For the next 3 days up to 100 l / m² warned in my local weather forecast before rainfall, the station shows but brave "sunny" to. Trying as recommended in the manual, readjust, failed miserably at trying to help the miserable remote (reacts to suit your mood!) To determine the location: system crashes and the date and time are set to initial. What is a menu item "System Upgrade" if the call is not? In the operating instructions you have embezzled concrete evidence of setting the date and time, and so you have to laboriously along the lines of "Learning by doing". My recommendation: Buy Dear suitable weather station and next to make cherished pictures in classic wooden caddy.
