TIME IS INCORRECT
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. Press and release the small, unmarked gray button
between the ET and CT button one time.
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.
HOW LONG WILL THE BATTERY LAST?
A good AA Alkaline battery will last over 12 months.
With 2 additional batteries, battery life is up to 3 years.
CAN I SHUT OFF THE WWVB SIGNAL?
No. If you manually set the time, when the clock receives a WWVB signal, that
signal will override the manual set.
IS THERE A BOOSTER ANTENNA TO RECEIVE THE WWVB SIGNAL IN A
DIFFICULT LOCATION?
No, the clock cannot work with a booster antenna.
