Signal Interference
In some cases, the signal is affected by weather conditions and electrical
interferences, or the location of the clock itself may result in poor reception.
If the clock has not synchronized to the correct time within a few days of
activation, you may need to move the clock to a different location.
Frequently Asked Questions
Q. How long will the battery last?
A
.
A good AA alkaline battery will last over 12 months.
Q:
Is there a version of analog clock with more than the four
continental US times zones?
A:
La Crosse Technology
®
does not make an analog clock with more than
four time zones. These time zones are PT (Pacific Time), MT (Mountain
Time), CT (Central Time), and ET (Eastern Time).
Q:
Can I shut off the WWVB signal?
A:
No. If you manually set the time, when the clock receives a WWVB
signal, that signal will override the manual set.
Q:
Is there a booster antenna to receive the WWVB signal in a
difficult location?
A:
No, the clock cannot work with a booster antenna. Opening the clock or
movement voids the warranty.
Q:
Can I wire a control timing circuit to the La Crosse Technology
®
atomic clock?
A:
No, the clock cannot work on a timing circuit. Opening the clock voids
the warranty.
Q: Why do the hands spin?
A:
When the hands spin about the same time every day the clock is auto-
correcting the time. The hour hand should not spin more than twice around
the clock.
A:
Hands may spin if the battery is under powered or over powered. Use
only Alkaline batteries in the clock.
Troubleshooting
The wonderful advantage of owning a radio-controlled clock is that it is virtually
trouble free. If the clock receives a clear time signal, it will set itself perfectly. If
it does not receive a time signal, consider the following:
Battery:
The clock must have a fresh Alkaline battery to receive and
process the time signal.
Location:
Try a different location, ideally near a window. Your clock should
be at least six feet from computers, TVs, air conditioners, other radio-
controlled clocks and other electrical appliances that cause interference.
