[. . . ] Quick Set Up on Page 1 ­ 2 Complete Manual Starts on Page 3 308-805 QUICK SET UP: Forecast Icons Displays Time and Alarm Time Function Buttons Alarm Icon Displays Date or Heat Index / Dew Point Within 3 minutes the weather station will beep and the outdoor temperature should be displayed on the LCD. If the outdoor temperature is not displayed after 3 minutes, hold the SEARCH button on the main unit to search for outdoor sensor. Then press the TX button on the sensor to send signal. If it still does not receive the outdoor temperature, remove AC power and batteries from the receiver, remove the batteries from the transmitter and go back to step 1 of the set up. [. . . ] x Insert fresh alkaline batteries into the transmitter, observing the correct polarity Press the TX button to send a signal after the display is powered up. Keep the transmitter 5-10 feet from the weather station. x Within 3 minutes the station will beep and the outdoor temperature should be displayed on the Weather station. If the outdoor temperature is not displayed after 3 minutes hold the SEARCH button on the main unit to search for outdoor sensor. Then press the TX LIGHT ON/OFF AUTO ROTATE IN / OUT 1 step backward when setting Turn On or Off Auto-switch between Turn On or Off continuous indoor/outdoor data. backlight on a/c adapter WWVB RADIO CONTROLLED TIME The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2, 000 miles away through the internal antenna in the atomic weather station. However, due to the nature of the Earth's Ionosphere, reception is very limited during daylight hours. The atomic weather station will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST atomic weather station in Boulder, Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second a day. These physicists have created an international standard, measuring a second as 9, 192, 631, 770 vibrations of a Cesium 133 atom in a vacuum. This atomic weather station regulates the WWVB transmitter. WWVB RECEPTION icon with full signal strength will appear on screen if the reception of atomic time is successful. The atomic weather station will have a daily synchronization at 02:03 and 03:03 everyday. Each reception cycle is minimum 2. 5 minutes and maximum 10 minutes. In normal mode, press the RCC button until the reception icon appears to enforce searching of radio-controlled clock signal. If this icon disappears afterwards, radio time signal is not available at the moment. x x x Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 6 feet (2 meters). Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Fort Collins, Colorado, transmitter. During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. [. . . ] A low battery icon will display next to the outdoor temperature when the transmitter batteries are low and next to the indoor temperature then the batteries in the weather station are low. MAINTENANCE Do not expose the display to extreme temperatures, vibration or shock. The product is not to be used for medical purpose or for public information, but is determined for home use only. x The specifications of this product may change without prior notice. [. . . ]
