[. . . ] WS-8349U ATOMIC CLOCK WITH INDOOR TEMP/HUMIDITY AND OUTDOOR TEMPERATURE Instruction Manual FEATURES: ATOMIC CLOCK: Hanging holes LCD1 display Function keys Battery cover LCD2 display Foldable stand · · · · · · · · · · · WWVB Radio controlled time with manual time setting Time display: hour, minute, second Alarm setting with snooze function Complete calendar display Weekday display (3 languages to choose from: English, French and Spanish) Time zone setting Daylight saving time ON/OFF option (DST) Indoor temperature and humidity display Outdoor temperature display via 433MHz transmission Wall mount or freestanding Weather forecast with weather tendency indicator 1 OUTDOOR TEMPERATURE TRANSMITTER: · Mounting Bracket · Remote transmission of outdoor temperature to the atomic clock by 433 MHz signals Wall mounting case TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER The transmitter uses 2 x AA, 1. 5V batteries. To install and replace the batteries, please follow the steps below: 1. Insert the batteries, observing the correct polarity (see marking inside battery compartment). Alkaline batteries are recommended for use in both units. [. . . ] Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause interference. 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). WEATHER FORECAST 12 The weather forecasting feature is estimated to be 75% accurate. The weather forecast is based solely upon the change of air pressure over time. The WS-8349U averages past air-pressure readings to provide an accurate forecast, creating a necessity to disregard all weather forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another (i. e. from one floor of a building to another floor). In areas where the weather is not affected by the change of air pressure, this feature will be less accurate. Weather Icons There are 3 possible weather icons that will be displayed in the LCD 2: Sunny--indicates that the weather is expected to improve (not that the weather will be sunny). Sun with Clouds--indicates that the weather is expected to be fair (not that the weather will be sunny with clouds). Clouds with Rain--indicates that the weather is expected to get worse (not that the weather will be rainy). The weather icons change when the unit detects a change in air pressure. The icons change in order, from "sunny" to "partly sunny" to "cloudy" or the reverse.
