the WWVB signal.
DST (Daylight Saving Time) ON/OFF:
The change to and from DST is based on an embedded bit in the WWVB signal that tells the clock when to change.
DST is defaulted to the ON position. The clock will make the adjustment to and from DST automatically when the
signal is received. It is not necessary to press the DST button to change to standard time.
In areas where no DST is observed deactivate DST by pressing the DSTOFF switch. Pressing DST-OFF during DST
the clock will switch to Standard Time. Press it again DST will be activated again. Pressing DST-OFF during ST the
clock will switch to DST.
Q-SET BUTTON:
In some cases, the La Crosse Technology clock may not receive the WWVB signal due to atmospheric disturbances
or hard to reach locations such as inside shopping malls. In this case, please use the Q-Set button, located at the
back of the clock to manually set the time.
SET TIME:
On rare occasions it is not possible to receive a WWVB signal at the location of the clock. In this instance the clock
may be set manually and will operate as a quartz clock.
1.
Press and hold the Q-Set Button on the backside of the movement until the second hand starts running.
2.
Release the button quickly (less than 3 seconds) and press it again to set actual time.
3.
Three seconds after releasing the Q-Set Button your clock will start working as a Quartz Clock.
4.
In Quartz Mode your clock will try to receive each even hour. If a signal is received it will override the manual
set time.
AUTO CORRECTION:
The clock automatically checks its hands position daily between 3:00 and 4:05 (pm). If hands position is not equal to
internal time, the hands are driven (quick run) to the correct time again. You will see the hands spin completely
around during this correction. This is normal behavior.
ADDITIONAL INFORMATION:
For a better understanding of how and why your clock works please continue reading.
The La Crosse Technology clock is designed for indoor use only. Select a location to place your radio controlled
clock where it will be at least six feet away from a TV, computer, air conditioner or other household electrical
appliances. The optimal location is near a window. Windows facing Colorado provide the best signal.
The WWVB time signal will easily penetrate masonry and wood framed buildings. WWVB will penetrate almost every
residential building and most steel buildings if they have adequate windows. It is not possible, however, for WWVB to
penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. In
buildings that WWVB cannot penetrate you may set the time using the manual time set button. When the clock
receives the WWVB signal it will automatically set the hands to the exact time.
La Crosse Technology clocks do not receive or process radio controlled time signals from Germany's DCF 77,
Japan's J Ga AS, or England's MSFs atomically regulated transmitters. La Crosse Technology clocks can be
manually set and used anywhere.

NOTHING IS MORE PRECISELY MEASURED THAN TIME!
And nothing keeps track of time more precisely and trouble free than La Crosse Technology radio controlled clocks.
Since the beginning of time, man has been fascinated with the measurement of time and has devised more accurate
machines to trap and measure time. Today, time is precisely measured in the United States by the most accurate
clock in North America, the Atomic Clock of the US National Institute of Standards and Technology, Time and
