2. Weather Tendency Arrows
Other possible displays in the TENDENCY LCD are 2
weather tendency arrows, one that points up and one that
points down. 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 is expected to become worse or remain poor. No
arrow means the pressure is stable.
A storm can be expected if there is a drop of 4 hPa or
more in less than 6 hours, the rain icon is displayed, and
the downward pointing arrow is flashing. The flashing
will stop when the air pressure stabilizes or begins to rise.

25.9°C), and the humidity is between 45% and 64%. A sad face
icon will be displayed when the temperature and humidity are
outside the mentioned ranges.
