time set. If the time is manually set, be sure to set the time to the correct
AM/PM time.
Programming Mode

6) Temperature Selection: Press the MODE/+ key to select °F (Fahrenheit)
or °C (Celsius). Press the SET key. The programming mode is complete.
3) DST: Press the MODE/+ key to switch Daylight Savings Time off or on. The
WWVB automatically corrects for DST; “DST” is to be set to “OFF” only in
areas that do not follow DST. Press the SET key.

4) Exit this mode by pressing the SNOOZE bar or waiting for 15 seconds.
Ionosphere, reception is very limited during daylight hours. Your alarm 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. Your Radio Controlled Alarm Clock cannot receive signals from
other transmitters in the world (Germany’s DCF 77, Japan’s JG2AS, or
England’s MSF-60). Outside the United Sates, the alarm clock will keep time
as a precision quartz clock.
Alarm is activated when ((1)) or ((2)) is displayed to the right of the map. To
activate/deactivate an alarm, press the ALM1 or ALM2 key briefly.
Display Modes
Your alarm clock can be set to display (underneath the US map) either the
seconds, calendar, alarm 1 time, alarm 2 time or indoor temperature.
1) Press the MODE/+ key to change the display function.
2) The display will toggle through the options.
Troubleshooting
The Radio Controlled Alarm Clock is designed to be simple to operate yet
offer a complete range of features. Some common questions are listed below.
Q: I inserted a battery, but the time did not set; what’s wrong?
A: In many areas of the country a signal cannot be received during daylight
hours due to the interference of the sun. By leaving the clock alone, a
signal will be found during the night and the alarm clock will be set to the
General Information on 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 your alarm clock. However, due to the nature of the Earth’s
absolutely correct time and date by the next morning. When a signal is
received, the radio tower icon is displayed to the left of the US map. If no
signal is received, there will be no tower icon.
Q: After the clock set itself, why does it show the wrong hour?
A: The time zone is not set correctly. Look on the LCD map to see if the
proper time zone is highlighted. If not, follow the “Programming Mode”
section.
Q: Why hasn’t my alarm clock picked up a signal?
A: Short-term interference can be caused by storms between you and
Colorado during reception time. There is interference between the Alarm
Clock and the signal from Colorado. Be sure to keep the alarm clock at
least six feet from any electrical device (computers, television sets, other
radio-controlled clocks, etc.). Avoid placing alarm clock on metal surfaces.
The ideal location for signal reception is in a window facing Colorado.
Q: What does “DST ON/OFF” mean?
A: Some parts of the country do not follow Daylight Savings Time (Arizona
and parts of Indiana). Since the WWVB signal includes the correction for
this, these areas must have the DST OFF.
Care and Maintenance
Q: Can I set the time and date without waiting for a signal?
A: Yes; simply follow the “Programming Mode” directions.
•
•
Extreme temperatures, vibration and shock should be avoided as these
may cause damage to the unit and could give inaccurate readings.
Use a soft, dry cloth to clean alarm clock. Do not use solvents as they may
mark the LCD and case.
Do not expose alarm to water or high humidity.
Immediately remove low powered battery to avoid leakage and replace with
one fresh AA LR6 battery.
Q: How often does the alarm clock synchronize with the WWVB?
A: The Alarm Clock searches for a signal immediately after inserting a
battery. After an initial signal is received, the alarm searches for a signal
starting at 12:00 AM (midnight) every night and synchronizes at that time.
