3. After inserting the batteries into the transmitter, the Weather station
will start receiving data from the transmitter. The outdoor
temperature data should then be displayed on the Weather 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. The Weather station can take up to 3 remote transmitters. If you
have purchased additional transmitters, follow step 2 for all extra
transmitters. However, ensure that you leave 10 seconds in
between the reception of the last transmitter and the set-up of the
following transmitter. The Weather Station will number the
transmitters in the order of set-up, i.e. the first transmitter will have
the temperature and humidity displayed with the number 1 against it
and so on.
5. After all the transmitters are set up, there is a testing period, during
which the display switches quickly between all the received
transmitters at random, according to which random transmission it
receives. The process will stop automatically if no keys are pressed
for a few minutes.
6. Once the remote data have been received and displayed on the
Weather station, the DCF-77 time code reception is automatically
started. This takes typically between 3-5 minutes in good conditions.
This time period is an excellent opportunity to locate the
transmitter(s) in suitable location(s) outdoors. In order to ensure
sufficient 433MHz transmission however, this should under good
conditions be no more than 100 meters from where the Weather
station will be finally positioned (see notes on “Positioning” and
“433MHz Reception”).
7. If after 10 minutes, the DCF time has not been received, use the
SET key to manually enter a time and date initially. The clock will
automatically attempt to receive the DCF time at each full hour.
When this 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 “Radio controlled Time Reception” and
“Manual Time Setting”).
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.
RESETTING
The Weather Station and the Temperature transmitter need to be reset
when one of the following conditions occur:
• Unsuccessful 433MHz signal reception.
• Malfunction on the units.
• Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute
before powering up the Weather Station again. Proceed from step 1 in
“Setting Up”.
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.
