•
By pressing the “OUT” key, display of the stored MIN/MAX outdoor temperature and humidity with
simultaneous display of a MIN or MAX symbol in the upper center.
•
By pressing the “CH” key, display of outdoor sensors (up to three outdoor transmitters) 1, 2 or 3 in the center
will indicate from which sensor the current reading originates.
•
An antenna symbol in the upper center indicates that a signal is received from the transmitter(s).
DCF-77 RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is
coded and transmitted from Mainflingen near Frankfurt via 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.
Once the outdoor temperature and humidity are displayed on the Weather station after initial set-up, the DCF tower
icon in the clock display will start flashing in the upper left corner. This indicates that the clock has detected that
there is a radio signal present and is trying to receive it. When the time code is received, the DCF tower becomes
permanently lit and the 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
metres.
•
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.
