TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The transmitter uses 2 x AA,1.5V batteries. To install and replace the batteries, please follow the steps
below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery cover on the unit.
SETTING UP: Do not set the clock until the outdoor temperature is displayed.
1. Slide the battery cover open on the SkyScan Atomic Clock as indicated above (see "To install and replace
batteries in the Atomic Clock“ above).
2. Checking the correct polarization, insert 2 x AA, 1.5V batteries into the battery compartment and replace the
battery cover.
3. Once the batteries are in place, all segments of the LCD will light up briefly. Then the indoor temperature, the
time as -:--, the date as 1.1. , and weekday will be displayed.
IMPORTANT: If the indoor temperature is not displayed after a few seconds, remove the batteries and wait for
at least 10 seconds before reinserting them.
4. Within 2 minutes of activating the SkyScan Atomic Clock, place the batteries into the transmitter (see “To install
and replace batteries in the Temperature Transmitter” above).
5. After a few seconds of inserting the batteries into the transmitter, the Atomic Clock will start receiving data from
the transmitter. The remote temperature will then be displayed on the SkyScan Atomic Clock.
IMPORTANT: if this does not happen after 4 minutes, the batteries will need to be removed from both units and
reset from step 1. Remove the batteries and wait for at least 30 seconds before reinserting them.
6. After the clock receives the outdoor temperature, set your time zone using the manual settings below. The
default time zone is Eastern Standard Time.
7. After the clock receives the outdoor temperature the WWVB time code reception will automatically start. This
reception typically takes between 5-10 minutes in good conditions. If after 10 minutes the WWVB time has not
been received, use the SET key to manually enter the set mode and change either the time or date in order to
activate the WWVB reception (see manual settings below). The clock will then automatically attempt to receive
the WWVB time from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour within
this time frame). When this is successful, the received time will override the manually set time. The date is also
updated with the received time (Please refer to notes on “Radio controlled time” and “Manual time setting”).
Note:
In the event of changing batteries of the unit ensure that the batteries do not spring free from the contacts. Always
wait at least 30 seconds after removing the batteries before reinserting, otherwise start up and transmission problems
may occur.

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 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)

MANUAL SETTINGS
Note:
If the Atomic Clock has already successfully received the WWVB time signal and displays the correct time
and date, then the Manual settings can be omitted.
After completion of the above described procedures in “Setting up” the manual setting modes can be entered by
pressing the SET key. The following settings can now be programmed:

 -9 ALA (Alaska time),
 -10 HAW (Hawaii time).
 "GMT” will be displayed if set to GMT (0).
2. Press the SET key to enter the “DST Setting“.
DST SETTING (daylight saving time)
1. The ON digit will start flashing on LCD1. Set the DST ON or OFF by pressing the + key.
2. Press the SET key to enter the “Language Setting“.
Note:
The DST default is “ON”, meaning that the WWVB will automatically change the time according to Daylight
Saving Time in the spring and fall. For areas that do not recognize DST changes (Arizona and parts of Indiana) turn
the DST “OFF”.
LANGUAGE SETTING
The weekdays can be displayed in LCD1 with the pre-set languages: US English, French and Spanish.
1. Set the desired language for the weekday display in LCD 2 by use of the + key.
2. Press the SET key to enter the mode “Manual Time Setting”.

MANUAL TIME SETTING
In case the SkyScan Atomic Clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.),
the time can be manually set. The clock will then work as a normal Quartz clock.
Note:
In 12 hours mode the time will be displayed with an additional “PM” for the time from 12:00 noon until 11:59.
1. The hour digits will start flashing on LCD1. Set the desired hours by pressing the + key followed by pressing the
SET key.
2. Now the minute digits will start flashing. Set the desired minutes by pressing the + key . If the + key is held, the
units will increase by 5.
3. Press the SET key to move to the “Year Setting”.
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 the 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.
YEAR SETTING
The year can be selected sequentially from 2000 to 2049 and will then start over again (default setting 2000). Only
the last 2 digits of the year will be visible on LCD2.

OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the SkyScan 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 minutes. 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.
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 Skyscan
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).
POSITIONING
Note:
Before permanently mounting ensure that the Skyscan 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. 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.

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 STANDS
The foldout table stand legs are located on the backside, at the lower corners, and on both sides of the
battery cover. The hinges are towards the edges of the SkyScan Atomic Clock, and the ends (with no hinge)
need to be folded out towards the edge. Once the foldout table stands are extended, place the Atomic Clock
in an appropriate location.
WALL MOUNTING
1)

Using a straightedge, horizontally space at 3-15/16 of an inch (100.58mm) three screw positions on a
wall.
Install three mounting screws (not included) into a wall within transmission range—leaving
approximately 3/16 of an inch (5mm) extended from the wall.
Place the SkyScan Atomic Clock onto the screws, using the hanging holes on the backside. Gently
pull the Atomic Clock down to lock the screws into place.
Always ensure that the SkyScan Atomic Clock locks onto the screws before releasing.

4)

Remove the mounting bracket from the Outdoor Temperature Transmitter.
Place the mounting bracket over the desired location. Through the three screw holes of the
bracket, mark the mounting surface with a pencil.
3)
Where marked, start the screw holes into mounting surface.
Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the bracket.

MOUNTING WITH ADHESIVE TAPE
1) With a nonabrasive solution, clean and dry the back of the mounting bracket and the mounting
surface to ensure a secure hold. The mounting surface should be smooth and flat.
2) Remove the protective strip from one side of the tape. Adhere the tape to the designated area on
the back of the mounting bracket.
3) Remove the protective strip from the other side of the tape. Position the Outdoor Temperature
transmitter in the desired location, ensuring that the Skyscan Atomic Clock can receive the signal.
