Note:
In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is due to a random security code
assigned by the transmitter at start-up. This code must be received and stored by the weather station in the first 3 minutes of power being supplied to the
transmitter.
DCF 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 1,500 km radius of
Frankfurt.
DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at 03:00 am, then the next reception takes place the next hour and
so on until 06:00am, or until the reception is successful. If the reception is not successful at 06:00 am, then the next attempt will take place the next day at
02:00 am.
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.
