43
frequency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled Weather Station receives
this signal and converts it to show the precise time in summer or
wintertime.
The quality of the reception depends greatly on the geographic location.
In normal cases, there should be no reception problems within a
1,500km radius around Frankfurt.
After the temperature and humidity reception is completed in initial setup,
the DCF tower icon in the clock display will start flashing in the upper
right corner of the first section of the LCD. This indicates that the clock
has detected the presence of a radio signal and is trying to receive it.
When the time code is received, the DCF tower becomes permanently lit
and the radio-controlled time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does
not appear at all, then please take note of the following:
• Recommended distance to any interfering sources like computer
monitors or TV sets is a minimum of 1.5 - 2 meters.
• Within ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please
place the unit close to a window and/or point its front or back
towards the Frankfurt transmitter.
• During nighttime, the atmospheric disturbances are usually less
severe and reception is possible in most cases. A single daily
reception is adequate to keep the accuracy deviation below 1
second.
