The Weather Tendency Indicator - TFA WS-9630N Instruction Manual

If the weather station is moved to another location significantly higher or lower than its initial
standing point (for example from the ground floor to the upper floors of a house), remove the
batteries and re-insert them after about 30 seconds. By doing this, the weather station will not
mistake the new location as being a possible change in air-pressure when really it is due to the
slight change of altitude. Again, disregard weather forecasts for the next 12 to 24 hours as this will
allow time for operation at a constant altitude.

THE WEATHER TENDENCY INDICATOR

Working together with the weather icons are the weather tendency indicators (located near the
Weather boy). When the indicator points upwards, it means that the air-pressure is increasing and
the weather is expected to improve, but when indicator points downwards, the air-pressure is
dropping and the weather is expected to become worse.
Therefore, user may see how the weather has changed and is expected to change. For example, if
the indicator is pointing downwards together with cloudy icons, it means that the last noticeable
change in the weather was when it was sunny (the sunny icon only). Therefore, the next change in
the weather will be the cloudy icons since the indicator is pointing downwards.
