[. . . ] If the outdoor temperature signal goes to dashes restart from step 1 and try a new location. 6. HOW TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO TRANSMITTER The outdoor thermo-hygro transmitter uses 2 x AAA, IEC LR3, 1. 5V batteries. To install and replace the batteries, please follow the steps below: 1. Replace the battery cover on the unit. 4 HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION The weather station uses 2 x C, IEC LR14, 1. 5V batteries. To install and replace the batteries, please follow the steps below: 1. [. . . ] 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. 20 Note: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD. AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND) The right side of the second section on the LCD shows the air pressure history bar graph. Air pressure unit in inHg Air pressure trend over the last 12 hours The bar graph indicates the air pressure history trend over the past 12 hours in 7 steps (+0. 15, +0. 09, +0. 03, 0, -0. 03, -0. 09, and ­0. 15 inHg) at the points 0, -3, -6, -9 and -12 hours. The "0h" represents the current full hour air pressure recording. The left column shows the unit in "inHg" (0, ±0. 03, ±0. 09, ±0. 15). The "0" in the middle of this scale is equal to the current pressure and each change (±0. 03, ±0. 09, ±0. 15) represents how high or low, in "inHg" scale, the past pressure was compared to the current pressure. 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 "0h". 21 Note: For accurate barometric pressure trends, the weather station should operate at the same altitude for recordings (i. e. it should not be moved from the ground to the second floor of the house). When the unit is moved to a new location, discard readings for the next 12 hours. DISPLAY OF INDOOR TEMPERATURE/HUMIDITY DATA The indoor temperature and humidity are measured automatically and displayed on the first section of the LCD. Indoor temperature in °F Indoor humidity in RH% DISPLAY OF OUTDOOR TEMPERATURE/HUMIDITY DATA The last section of the LCD display shows the outdoor temperature and humidity and a reception symbol. Outdoor humidity in RH% Reception symbol Outdoor temperature in °F 22 DISPLAY OF INDOOR/OUTDOOR MAXIMUM AND MINIMUM RECORDS Press the MIN/MAX key several times to view the MIN/MAX indoor temperature, and MIN/MAX outdoor temperature sequentially. Date and time of recordings will be shown for outdoor temperature data. Recorded MIN/MAX outdoor temperature time Recorded MIN/MAX outdoor temperature date Outdoor temperature in F RESETTING THE MAXIMUM/MINIMUM RECORDS To reset the MIN/MAX records, press and hold the MIN/MAX key for 2 seconds. This will reset ALL minimum and maximum temperature records to current readings. 23 LOW BATTERY INDICATORS Low battery indicator will show on the LCD when the batteries of weather station or transmitter require changing. THERMO-HYGRO TRANSMITTER The reception distance of the thermo-hygro transmitter may be affected by the temperature. Please bear this in mind when placing the transmitter. 915 MHz RECEPTION The weather station should receive the outdoor data within 80 seconds after set-up. If the outdoor data is not received 80 seconds after setting up (or the outdoor temperature shows "- - -" during normal operation), please check the following points: 1. The distance of the weather station or transmitter should be at least 5 to 6. 5 feet (2 ­3 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 915 MHz signal frequency can also cause interference. 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 24 reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur. [. . . ] This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 36 Reorient or relocate the receiving antenna. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ]
