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: 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: Can I set the time and date without waiting for a signal?
A: Yes; simply follow the “Programming Mode” directions.
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.
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: 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
• 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.
