A.WEATHER ICONS

There are 3 possible weather icons that will be displayed at various times in LCD 3:

Sunny Sun with Clouds Clouds with Rain

Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).

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. The icons change in order, from “sunny” to “sun with clouds” to “clouds with rain” or the reverse. It will not change from “sunny” directly to “clouds with rain”, although it is possible for the change to occur quickly. If the symbols do not change, the weather has not changed (or the change has been slow and gradual).

B. WEATHER TENDENCY ARROWS

LCD 3 also displays the weather tendency arrows. One arrow points up and one

arrow points down, both arrows appear on the left-hand side of LCD 3 at different times. These arrows reflect current changes in the air pressure. An arrow pointing up indicates that the air pressure is increasing and the weather is expected to improve or remain good, and arrow pointing down indicates that the air pressure is decreasing and the weather is expected to become worse or remain poor. No arrow means the pressure is stable.

C.STORM WARNING

A storm can be expected if there is a drop of 4 hPa or more in less than 6 hours. The clouds with rain icon will be displayed and the tendency arrow that points down will be flashing—indicating the storm warning feature has been activated. The flashing will stop when the air pressure stabilizes or begins to rise.
