Dcf Radio Controlled Time - La Crosse Technology Weather Station Instruction Manual

IMPORTANT:
Transmission problems will arise if the setting for additional sensors is not followed as described above.
Should transmission problems occur, it is necessary to remove the batteries from all units and start again
the set-up from step 1.
9. Once the remote temperature has been received and displayed on the Weather station, the DCF
time (radio controlled time) code reception is automatically started. This takes typically between 3-5
minutes in good conditions.
If after 10 minutes, the DCF time has not been received, press the SET key to manually enter a time
initially.
Note:
Daily DCF reception is done at 02:00 and 03:00 every day. If the reception at 03:00 is not successful, then
at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at 06:00 is still
not successful, then the next try takes place at 02:00 next day.
If reception is successful, the received time will override the manually set time. The date is also updated
with the received time. (Please refer also to notes on "DCF-77 Radio Controlled time" and "Manual Time
Setting")

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
