[. . . ] 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. The operation of this product is simple and straightforward. 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 Battery compartment RESET key The Temperature Transmitter Function keys Features of the Weather Station · 4 digits LCD time display Holder · 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. [. . . ] 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 belowthe 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 one hPa (millibar); 0. 03 inHg (inches of mercury) = 1hPa) 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 "0" in the middle of this scale is equal to the current pressure and each change (±1, ±3, ±5, and ±7) is how high or low in "hPa" the past pressure was compared to the current. If the bars are rising, it means that the weather is getting better due to the increase of air pressure. If the bars go down, it means the air pressure has dropped and the weather is expected to get worse from the present time "0". Checking for 433MHz reception The Weather Station will automatically start scanning for the 433MHz signal after the batteries are inserted. If the outdoor temperature is not displayed after about 30 seconds, then check the following list before resetting the units (see Resetting below): 1. 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). [. . . ] The specifications of this product may change without prior notice.
