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”).

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:
•Time zone setting
•DST ON/OFF
•Language display setting
•Manual time 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.

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
Alarm icon
(((•))) (ON)

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.
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 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.
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.
MOUNTING WITH SCREWS
1) Remove the mounting bracket
from the Outdoor Temperature
Transmitter.
2) 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.
4) 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.
TROUBLESHOOTING
Problem:
The LCD is faint.
Solution:
1) Replace the batteries.
Problem:
No reception of WWVB signal
Solution:
1) It may help reception to face
the front of the Atomic Clock
in the general direction of Ft.
Collins, Colorado.
2) Wait overnight for signal.
3) Be sure the Skyscan Atomic
Clock is at least 6 feet (2
meters) from any electrical
devices, i.e. TV sets,
computers, or other radio
controlled clocks.
4) Remove batteries for five
minutes, reinsert and leave
the unit alone overnight
without pressing any keys.
Problem:
Hour is incorrect (minute and
date are correct).
Solution:
1) Be sure the correct time zone
and daylight saving time are
selected.
Problem:
"OFL“ appears in the indoor
temperature section of the LCD
Solution:
1) Move the Skyscan Atomic
Clock to an area with
warmer or cooler
surrounding temperature.
Current surrounding
temperatures are outside
measuring range.
Problem:
"--.-" appears in the outdoor
temperature section of the LCD.
Solution:
1) Remove the batteries of both
units for one minute, then
reinsert them again. Make
sure the batteries are new
and fresh.
2) Move the Atomic Clock closer
to the transmitter or place the
transmitter closer to the
Skyscan Atomic Clock. Make
sure the clock is at a
receivable range from the
transmitter.
3) Move the units to another
location. Interferences from
other electrical devices
operating on the same signal
frequency (433MHz) may
prevent correct signal
transmission and reception.
Problem:
"OFL“ appears in the outdoor
temperature section of the LCD.
Solution:
1) Wait until the current
surrounding temperature
cools down or increases.
Current temperature is
outside of the measuring
range of the transmitter. The
outdoor temperature will be
displayed again once the
current surrounding
temperature is within the
range of the transmitter.
CARE AND MAINTENANCE:
•Avoid placing the units in areas prone to vibration
and shock as these may cause damage.
•Avoid areas where the units can be exposed to
sudden changes in temperature, i.e. direct sunlight,
extreme cold and wet/moist conditions as these will
lead to rapid changes which reduces the accuracy of
readings.
•When cleaning the LCD and casing, use a soft damp
cloth only. Do not use solvents or scouring agents.
•Do not submerge the units into water.
•Immediately remove all low powered batteries to
avoid leakage and damage. Replace only with new
batteries of the recommended size.
