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.

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.

2.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: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD.
