• Indicative of non-receipt of WWVB signal
• Electrical storms between you and Colorado can interfere with the WWVB signal
• Replace battery and perform restart procedure. Allow up to 5 days to receive a
signal.
• Reposition the atomic clock with the front or back facing Colorado.
• Try a different location, ideally near a window. The clock should be at least six feet
from computers, TVs, air conditioners, other atomic clocks and other electrical
appliances that cause interference.
• Large buildings, metal roofed buildings and buildings or rooms full of electrical
and/or radio equipment make it difficult to receive the WWVB time signal.
CLOCK IS INCORRECT BY HOURS BUT MINUTES ARE CORRECT
• This is a Time Zone issue. Hold your Time Zone button for 5 seconds. The clock
should correct itself.
• Check that DST is on. Use the selector bar to choose DST ON or OFF.
DAYLIGHT SAVING TIME
• Dependent on your location, position of the clock in your home, and atmospheric
interference, it may take up to 5 nights for the change from Daylight Savings Time to
Standard Time and vice-versa to occur.
• Press the DST indicator once. If the indicator is OFF the clock will not change.
(Default is ON).
• Check for fresh batteries. Without proper batteries, the antenna will have a harder
time picking up the signal.
• Position the atomic clock in a window (with the front or back) facing Ft. Collins,
Colorado and leave for up to five nights. If you do not have a window facing this
direction, position the clock near an outside wall and point the unit in this general
direction.
MANUALLY SET TIME
Note: Allow up to five nights for the clock to receive the WWVB signal before manually
setting the time.
Set the clock manually:
1. Hold the SET button for 3+ seconds to activate the manual mode. Once the clock is
in manual mode, there are two ways to move the minute hand forward.
2. Hold the SET button down to move the minute hand forward consistently.
3. Alternatively, press and release the SET button rapidly (more than once per second)
to move the minute hand forward step by step (in minute increments).
4. Use these features to move the minute hand forward until the correct time is set.
The clock will automatically leave manual mode after the SET button is not pressed
for 6+ seconds.
