INITIAL SET UP
Install batteries: Install batteries into the sensor first.
x
The sensor uses 2 x AA, batteries (IEC LR6, 1.5V). To install and replace
the batteries, please follow the steps below:
x
Remove the battery cover from the back of the sensor.
x
Insert the batteries, observing the correct polarity inside battery
compartment.
x
Replace the battery cover on the unit.
Next install batteries into the clock.
x
The Atomic Clock uses 2 x AA batteries (IEC LR6, 1.5V).
x
Insert batteries into the Wall Clock, observing the correct
polarity (see markings inside battery compartment).
x
Replace the battery cover.
x
Manually Set Time and Date or wait for WWVB signal.
NOTE: Default Time Zone is Eastern.
Alkaline batteries are recommended for use in both units. Avoid using rechargeable
batteries. Do Not Mix Old and New Batteries. Do Not Mix Alkaline, Standard, or
Rechargeable Batteries.
3
Allow the sensor and the clock to sit 5-10 feet apart for 15 minutes after installing batteries to lock
in the Temperature signal. After 15 minutes mount the sensor outside.
NOTE:
After the sensor and clock have been operating for awhile, if the temperature signal goes to
dashes, bring the sensor in the house, remove batteries from the sensor and the clock for 15
minutes and set up again.
915MHZ RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The radio-controlled 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.
The distance of the radio-controlled clock or outdoor temperature transmitter should be at
least 6 feet (2 meters) away from any interfering sources such as computer monitors,
cordless phones or TV sets.
2.
Avoid placing the receiver 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 (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 re-open the battery cover of either the
outdoor temperature transmitter or radio-controlled clock, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then remove batteries for all
units for 15 minutes, otherwise transmission problems may occur. Follow Initial Set-up.
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
4
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:
x
Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 6 feet (2 meters).
x
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.
x
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 SET TIME).
SET TIME
Hold SET button for 5 seconds, to enter the time set mode.
x
TIME ZONE (GMT +12 to –12): The Time Zone will flash a number following by the letter h.
Use the PLUS to change the Time Zone. North American Time Zones are negative
numbers and will show letters: -4h ATL, -5h EST, -6h CST, -7h MST, -8h PST, -9h ALA and
-10h HAW. Press and release the SET button once.
x
DAYLIGHT SAVING TIME: DST will show ON or OFF flashing. Most states observe DST,
so this should be set to ON. However if your location does not observe DST, use the PLUS
button to turn it OFF. Press and release the SET button once.
x
LANGUAGE: Select from US (English), F (French), E (Spanish), or d (Deutsch). The day
of the week will display in the selected Language.
x
HOUR: The Hour will flash. Use the PLUS button to set the Hour. If using 12-hour Time
Mode, be sure to set the Hour for am or pm. Press and release the SET button once.
