF reception symbol appear on the display and ON will be flashing.
• By default, the DCF reception is activated (RC ON) and after successful reception of the DCF signal no manual adjustment
is necessary.
• In the setting mode, press the +/CH or – /WAVE button if you want to deactivate the DCF reception (RC OFF).
