antenna in the Wireless Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The Wireless Weather Station 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 continually measure every second of every day to an accuracy of ten billionths of a second a day. These physicists have created an inter

DETAILED SET-UP GUIDE I. BATTERY INSTALLATION (When one temperature sensor is being used) 1. First, insert the batteries to the temperature sensor (see “A. Remote Temperature Sensor” below). 2. Within 2 minutes of powering up the sensor, insert the batteries to the Weather Station (see “B. Wireless Weather Station” below). Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and humidity, and the time as 12:00 will be dis

Sensor signal reception icon* * When the signal is successfully received by the Weather Station, the icon will be switched on. (If not successful, the icon will not be shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is being done now. • If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the frequency is chan

4. The time and date can be manually set. Once the signal is captured, it will override any time and date set to the time zone selected. 5. Once the time and date are set, the Wireless Weather Station will conduct a search every night at midnight and correct to the accurate time and date (Daylight Saving Time is automatic). If the signal has been received in the past 24 hours, the reception indicator will be displayed. After a successful reception, no more reception attempt would be made

FEATURES AND OPERATIONS A. Minimum and Maximum Temperature and Humidity 1. Indoor Minimum and Maximum Temperature and Humidity The indoor weather station automatically stores the minimum and maximum indoor temperature and humidity. The minimum and maximum values are updated automatically when a new minimum or maximum is recorded, or until manually reset. a. From the normal display mode, press and release the “IN” key once to view the indoor maximum temperature and humidity
