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 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.
• Immediately remove low powered battery to avoid leakage and replace with one fresh AA LR6
battery.
• Do not attempt to repair your alarm clock.
Battery Change
• It is recommended to replace the battery on an annual basis to ensure optimum accuracy or when
the battery icon indicates low running power.
• When replacing the battery, be sure to leave battery out for at least one minute to allow complete
reset.
• Place battery firmly in compartment to ensure proper contact.
