About the Atomic Clock
The National Institute of Standard and Technology (NIST) in Fort Collins, Colorado broadcasts the time
signal (WWVB at 60 kHz AM radio signal) with an accuracy of 1 second per every 3,000 years. The signal
is able to cover a distance of up to 2,000 miles from the source. Like a typical AM radio, your atomic
clock will not be able to receive the WWVB signal in places surrounded by heavy concrete or metal
panels. The reception of the time signal is also greatly affected by electrical or electronic interference.
To get the best performance from the atomic clock, install the clock nearer to a window facing west.
Battery Installation and Set Up
Remove the battery cover and insert 2 “AA” alkaline batteries according to the direction shown inside
the battery compartment. Once the batteries are installed the display will show all segments of the LCD
display for 3 seconds and will beep once. Then the display will show 12:00pm Jan 1, 2000 together with
room temperature. The Time Zone is defaulted at PST – Pacific Standard Time.
Select the correct Timer Zone
1. Press the ZONE / DST button to select PST, MST, CST or EST.
2. Once a time zone is selected, your Atomix clock will start searching for the time signal.
3. While your Atomix clock is seeking the signal, the signal strength icon will change
gradually indicating the search is continuing.
4. If the signal is available, your Atomix clock will display the local time in about 3-5
minutes. The tower icon and “OK” will appear on your display.
5. If the signal is not available when you are setting the clock functions, enter the present
time and calendar by holding the CLK / CAL button for 3 seconds and then press and
release the + or – buttons to select the correct values.
6. When the clock is searching for the signal and the tower icon on the LCD display is
flashing, the manual set buttons will not function. To stop the clock from searching for
the signal, press the + button on the back of the clock. This will allow you to set the
balance of the features manually. When you have set other features, press the + button
again to resume the search for the time signal.
