4.4 Data transfer
Meteotime sends the data during precisely defined time slots in accordance with UTC (Coordinated Universal Time),
previously known as Greenwich Mean Time (GMT).
• Central Europe has during the winter UTC+1, during the summer UTC+2
• Great Britain and Portugal have during the winter UTC, during the summer UTC+1
Forecast transmission times (UTC):
•
22h00 - 3h59 - the actual (new) day (today)
• 04h00 - 09h59 - the next day (tomorrow)
• 10h00 - 15h59 - the following day (the day after tomorrow)
• 16h00 - 18h59 - the day following this (two days after tomorrow)
• 19h00 - 21h59 - the 30 additional regions
If the received data, during the above time slots, is incomplete or at times interfered, the forecast, or parts of them, will
be missing.
4.5 Outdoor sensor reception
Do not place the weather station and outdoor sensor next to each other, otherwise there may be reception problems
due to radio interferences. Keep a distance of at least 1 m between the two devices.
The maximum transmission range between outdoor sensor and weather station is up to 30 m under optimal conditions.
The range will be reduced by many factors:
•
Walls, reinforced concrete ceilings
• Trees, bushes, earth, rocks
• Metal & conducting objects (eg radiators)
• Broadband interferences in residential areas (DECT telephones, mobiles, radio controlled headphones, radio-
controlled speakers, other radio-controlled weather stations, babyphones etc.)
• It is advised to limit the distance between the weather station and the outdoor sensor.
5 Getting started
5.1 Meteotime receptions icons
Once the battery is installed, the main unit will automatically scan for the radio-controlled clock signal and the
Meteotime weather signal.
•
The time and date will appear in a few minutes.
• After the time and the date signal is being received successfully, the display shows ‘SELECT COUNTRY’ and
then ‘FRANKFURT’ (or the previously set default city), in the information window. (See chapter “6.1 Setting the
country and city”).
• Since there is a large amount of Weather information for all regions and days, the unit needs about 24 hours from
the time of the initial setup to complete the reception of all data. Until the weather information is received, the
weather icons will flash.
• If the unit is able to receive the Meteotime signal successfully, the Meteotime icon will be displayed.
• When no signal is received after 24 hours, will be displayed. Check if there are potential sources of
interference on the unit. (see chapter “4.3 Environmental reception effects”).
A. Today’s weather forecast received
B. The weather station is able to receive the Meteotime weather signal
C. Tomorrow’s weather forecast received
D. The day after tomorrow weather forecast received
E. Two days after tomorrow weather forecast received
5.2 Test the reception quality
You are able the test the reception quality and to look for a better location.
•
Press the TEST - button . ‘SCAN’ is displayed in the information
window .
• Move the unit to find a good location:
– is flashing: The test is running and the Meteotime signal reception is
good. You are able to leave the device in this position.
– is flashing: The test is running and the Meteotime signal reception is
poor. You need to keep on looking for a better location.
• The test will take around 1 minute.
• You can restart the test with the TEST - button at any time.
• Press the TEST - button also to stop the test.
