Pressure sensitivity setting
The pressure threshold for weather forecasting can be set from 2 ~ 4hPa (default 2hPa). Areas that experience
frequent changes in air pressure require a higher hPa setting compared to areas where the air pressure is more
stable. For example when 4hPa is selected there must be a fall or rise in air pressure of at least 4hPa to change
the weather forecast icon.
Storm threshold sensitivity setting
When a dramatic change in pressure is measured the weather icons (rain and clouds) will begin to flash
indicating a storm. Similar to the general pressure sensitivity setting it is possible to adjust the storm threshold
sensitivity form 3 ~ 9hPa (default 4hPa). When there is a pressure drop higher that the threshold over a period
of 3 hours, the storm forecasting will be activated. The clouds, rain icon and tendency arrows will flash for 3
hours indicating the storm warning feature has been activated.
8.3 UV index
Index intensity
0 ~ 2 low
3 ~ 5 moderate
6 ~ 7 extreme
8 ~ 10 high
11 + very high
Note: table based on average adult persons with pale skin and is for indication only. People with a sensitive
skin or children may already suffer from UV-related problems when exposed to even low UV intensities.
8.4 Reset to factory defaults
Press and hold the  button [c] for ±20s to reset the base station to factory default settings.
Note that the memory is also cleared.
9. PC connection
 The receiver can hold up to 4,080 weather data entries (with date and time) in its internal memory. This
memory is non-volatile (EEPROM) and will be preserved in case of a power failure (e.g. battery
replacement). When memory is full, the oldest data sets are overwritten.
 It is possible to read, copy, store and print this memory data by connecting the receiver to a PC (not incl.)
running the appropriate software.
Notes:
When memory is full (all records, i.e. 4080 entries), the oldest data sets are automatically overwritten. We
recommend taking backups via PC on a regular basis to retain all recorded data.
