The ATOMIC Clock
With the Atomic Clock, you have the most accurate timepiece within the
continent. It can receive the time signal transmitted by the National
Institute of Standards and Technology (NIST). which is regulated by 3
atomic clocks and deviates less than 1 second within 3,000 years. The NIST
broadcasts the time signal (WW VB, 60kHz) continuously from Fort Collins,
Colorado. This signal can be received anywhere in the continental USA that long
wave (AM) radio reception is possible with a portable radio. It is expected
that the signal can cover a distance of over 2,000 miles from the transmitter.
Therefore, your clock will receive the signal within the broadcast range ‘
anywhere an AM signal can be received; generally the signal cannot be
picked up in massive metal and concrete structures unless near a window;
In addition, some environmental effects (see next page) may affect the
transmitting distance.
For more information, please study the WWVB WEB page of NIST at:

Environmental Reception effects:
The Atomic Clock obtains the accurate time with wireless technology Same as all wireless
devices, the receiving ability may be affected by, but not limited to, the following
circumstances:
Long Transmitting distance.
Nearby mountains and valleys,
Among tall buildings.
Near railway, high voltage cable. etc.
Near freeway, airport, etc.
Near construction site.
Inside concrete buildings. a,
Near electrical appliances.
Near computers and televisions.
Bad weather locally or electrical storms between you and Colorado.
inside moving vehicles.
Nearby metallic structures.
Location Precautions
This clock receives a radio wave much like a TV or radio. Be sure to locate it near a window or some
other locations where reception is good. Avoid the following Iocation.which can inlertere with proper
reception

Notes: Do not use old batteries or different batteries together.
Getting Started
“he SkyScan Atomic Clock with wireless outdoor temperature consists of the SkyScan Clock and a
wireless temperature transmitter.
To ensure proper functioning of your SkyScan Atomic clock with outdoor temperature, please follow this
power up procedure:
1. Insert new batteries into the main unit.
2. Insert batteries into the remote temperature transmitter.
3. Slide the time zone switch on the back of the SkyScan clock to your time zone:
PST = Pacific Standard Time
MST = Mountain Standard Time
CST = Central Standard Time
EST = Eastem Standard Time
4. Slide the daylight savings time switch (DST) to ON. This setting allows your clock to
automatically change from standard time to daylight savings time and back each spring and fall. If
you live in an area that does not recognize daylight savings time (Arizona and parts of Indiana)
slide the DST switch to off,
Do not touch any other buttons or settings on you SkyScan clock. It will automatically
receive the remote temperature and set your clock to the exact time, day, date and
indoor temperature and humidity.
Outdoor Temperature
Upon power up (or pressing the reset button) the temperature RF signal is immediately sent to the clock.
The clock attempts to receive the RF temperature signal for 5 minutes. The clock refreshes the RF
temperature every 3 minutes.
.P.6 1
If the RF temperature signal is not received within 5 minutes, blank ". . ." will appear in the outdoor
temperature window of the clock. In this case, press the TEMP FINDER button behind the flip over stand
of the clock. The clock will attempt outdoor temperature reception for another 6 minutes.
Try relocation the clock or the transmitter if the clock does not display the outdoor temperature after 6
minutes.

Atomic Clock Reception
Your SkyScan Atomic Clock receives a signal from the US Atomic clock in Ft. Collins, Colorado. ll" the
clock fails to receive the "WAVE” signal in the first reception sequence alter power up, it will repeat a
10-minute reception sequence every 30 minutes. This operation stops once the WAVE is received. The
automatically clock refreshes the WAVE each night,
You can start reception of the time signal anytime by pressing the TIME WAVE button.
Note: Frequent use of this feature may affect battery life,
Interference
Signals from other household devices, such as entry controls, door bells and home security systems, may
interfere the RF Thermo Clock to cause temporarily reception failure. This is henna] and does not affect
the general performance of the product. The transmission and reception ofteinpcraturc reading will
resume once the interference stopped.
Wall Mounting or Using the Stand
The main unit has a built in stand which can flipped open, it can support the main unit on a flat surface,
Or you can close the flip and mount the unit on wall. Drive the screw into the wall until the head extends
about 1/8 inch from the wall, then locate the keyhole slot over the screw head and slide the Atomic Clock
down to make it secure.
P.7
The remote unit comes with a wall mount holder which can hold the unit on wall
Manual clock setting
If 20 minutes after power up your clock has not successfully received the time signal, you may set the
clock manually or the clock will continue an automatic search each 30 minutes until the signal is
received. Best reception of the WAVE is during the nighttime when the atmosphere allows a stronger
signal to travel farther from the Colorado transmitter. It is strongly recommended that you allow the
SkyScnn Atomic clock one or two evenings to automatically catch the WAVE and set itself.
If you decide to manually set the clock make sure the time zone and DST switches are properly set (see
getting started). Then follow mese easy steps:
ll Slide the switch to TIME SET and the time will flash on the display. Press the HR and MIN
buttons until you reach the desired time.
2 Slide the switch to calendar and the year and date will flash on the display. Press the YEAR,
MONTH and DATE buttons until you reach the desired calendar setting.
. Slide the Switch to the LOCK Position.
. Press the 12HR/24HR button to choose the desired display format. "AM"and "PM" display only
in the lZHR format
5. Press the OP button to choose the Centi grade or Fahrenheit sealer Both the indoor and outdoor
temperature will display in the chosen scale. Note: the display on the remote unit can also show
Centigrade or Fahrenheit independent of the temperature scale chosen for the clock display.
Au
Losing Synchronization of the wireless thermometer and the clock:
If the clock displayed a proper outdoor temperature in the past but now displays blank ”--", the wireless
transmitter and clock may have lost synchronization If this occurs, press the TEMP FINDER button
behind the flip over stand of the eleck. The clock will attempt outdoor temperature reception for another
6 minutes and reinitiate synchronization with the wireless transmitter. lfthc remote temperature cannot
be received, check:
The remote unit is still in place.
The batteries of both units and replace if necessary.
The transmission is within range and possible interference accounted for.
Shorten the distance ifnecessary.

Muble - Shooting
' Press the "Reset" button when the clock is displaying irrelevant time even when the tower icon shows
on LCD. Ti‘llS may happen when the external noise is severe enough to interfere with the time signal.
Care of your clock
- Avoid exposing your clock to extreme temperatures, water or severe shock.
- Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents ,
- Do not subject the clock to excessive force, shock, dust, temperature or humidity, Any of these
conditions may shorten the life of the clock.
° Do not tamper with any of the internal components of this clock. This will invalidate the warranty and
may cause damage. > .
Correct usage of the batteries
' Use 2 new "AA" alkaline batteries (not included)
- Do not mix standard or rechargeable batteries
- Do not mix new and old batteries
~ When the low battery mark " m." appears on the display, replace both batteries with new ones.
Warranty
- This product is warranted to be free of defects in manufacturing for 90 days after purchase. Defective
clocks should be returned to the place of retail purchase. '
