OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the atomic clock every 4 seconds. The atomic clock will update the temperature display every 20 seconds.
The range of the outdoor temperature transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitter. Also the batteries may be reduced in power during periods of extreme cold temperatures.
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The atomic clock will receive the temperature data within 4 seconds. If the temperature data is not being received 2 minutes after setting up (or the display shows “- - -”), then please check
the following points:
1.
2.
The distance of the atomic clock or outdoor temperature transmitter should be at least 6 feet (2 meters) away from any interfering sources such as computer monitors or TV sets.
Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3.
4.
Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.
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 re-open the battery cover of either the outdoor temperature transmitter or atomic clock, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature transmitter 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 four possible display modes to view the day, seconds, and temperatures.
The indoor temperature/outdoor temperature/ month&date/weekday is the default.
To change the display:
1.
2.
3.
4.
Press the + key. The display should now show the seconds/outdoor temperature/ month&date/weekday.
Press the + key a second time and the display will now show the indoor temperature/seconds/ month&date/weekday.
Press the + key third time and the display will now show the indoor temperature/outdoor temperature/month&date/seconds
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.
After 15 minutes the WWVB tower icon in the clock display will start flashing in the top center of the lcd. This indicates 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).
MOON PHASES SYMBOLS:
The Moon Phases and their corresponding dates appear in LCD 2. There are 12 visible Moon Phases that will show in the LCD 2.

POSITIONING
Before permanently mounting ensure that the atomic clock is able to receive WWVB signals from the desired location. Also, extreme and sudden changes in temperature will decrease the
accuracy of the atomic clock, and changes in elevation will result with inaccurate temperatures readings for the next 12 to 24 hours. These changes will require a 12 to 24 hour wait before
obtaining reliable data.

To achieve a true temperature reading, avoid mounting where direct sunlight can reach the outdoor temperature transmitter. It is recommended to mount the outdoor temperature
transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range is 330 feet (100 meters) obstacles such as walls, concrete, and large metal objects can
reduce the range.
Place both units in their desired location, and wait approximately 10 minutes before permanently mounting to ensure that there is proper reception. The outdoor temperature transmitter is
not waterproof and should not be placed anywhere it will become submerged in water or be directly in the rain.
POSITIONING THE ATOMIC CLOCK:
There are two possible ways to mount the atomic clock:
•
•
use of the foldout table stand, or
wall mounting
FOLDOUT TABLE STAND
The foldout table stand leg is located on the backside. Pull the stand out from the bottom center edge of the atomic clock, below the battery
compartment. Once the foldout table stand is extended, place the atomic clock in an appropriate location.
WALL MOUNTING
1) Using a straightedge, horizontally space at 2-3/4 of an inch (70 mm) three screw positions on a wall.
2) Install three mounting screws (not included) into a wall within transmission range—leaving approximately 3/16 of an inch (5mm)
extended from the wall.
3) Place the atomic clock onto the screws, using the hanging holes on the backside. Gently pull the atomic clock down to lock the screws into place.
Note:
Always ensure
that the atomic clock locks onto the screws before releasing.
