This weather station is capable of detecting barometric pressure changes, and based on
the data collected, can predict the weather for the next 12 to 24 hours. The effective range
covers an area of 30 – 50km.

REMARKS:
* After setting up, reading for weather forecasts should be discarded for the
next 12-24 hours. This will allow sufficient time for the Weather Station to
operate 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 Weather Station has been designed for use in.
* If the Weather Station is moved to another location significantly higher or
lower than its initial standing point (e.g from ground floor to 1st floor of a
house), remove the batteries and reinsert them after about 30 seconds. By
doing this, the Weather Station will not make mistake of new location being a
possible change in air pressure. Again, discard the weather forecasts for the
next 12-24 hours as this allow time for operation at a constant altitude.
Note:
* Remote sensor Channel 1 will be used for weather indication.
