INSTRUCTION MANUAL
With Wireless Outdoor and Indoor Temperature
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 (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:

Getting Started
Batteries Installation
Batteries installation of the clock
-Open the battery cover of the main unit.
- Insert 2 "AA" 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
replacement.
Batteries installation of wireless transmitter
-Open the battery compartment door.
- Insert 2 "C" size batteries in proper polarity (+) and (-) as indicated.
- Close the battery door.
~The low battery icon will show in the wireless transmitter LCD when your batteries need
replacement.
Warning: Do not mix old and new batteries.
Do not mix alkaline, standard (carbon—zinc), or rechargeable (nickel cadmium)
batteries.
The low battery icon in the outdoor temperature window of the clock indicates low battery
condition ol the wireless transmitter.
Atomic clock with wireless outdoor temperature consists of the clock and a wireless
temperature transmitter.
To ensure proper functioning of your 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 clock to your time zone:
PST = Pacific Standard Time
MST = Mountain Standard Time
CST = Central Standard Time
EST = Eastern 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
pans of Indiana) slide the DST switch to off.
Do not touch any other buttons or settings on you clock. It will automatically receive the
remote temperature and set your clock to the exact time, day, date and indoor
temperature.
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.
It 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.
The RF Temperature signal indicator in the clocks outdoor temperature window will show the
following:
— NO SIGNAL DETECTION

SIGNAL DETECTION
“ SUCCESSFUL RECEPTION
Atomic Clock Reception
Your atomic clock receives the offical US time signal from the US Atomic clock in Ft. Collins,
Colorado.SuccessfuI 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 3 hours. 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 may affect batten! life.
Interference
Signals from other household devices, such as entry controls, door bells and home security
systems, may temporarily interfere the Atomic Clock and cause reception failure. This is normal
and does not affect the general performance of the product. The transmission and reception of
temperature reading will resume once the interference has stopped.
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 3 hours 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 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 12HFt/24HR button to choose the desired display format. "AM"and I‘PM" display
only in the 12HFt format.
5. Press the C/F button to choose the Centigrade or Fahrenheit scale. 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.
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 clock. The clock will attempt outdoor
temperature reception for another 6 minutes and reinitiate synchronization with the wireless
transmitter. If the remote temperature cannot be received, check:
1.The distance of the Atomic Clock or Wireless Transmitter should be at least 3—4 feet 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 operation on the 433MHz signal frequency can also cause
interference.
Note: When the 433MHz signal is received correctly, do not re-open the battery cover of either the
wireless transmitter or the clock, as the batteries may spring free from the contacts and force a
false reset. Should this happen accidentally then reset both units (see Getting Started above)
otherwise transmission problems may occur.
The maximum transmission range is 100 feet from the wireless transmitter to the atomic clock (in
open space). However, this depends on the surrounding environment and interference levels. If
no receipt is possible despite the observation of these factors, all system units have to be reset
(see Getting Started).
Wall Mounting or Using the Stand
The main unit has a built in stand you can flip open to support the main unit on a flat surface. You
can close the flip 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
Atomic Clock down to make it secure.
The remote unit comes with a wall mount holder which can hold the unit on wall
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.
~ Press the "Reset" button on the wireless transmitter if the readout is irrelevant or does not
respond.
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.
