13. Battery Change
a) Weather Station
The battery must be replaced when the display contrast is very low.
Copy the measured data onto the PC before changing the batteries; otherwise, they will be lost.
b) Outdoor Sensor
Check the solar module from time to time, clear if of foliage and snow and clean if.
The outdoor sensor receives a new safety code every time the batteries are inserted. Therefore, the weather station usually no longer displays measured data or DCF time/date. Therefore, proceed again as during initial commissioning (see chapter 10).
Back up any measured data stored on the weather station on the PC; otherwise, they will be lost.
14. Troubleshooting
With this weather station, you purchased a product built to the state of the art and operationally safe. Nevertheless, problems or errors may occur. The following contains descriptions for the removal of possible interference.
No reception of the outdoor sensor signal
• The distance between weather station and outdoor sensor is too large. Change the installation site of the weather station or outdoor sensor.
• Objects or shielding materials (metallised insulated glass, reinforced concrete, etc.) interfere with radio reception.
The weather station is too close to other electronic devices (TV, computer). Change the site of setup of the weather station.
• The outdoor sensor batteries are weak. Observe Chapter 9.
• Very low outdoor temperatures (less than -20 °C) decrease battery performance. Wait until the temperatures have increased again.
• Another transmitter on the same or adjacent frequency interferes with the outdoor sensor radio signal. It may be helpful to reduce the distance between the weather station and outdoor sensor.
• Remove the batteries from the weather station and the outdoor sensor and proceed as described in chapter 10.
No DCF Reception
• The outdoor sensor is installed close to other electronic devices or close to electrical lines.
Select a different mounting site (observe correct alignment, mark “N” on the wind direction sensor must point North).
• After inserting the batteries in the outdoor sensor (DCF receiver is integrated in the temperature/humidity sensor and is supplied with power by it), it will take at least 5 minutes before the DCF signal is received and evaluated. Only then will the outdoor sensor transfer the DCF data to the weather station.
Therefore, wait for at least 5 - 10 minutes before the weather station displays the DCF time and date.
• If the first reception attempt of the DCF-receiver fails, it will try again every full hour.
A single successful reception attempt suffices to keep the time deviation of the clock in the weather station to less
