[. . . ] WS-8016U ATOMIC CLOCK WITH OUTDOOR WIRELESS TEMPERATURE Instruction Manual INTRODUCTION: Congratulations on purchasing this state-of-the-art Atomic Clock as an example of superior design and engineering. Providing WWVB radio-controlled time, date, time zone, indoor and outdoor temperature display, this innovative clock is ideal for home or office use. Operation of this product is simple and straightforward. By reading this operating manual, the user will however receive a better understanding of the Atomic Clock together with the optimum benefit of all its features. Note: In the event of changing batteries of the unit ensure that the batteries do not spring free from the contacts. [. . . ] The WWVB radio station derives its signal from the NIST Atomic clock 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 Clock regulates the WWVB transmitter. Once the outdoor temperature is displayed on the Atomic Clock, the WWVB tower icon in the clock display will start flashing in the top center of the LCD. This indicates that the clock has detected a radio signal and is trying to receive it. When the time code is received, the WWVB tower becomes permanently lit and the time will be displayed. If the tower icon flashes, but does not set the time or the WWVB tower does not appear at all, then please take note of the following: · 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 single daily reception is adequate to keep the accuracy deviation below 1 second. Note: In case the Atomic Clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc. ), the time can be manually set (please refer to notes on Manual time setting) DATE SETTING 1. The digits for the date will start flashing on LCD2 (Default setting 1). Set the desired date by use of the + key. Note: The date can only be set in conjunction with the selected month. For example, it is not possible to set the date 30 if the month of February is selected. Press and release the SET key to enter the "Weekday Setting". WEEKDAY SETTING 1. The weekday symbols will be displayed on LCD2 in the pre-set language and flashing. Set the desired weekday by use of the + key. Press and release the SET key to enter the mode "12/24 Hours Time Display Setting". 12/24 HOURS TIME DISPLAY SETTING 1. The "12h" or "24h" will start flashing in LCD1 (Default setting 12h). [. . . ] "--. -" appears in the outdoor temperature section of the LCD. 1) Remove the batteries of both units for one minute, then reinsert them again. Make sure the batteries are new and fresh. 2) Move the Atomic Clock closer to the transmitter or place the transmitter closer to the Skyscan Atomic Clock. [. . . ]
