5. Once the remote temperature has been recei ved 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.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time i s a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has a time deviation of less than one seco nd in
one million years. The time is coded and transmitted from Mainflingen near Frankfurt vi a frequency
signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radiocontrolled weather station receives this signal and converts it to show the precise time i n 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 t he 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 wi ll
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:
41
•
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.

For every sudden or significant change in the air pressure, the weather icons will update
accordingly to represent the change in weather. If the icons do not change, then it means either
the air pressure has not changed or the change has been too slow for the weather station to
register. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if
the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already
at their extremes.
The icons displayed forecasts the weather i n terms of getting better or worse and not necessarily
sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy
icon is displayed, it does not mean that the prod uct is faulty because it is not raining. It simply
means that the air pressure has dropped and the weather is expected to get worse but not
necessarily rainy.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours.
This will allow sufficient time for the weather station to collect air pressure data at a constant
altitude and therefore result in a more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather
forecasting feature is estimated to have an accuracy level of about 75% due to the varying areas
the weather station has been designed for use i n. In areas that experience sudden changes in
weather (for example from sunny to rain), the Weather station will be more accurate compared to
use in areas where the weather is stagnant most of the time (for example mostly sunny).
52
If the weather station is moved to another location significantly higher or lower than its initial
standing point (for example from the ground fl oor to the upper floors of a house), remove t he
batteries and re-insert them after about 30 seconds. By doing this, the weather station will not
mistake the new location as being a possibl e change in air-pressure when really it is due to the
slight change of altitude. Again, disregard weat her forecasts for the next 12 to 24 hours as this will
allow time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators (located near t he
Weather boy). When the indicator points upwards, it means that the air-pressure is increasi ng and
the weather is expected to improve, but when i ndicator points downwards, the air-pressure i s
dropping and the weather is expected to become worse.
Therefore, user may see how the weather has changed and is expected to change. For exampl e, if
the indicator is pointing downwards together wi th cloudy icons, it means that the last noticeabl e
change in the weather was when it was sunny (the sunny icon only). Therefore, the next cha nge in
the weather will be the cloudy icons since the indicator is pointing downwards.
53
The coming weather condition is expected to be more
Note:
•
Once the weather tendency indicator has regi stered a change in air pressure, it will remain
permanently visualized on the LCD.
•
When the tendency indicator is pointing to the right, it means that no pressure change has
been detected by the weather station from the begi nning. Therefore, the coming weather
condition is expected to be more or less the same as the current condition.
THE COMFORT LEVEL INDICATOR:
The comfort level indicator is located at the right of the weather boy icon:
Comfortable : A happy face icon “☺” indicating a temperature level between 20°C and
Uncomfortable : A sad face icon “” indicating any value outside the comfortable range.

868 MHz RECEPTION
The weather station should receive the temperature data within 5 minutes after set-up. If t he
temperature data is not received 5 minutes after setting up (not successfully continuously, t he
outdoor display shows “- - -” ), please check the following points:
Min outdoor
temperature
57
1. The distance of the weather station or transmitter should be at least 1.5 to 2 meters away
from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the weather station onto or i n the immediate proximity of metal window
frames.
3. Using other electrical products such as headphones or speakers operating on the same
signal frequency (868MHz) may prevent correct signal transmission and reception.
4. Neighbours using electrical devices operati ng on the 868MHz signal frequency can also
cause interference.
Note:
When the 868MHz signal is received correctly, do not re-open the battery cover of either the
transmitter or weather station, as the batteries may spring free from the contacts and force a false
reset. Should this happen accidentally then reset all units (see Setting up above) otherwise
transmission problems may occur.
The transmission range is about 100 m from the transmitter to the weather station (in ope n space).
However, this depends on the surrounding environment and interference levels. If no recepti on is
possible despite the observation of these factors, all system units have to be reset (see Setting
up).
