[. . . ] If these are not displayed after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. After inserting the batteries, the weather station will start receiving data from the transmitter. The outdoor temperature and the signal reception icon should then be displayed on the weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1. [. . . ] 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. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny). 14 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 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 airpressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next 48 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 on the left and right hand side 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, you will see how the weather has changed and how it 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 (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 the air pressure, it will remain permanently visualized on the LCD. 15 INDOOR MIN/MAX TEMPERATURE RECORDS The current indoor temperature is displayed on the third section of the LCD. Minimum indoor temperature MIN icon (flashing) Maximum indoor temperature MAX icon (flashing) 1. Press and release the INDOOR/RESET key repeatedly, the current indoor temperature will alternate between the MIN/MAX temperature recordings and the current value. OUTDOOR MIN/MAX TEMPERATURE RECORDS The current outdoor temperature is displayed on the last section of the LCD. MIN icon (flashing) Minimum outdoor temperature MAX icon (flashing) Maximum outdoor temperature 16 1. Press and release the OUTDOOR key repeatedly, the current outdoor temperature will alternate between the MIN/MAX temperature recordings and the current value. RESET INDOOR AND OUTDOOR MIN/MAX TEMPERATURE RECORDS In normal display mode, press and hold the INDOOR/RESET key for 3 seconds to reset ALL indoor and outdoor minimum/maximum records to current values at the same time. LOW BATTERY INDICATOR Low battery indicator is displayed on the LCD when the batteries require changing. 915 MHz RECEPTION CHECK The weather station should receive the temperature data within 3 minutes after set-up. If the temperature data is not received 3 minutes after setting up (not successfully continuously, the outdoor display shows "- - -" ), please check the following points: 1. The distance of the weather station or transmitter should be at least 5 to 6. 5 feet (1. 5 -2 meters) away from any interfering sources such as computer monitors or TV sets. Avoid positioning the weather station 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 (915 MHz) may prevent correct signal transmission and reception. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference. 17 Note: When the 915 MHz signal is received correctly, do not re-open the battery cover of either the transmitter or weather station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur. The transmission range is about 200 feet/100 m from the transmitter to the weather station (in open space). However, this depends on the surrounding environment and interference levels. Do not use solvents or scouring agents as they may mark the LCD and casings. Special care shall be taken when handling a damaged LCD display.
