ABOUT WWVB (Radio Controlled Time) The NIST (National Institute of Standards and Technology--Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time signal continuously throughout the United States at 60 kHz. [. . . ] However, due to the nature of the Earth's Ionosphere, reception is very limited during daylight hours. The temperature clock will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per 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. For more information about WWVB please see the NIST website at http://www. boulder. nist. gov/timefreq/stations/wwvb. htm QUICK SET-UP GUIDE Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. Place the batteries into the remote temperature sensor first then into the temperature clock. (All remote temperature sensors must be started before the temperature clock) DO NOT PRESS ANY BUTTONS FOR 10 MINUTES. 4. In this time the temperature clock and remote temperature sensor will start to talk to each other and the temperature clock will show both the indoor temperature and an outdoor temperature. If the temperature clock does not display both temperatures after the 10 minutes please retry the set up as stated above. After both indoor and outdoor temperatures are displayed for 10 minutes you can place your remote temperature sensor outdoors and set your time. 15 16 The remote temperature sensor should be placed in a dry, shaded area. Any walls that the signal will have to pass through will reduce distance. An outdoor wall or window will have 20 to 30 feet of resistance and an interior wall will have 10 to 20 feet of resistance. NOTE: Fog and mist will not harm your remote temperature sensor but direct rain must be avoided. To complete the set up of your temperature clock after the 10 minutes have passed please follow the steps below. DETAILED SET-UP GUIDE VI) BATTERY INSTALLATION Note: To avoid start-up problems make sure that the batteries do not spring free. Place your thumb over the two air-vent slots on the face of the remote temperature sensor, push down gently, and slide battery cover down and off. The batteries will fit tightly (to avoid start-up problems make sure that they do not spring free during installation). 3) Replace the battery cover. temperature, the date as "1/ 1", the weekday as "MON", and the remote temperature will be displayed (within three minutes). Also, the time will appear as "-:--" for approximately 1 minute. The WWVB search is automatically initiated, and a tower icon appears and flashes with the time colon (no tower icon will appear if the WWVB is too weak to be detected, and the time display will remain on "-:--"). While the WWVB search is being conducted various numbers will appear in the time display. Within 10 minutes the temperature clock will either display the WWVB time, or discontinue the search if the time is not found. [. . . ] XI) MAINTENANCE & CARE Extreme temperatures, vibrations, and shock should be avoided to prevent damage to the units. Do not use solvents or scouring agents--they may mark and damage the displays and casings. Immediately remove all low powered batteries to avoid leakage and damage.
