3.Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.
4.Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference.
Note:
When the 915 MHz signal is received correctly, do not
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature sensor to the atomic clock (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).
CHANGING THE DISPLAY MODE (DAY, SECONDS, AND TEMPERATURES)
There are 4 possible display modes to view the day, seconds, and temperatures. The month&date/weekday/indoor temperature/outdoor temperature is the default.
To change the display:
1.Press the + key. The display should now show the month&date/weekday/seconds/outdoor temperature.
2.Press the + key a second time and the display will show the month&date/weekday/indoor temperature/seconds.
3.Press the + key a third time and the display will show the month&date/seconds/indoor temperature/outdoor temperature.
4.Press the + key a fourth time and the display will return to the normal display.
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the atomic clock. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic 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 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
•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
MOON PHASE
The Moon Phases, and their corresponding dates appear in LCD 2. There are 12 visible Moon Phases that will show in the LCD 2:
New Moon | Small Waxing | Large Waxing | First Quarter | Small Waxing | Large Waxing |
| Crescent | Crescent |
| Gibbous | Gibbous |
FullMoon | Large Waning | Small Waning | Last Quarter | Large Waning | Small Waning |
