It has comprehensive weather data for you — including 30-hour bar ometric pressure, forecasts, dew point, wind chill, tidal reports, sunrise, moonrise and more. The STX7500 also has elegant info delivery, with a clear, easy to read blue screen s howing scrolling weather alerts. Set up is simple 1. Place the main station in your home — the bright back-light makes it a perfect alarm clock, or the mounting brackets make it perfect for any wall. 2. Program the main station.3. Place the remote sensor outside your home.4. Access your weather data anytime at a glance. Set up your remote sensorYour first step is to set up the STX7500 remote sensor. The remote device will read external conditions and automatically send t hem to the main station inside your home. 1. Open up the back panel of the remote sensor and add two AA (1.5V) batteries (not included).2. Just above the batteries is a switch which lets you choose which “channel” to broadcast on. Unless you plan to have multiple remote devices (which is unlikely), just keep the setting on channel 1. 3. Find the button which is marked C/F, for Celsius or Fahrenheit, located on the back of the unit. Choose the temperature metri c that you would prefer by pressing the button until your preference is displayed. Set up your anemometerYour second step is to set up your STX7500 wind anemometer. 1. Mount your wind anemometer near your outdoor sensor.2. Attach it to your outdoor sensor by connecting the included cable.

You will set the current weather, location, and other setti ngs. Programming the main unit1. Open up the battery panel of the main station device and add four AA (1.5V) batteries (not included). The unit can also be op erated using the supplied AC adaptor. Plug the barrel end of the adaptor into the jack located on the bottom of the STX7500; plug the other end into a wall outlet. 2. Main unit will light up entire display, and a sound will tell you unit is defaulting to initial settings.3. DO NOT TOUCH ANY BUTTONS FOR 10 MINUTES, WHILE THE STATION LOOKS FOR THE OUTDOOR SENSOR AND SCANS FOR THE WWVB SIGNAL.4. The two devices will begin communicating in this time. You should see the main station pick up a temperature and channel read ing. This shows that the two devices are in communication. 5. Place the remote device outside the house. a. Fog and mist will not harm your remote sensor, but direct rain should be avoided.b. The sensor has a range of 30 meters, but intervening walls will lower that number. An outdoor wall or window may have a 20 to 30 foot resistance. c. Consider mounting your device on an outside wall, directly opposite to the room where you plan to have your main station. 6. Once you have placed your outdoor sensor, check the main station to make sure the two devices are still communicating. Setting the WeatherTo begin, you must input the current weather conditions outside your house. This is because the forecaster technology works usi ng current conditions to predict future conditions. 1. Immediately after set up, the weather icon will be flashing for 15 seconds. 2. Press “+” or “-” on the back of the unit to input the correct weather outside. It is recommended that you set your first forec ast based on a local weather report. 3. Once you have established current weather, press the “REL/ABS” button, located on the back of the unit, again to exit4. The main station will start to forecast 6 hours after the current weather is entered . 5. When the main station begins forecasting, you will see one of 6 different symbols in the weather forecast. This is your forec ast for your area. The forecast is for 6 hours ahead. 6. At any time you can reset the weather forecast by holding down the “REL/ABS” button for 3 seconds. Then follow steps 2 and 3 again to set the new forecast. 7. When setting the weather, please note: a. If the outdoor sensor reads below 0°C and you have input the weather to “rain” or “heavy rain” then your main station will di splay snow b. The weather conditions should be reset if you change the altitude. Setting Clock AutomaticallyAfter the main station has finished searching for the remote sensor, it will proceed to scan for the “WWVB” signal — this is an atomic clock transmission which is sent all across the United States.1. Buttons will not function while station is scanning for WWVB time signal.2. While scanning the RCC icon will flash on the main station. 3. When the RCC icon stops flashing, the main station has successful updated with the correct time. a. Your main station will automatically rescan for WWVB time signal every night at 2:00 a.m.. If the first attempt fails, statio n will scan again at 3:00, 4:00, and 5:00 a.m. b. To manually start a new time scan, press and hold the “RCC” button, located on the back of the unit, for 3 seconds. 4. If the reception fails, the RCC icon will disappear. a. If reception fails, the main station will attempt to rescan for signal 4 times. Each time …
