3.1.2 Main unit battery installation
Install 4 x 1,5V AA Alkaline batteries (not included) in the battery compartment to activate
the display.
•
Open the battery compartment at the back of the unit.
• Install 4 x 1,5V AA (LR06) Alkaline batteries following the polarity indicated inside
the battery compartment.
• Close the battery compartment.
3.1.3 Low battery indication
The batteries must be replaced as soon as the low battery icon of the main unit
or the outdoor sensor is displayed
on the main unit.
4 Meteotime
4.1 Receiving the Meteotime signal.
Meteotime is an innovative system in the communication of
weather forecasts (www.meteotime.com).
® The Meteotime-Icon and the brand "Meteotime" are
internationally registered and protected!
Meteotime does get the weather forecasts twice a day from
the weather office Meteotest (www.meteotest.ch).
Meteotime adapts the weather data technically to the system
and sends it to Physikalisch-Technische Bundesanstalt (PTB)
in Germany und METAS in Switzerland.
Both offices will transmit the weather date at precisely defined
time slots all over Europe.
The coverage of Europe with weather forecasts is optimal
thanks to the two time strong transmitters, DCF77 (PTB) and
HBG (METAS) (see illustration).
The 302NE has the Meteotime Technology built and does
receive and decode the data.
More information can be found on www.meteotime.com.
4.2 Radio Controlled Clock
DCF77 (PTB) and HBG (METAS) will also transmit the time signal, which is regulated by 4 atomic clocks and in average
deviates less than 1 second in 2 million years.
Because of that, the 302NE will indicate always the exact time.
4.3 Environmental reception effects
It is expected that the signal can cover a distance of 2,000 km from the transmitter.
However, some environmental effects may affect the transmitting distance.
Avoid the following situations to maximize the radio controlled clock and Meteotime signal reception:
For more information, visit www.ptb.de.
• Long transmitting distance
• Nearby mountains and valleys
• Among tall buildings
• Near railway, high voltage cable, etc.
• Near freeway, airport, etc.
• Near construction site
• Inside concrete buildings
• Near electrical appliances
• Bad weather
• Inside moving vehicles
• Nearby metallic structures
• Weak batteries
