Once the batteries are in place, all segments of the LCD will light up briefly.
Following the time as 0:00 will be displayed and indoor temperature. If these
are not displayed after 60 seconds, remove the batteries and wait for at least
10 seconds before reinserting them.
3.
After inserting the batteries, the temperature station will start receiving data
from the transmitter. The outdoor temperature and the signal reception icon
should then
be displayed on the temperature station. If this does not happen
after 3 minutes, the batteries will need to be removed from both units and
reset from step 1.
4.
In order to ensure sufficient 868 MHz transmission however, this should under
good conditions be a distance no more than 100 meters between the final
position of the Temperature station and the transmitter (see notes on
“
Mounting
” and “
868 MHz Reception
”).
5. Once the remote temperature has been received and displayed on the
temperature 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:
In the event of changing batteries of the units, ensure the batteries do not spring free
from the contacts. Always wait at least 1 minute after removing the batteries before
reinserting, otherwise start up and transmission problems may occur.
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)
