GETTING STARTED:
BATTERIES INSTALLATION
1. Open the battery compartment cover.
2. Insert 2 "AA" batteries observing the polarity (+) and (-) as indicated.
3. Replace the battery compartment cover.

QUICK SET UP:
1. Once the batteries are in place, all segments of the LCD will light up. Then the indoor
temperature, the time as 12:00, the date as 1.1. , and calendar will be displayed.
IMPORTANT: If the indoor temperature is not displayed after a few seconds, remove
the batteries and wait for at least 30 seconds before reinserting them.
2. The clock automatically will begin to search for the WWVB time signal. After the icon
stops flashing on the display (approximately 5 minutes), you can set the time zone. You
can stop this auto reception by pressing the MONTH/HOUR/WAVE button. The default
time zone is Pacific Standard Time (PST). If you live in the Pacific Time zone move to
step 4.
3. To set the time zone:
Slide the SETTING switch to Time.
Press the ALM/ZONE/DST function button for 2 seconds to change the time
zone setting to the desired time zone.
EST (Eastern Time Zone)
CST (Central Time Zone)
MST (Mountain Time Zone)
Once the desired time zone is displayed in the panel, slide the switch to the lock position.
4. The WWVB time code reception will automatically start when the clock is powered
up. It will automatically set itself to the exact time and date after receipt of the WWVB
time code reception. This typically takes over night. For best reception place your clock
next to a window facing Colorado over night. Once a successful reception is received
relocate your clock to your desired location.

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 batteries are placed in the battery compartment, the WWVB tower icon in the
clock display will start flashing in the 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 static and a Wave OK icon will appear on the display.
If the tower icon flashes, but does not set the time and date, 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 (2meters).
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 Alarm 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: WAVEOK Icon-indicates positive WWVB reception. If the Atomic Alarm 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 previous procedures in "Setting up" the manual setting modes
can be entered. The following settings can now be programmed:
Time zone setting
DST ON/OFF
Manual time setting
Year setting thru 2050
Month setting
Date setting
12/24 hour time display setting
During reception attempts the WWVB tower icon will flash.
WWVB time reception takes place at 1:00 AM, 2:00 AM, 3:00 AM, and ends at 4:00PM
each day (attempts WWVB reception every full hour within this time frame). The other
times WWVB reception takes place are upon setup and after pressing the
Month/Hour/Wave button for 2 seconds Reception is generally not possible during
daylight hours due to the interference of the sun.
DST SETTING (daylight saving time)
Press and hold "Alarm/ZONE/DST" button for 2 seconds to select the DST function. The
DST icon right of the tower indicates that this function is ON.
Note: The DST default is "ON", meaning that the WWVB will automatically change the
time according to Daylight Saving Time in the Spring and Fall. For areas that do not
recognize DST changes (Arizona and parts of Indiana) turn the DST "OFF". All other
areas DST needs to be ON.
12/24 HOURS TIME DISPLAY SETTING
Press "DATE/MIN/12/24" button for 2 seconds to choose 12 or 24 Hr display format.
°C OR °F TEMPERATURE SETTING
Press "YEAR/SEC/°C/°F " button for 2 seconds to choose Celsius or Fahrenheit format
for temperature. This model will update the indoor temperature every
minute.

SNOOZE/LIGHT SETTING
The snooze can only be activated during alarm time for a snooze duration of 5 minutes by
pressing the top snooze bar.
Press "SNOOZE/LIGHT" button at any time to turn on the display light and it will last
for 5 seconds
