Note:

The unit will still try and receive the signal every day despite it being manually set. When it does
receive the signal, it will change the manually set time into the received time. During reception
attempts the WWVB tower icon will flash. If reception has been unsuccessful, then the WWVB
tower icon will not appear but reception will still be attempted the following hour.

WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB
reception every full hour within this time frame). When the time signal is received for example at
1:00 am, the Skyscan Atomic Clock will not attempt to receive the WWVB signal for th e
remaining hours until 6:00 am. Therefore, the next signal attempt will take place between 12:00
am and 6:00 am the next day. The other times WWVB reception takes place, are upon setup and
after manual time set exiting mode. Reception is generally not possible during daylight hours due
to the interference of the sun.

OUTDOOR TEMPERATURE TRANSMITTER:

The temperature is measured and transmitted to the Atomic Clock every 1 minute. The Atomic
Clock will update the temperature display every 5 minutes.
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.

433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER

The Atomic Clock will receive the temperature data within 4 min utes. If the temperature data is
not being received 4 minutes after setting up (the display shows
“- - -”), then please check the following points:

1. 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.

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 (433MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause
interference.

larm icon

(((•))) (ON)

Note:
When the 433 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 82 feet (25 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 three 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 now show the month&date/seconds/indoor
temperature/outdoor temperature.

3. Press the + key third 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 clo ck h as
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)

POSITIONING

Note:

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 OutdoorTemperature 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 82 feet (25 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 stands, 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

Note:

Always ensure that the Atomic Clock locks onto the screws before releasing.

POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER

The Outdoor Temperature transmitter can be mounted in two ways:

• with the use of screws, or using the adhesive tape.

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.
