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.
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.
HOW LONG WILL THE BATTERY LAST?
A good AA Alkaline battery will last over 12 months.
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.
Opening the clock or movement voids the warranty.
CAN I WIRE A CONTROL TIMING CIRCUIT TO THE LA CROSSE
TECHNOLOGY
®
ATOMIC CLOCK?
No, the clock cannot work on a timing circuit.
