Instruction Manual
THE SKYSCAN ATOMIC CLOCK
With the SkyScan 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 (WWVB, 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:
http://www.boulder.nist.gov/timefreq/

Environmental Reception effects:
The SkyScan 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.
Near electrical appliances.
Near computers and televisions.
Bad weather locally or electrical storms between you and Colorado.
Inside moving vehicles.
Nearby metallic structures.
This clock receives a radio wave much like a TV or radio. Be sure to locate it near a
window or some other location where reception is good
Synchronization signal reception can be received in the Continental USA only. In other
areas, you can still use this clock by making time settings manually.
Features
Receives 60kHz WWVB signal.
Automatic time and date adjustment after signal reception.
Calendar with day of the week display from January 1,2000 to December 31,
2099.
Hour, minute and second display.
12 or 24-hour format.
Time accuracy (U.S. Atomic clock): better than 1 second in 3,000 years.
Time accuracy (free run): +/- 30 seconds per month.
Centigrade or Fahrenheit readout.
Battery life: approximate 1 year with alkaline batteries (not included).
Clock operating temperature from 0°C to 50°C (32°F to 122°F).
Indoor Temperature measuring range from -50°C to 70°C (-58°F to 158°F)
Temperature resolution 0.1 °C.

GETTING STARTED
Batteries Installation
Batteries installation of the clock
Insert new batteries into clock.
Insert 3 "C" batteries in polarity (+) and (-) as indicated.
Close the battery cover.
The low battery icon will show in the indoor temperature window when your
batteries need replacing.
Warning: Do not mix old and new batteries.
Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel
cadmium) batteries.
To ensure proper functioning of your SkyScan Atomic clock, please follow this power up
procedure:
1. Insert new batteries into clock.
2. 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 = Eastern Standard Time
3. 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 set
itself to the exact time, day, date and indoor temperature after receipt of the Atomic
Signal.

Atomic Clock Reception
Your SkyScan Atomic Clock receives the official US time signal from the US Atomic
clock in Ft. Collins, Colorado. Successful reception will activate the WAVE OK icon. If
the clock fails to receive the "WAVE" signal in the first reception sequence after power
up, it will repeat a 10-minute reception sequence every hour. This operation stops once
the WAVE is received. The clock automatically 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 will diminish the battery life.
Interference
Signals from other household devices, such as entry controls, door bells and home
security systems, may temporarily interfere with the SkyScan Atomic Clock and cause
reception failure. This is normal and does not affect the general performance of the
product.
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 hour 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 SkyScan 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 these easy steps:
1. 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.
3. Slide the Switch to the LOCK Position.
4. Press the l2HR/24HR button to choose the desired display format. "AM" and
"PM" display only in the l2HR format.
5. Press the °CIOF button to choose the Centigrade or Fahrenheit scale. The
indoor temperature will display in the chosen scale.

Wall Mounting or Using the Stand
The clock unit has a built in stand you can flip open to support the unit on a flat surface.
You can also close the stand and mount the unit on a wall. Drive a 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 SkyScan Atomic Clock down to make it secure.
Trouble - Shooting
Press the "Reset" button when the clock is displaying irrelevant time even when
the tower icon shows. This 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 3 new "C" alkaline batteries (not included)
Do not mix standard or rechargeable batteries
Do not mix new and old batteries
When the low battery icon appears on the display, replace the batteries with
appropriate ones.
