another floor). In areas where the weather is not largely affected by the
change of air pressure, the sensitivity setting should be set to 1.
A. WEATHER
ICONS
There are 3 possible weather icons that will be displayed in the
FORECAST LCD:
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).
These icons indicate the expected weather change in the next 12 to
24 hours. The icon does not give an exact prediction of the
weather, however it should be viewed as a generalization of the
expected weather change (for example a “sunny” icon indicates the
weather is expected to improve).
The weather icons change when the unit detects a change in air
pressure. The icons change in order, from “sunny” to “partly
sunny” to “cloudy” or the reverse. It will not change from “sunny”
directly to “rainy”, although it is possible for the change to occur
quickly. If the symbols do not change then the weather has not
changed, or the change has been slow and gradual.
B. WEATHER TENDENCY ARROWS
Other possible displays in the FORECAST LCD are 2 weather
tendency arrows, one that points up (on the left side of the LCD)
and one that points down (on the right side of the LCD). 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, an arrow pointing
down indicates that the air pressure is decreasing and the weather
