It can receive the time signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3 atomic clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts the time signal (WWVB, 60kHz) continuously from Fort Collins, Colorado. This signal can be received anywhere in the continental USA that long wave (AM) radio reception is possible with a portable radio. It is expected that the signal can cover a distance of over 2,000 miles from the transmitter. Therefore, your clock will receive the signal within the broadcast range anywhere an AM signal can be received; generally the signal cannot be picked up in massive metal and concrete structures unless near a window. In addition, some environmental effects (see next page) may affect the transmitting distance. For more information, please study the WWVB WEB page of NIST at: http://www.boulder.nist.gov/timefreq/ NH Fort Collins Feature VT WA ND MT ID MI WY NV UT 1200 miles CO CA AZ 2000 miles IA NE IL KS OK NM PA OH IN WV VA KY MO CT NJ DE MD RI NC TN SC AR MS TX MA NY WI SD ¥ Receive 60kHz WWVB signal transmitted by NIST in Fort Collins,Colorado. ¥ Automatic time adjustment after signal reception. ¥ Calendar with day of the week display from Pacific January 1, 2003 to December 31, 2039 Standard Time Mountain ¥ Hour, minute and second display Standard Time ¥ 12 or 24-hour format ¥ Indoor temperature and remote temperature ¥ Indoor humidity and remote humidity ¥ Centigrade or Fahrenheit readout ¥ Clock operating temperature from 0ûC to 50ûC ( 32ûF to 122ûF ) ¥ Indoor, Outdoor Temperature measuring range from -50ûC to 70ûC (-58ûF to 158ûF )* ¥ Temperature resolution 0.1ûC ¥ humidity resolution 1% ¥ Time accuracy (Atomic clock): better then 1 second in 3000 years. ¥ Time accuracy (free run): average with in ±60 seconds per month ME MI MN OR AL GA LA FL Central Standard Time Eastern Standard Time * If using the wireless transmitter with temperature below 32ûF or above 122ûF, user are recommended to use Lithium battery to enhance batteries life.

Note that the outdoor temperature display on the main unit is dominated by the selection on the main unit. Whatever the display unit of the remote unit is, it will be automatically converted to the chosen one of the main unit. Check weather forecast ¥ The Weather Forecast is displayed in the weather forecast reading. There are five readings for the forecast: sunny, sunny & cloudy, cloudy, rainy and stormy. M0xx SIGNAL DETECTION SUCCESSFUL RECEPTION Losing Synchronization of the wireless thermometer If the main unit displayed a proper outdoor temperature & humidity in the past but now displays blank "-", the remote unit and main unit may have lost synchronization. If this occurs, press the RE-SYNC button of the main unit. The main unit will attempt outdoor temperature reception for another 6 minutes and reinitiate synchronization with the remote unit. If the outdoor temperature/humidity cannot be received, check: 1. The distance of the main unit or remote unit should be at least 3-4 feet away from any interfering sources such as computer monitors or TV sets. 2. Avoid placing the main unit onto or in the immediate proximity of metal window frames. 3. Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception. 4. Neighbors using electrical devices operation on the 433MHz signal frequency can also cause interference. Note: When the 433MHz signals is received correctly, do not re-open the battery cover of either the remote unit or the main unit, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset both unit (see Getting Started above) otherwise transmission problems may occur. The maximum transmission range is 100 feet from the remote unit to the main unit (in open space). However, this depends on the surrounding environment and interference levels. The temperature signal travels in a straight line from the remote unit to the main unit. The signal will not curve around blocking object. If no reception is possible despite the observation of these factors, all system units have to be reset (see Getting Started). Interference Signals from other household devices, such as entry controls, door bells and home security systems, may temporarily interfere with the units and cause reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature reading will resume once the interference has stopped.
