Common to weather forecasting, absolute accuracy cannot be
guaranteed. The weather forecasting feature is estimated to
have an accuracy level of about 75% due to the varying areas
the projection alarm clock station has been designed for use. In
areas that experience sudden changes in weather (for example
from sunny to rain), the projection alarm clock will be more
accurate compared to use in areas where the weather is
stagnant most of the time (for example mostly sunny).
If the projection alarm clock 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),
discard the weather forecast for the next 12-24 hours. By doing
this, the projection alarm clock 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.

WEATHER TENDENCY INDICATOR
Working together with the weather icons is the weather tendency
indicators (located to the right of the weather icons). 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.
Taking this into account, one can see how the weather has
changed and is expected to change. For example, if the indicator
is pointing downwards together with cloud and sun icons, then
the last noticeable change in the weather was when it was sunny
(the sun icon only). Therefore, the next change in the weather
will be cloud with rain icons since the indicator is pointing
downwards.
NOTE:
After setting up, readings for weather forecasts should be
disregarded for the next 12-24 hours. This will allow sufficient time
for the projection alarm clock to collect air pressure data at a
constant altitude and therefore result in a more accurate forecast.
NOTE:
Once the weather tendency indicator has registered a change in air
pressure, it will remain permanently visualized on the LCD.
