Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be sunny with clouds). Clouds with Rain—indicates that the weather is expected to get worse (not that the weather will be rainy). The weather icons change when the unit detects a change in air pressure.
TROUBLESHOOTING If your clock does not receive a signal please check the following: Battery - The clock must have a fresh battery to receive and process the time signal. When the battery drops below 1.25 volts the clock indicates that it is time to change the battery by advancing the second hand in two-second steps. The operating voltage range is 1.25 to 1.75 volts. Location - Try a different location, ideally near a window.
