[. . . ] Wireless Weather Station Instruction Manual Congratulations on purchasing this state-of-the-art Weather Station as an example of fine design and quality piece of engineering. By reading this instruction manual, users will receive a better understanding of the Weather Station together with the optimum benefit of all its features. The Weather Station Hanging Hole LCD Display Holder The Temperature Transmitter Features of the Weather Station · 4 digits LCD time display · Current indoor temperature display in degree Fahrenheit · Simultaneous minimum and maximum indoor temperature recordings · Current relative humidity display with "" Smilling or " " Sad face for comfort level reading. · 3 weather icons for weather forecasting · Weather tendency indicator · Relative air pressure inHg with adjustable reading ranges · Air pressure history for the past 72 hours (electronic barometer with barometric pressure and trend) · Current outdoor temperature display in degree Fahrenheit · Simultaneous minimum and maximum outdoor temperature recordings. [. . . ] 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 from both the Weather Station and transmitter 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 above and below 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 the 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. Storm warning indicator: The downward tendency indicator will flash if the air pressure has dropped by 4 hPa or more in the last 6 hours. Relative air pressure inHg Underneath the weather icons is the air pressure reading which is recorded constantly in inHg and the Weather Station displays this reading as the relative air pressure. Air pressure history (electronic barometer with barometric pressure and trend) Air pressure over the last 72 hours Air pressure scale (Each bar represents 1 hPa (millibar); 1hPa = 0. 03 inHg (inches of mercury)) The bar chart indicates the air pressure trend over the last 72 hours in 8 steps, 0, -1, -3, -6, -12, -24, -48 and -72 hours. The bar is plotted at each of the right (0, ±1, ±3, ±5, and ±7) compares the result. The distance of the receiver or transmitter should be at least 1. 5 to 2 meters away from any interfering sources such as computer monitors or TV sets. Avoid placing the receiver onto or in the immediate proximity of metal window frames. Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception. Neighbours using electrical devices operating on the 433MHz signal frequency can also cause interference. Note: When the 433MHz signal is received correctly, do not re-open the battery cover of either the transmitter or Temperature station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Resetting below) otherwise transmission problems may occur. The transmission range is around 25 m from the transmitter to the Temperature station (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Resetting below). The transmitter's transmitting range may be affected by exposure to extreme cold condition (-25°C) for long periods of time due to the nature of Alkaline batteries.
