La Crosse Technology® atomic 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®
atomic clocks can be manually set and used anywhere.
Please Note: WWVB time will over ride a manual setting.
For more information on the NIST and radio controlled time, see

TO SET THE TIME USING THE MANUAL TIME SET BUTTON
In some cases, the La Crosse Technology® atomic 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 Manual Time Set button,
located at the back of the clock to manually set the time. To do this:
1.
Remove the battery and press the Manual set button 10 times.
2.
Insert 1 new AA Alkaline battery.
3.
Press and hold the Manual Set button until the second hand of the clock
moves to the 12 position.
4.
Release the Manual Set button and again press and hold the Manual Set
button. The minute and hour hands will fast-forward while the button is held.
5.
Keep holding the Manual Set button until the time is set as required.
6.
Release the button. About 3 seconds later, the second hands will start to
move and the clock is now running with manual time.
Note:
When the clock displays manual time, it will continue to try to receive the WWVB
signal at each of the even numbered hours: 0:00, 2:00, 4:00, 6:00 … 20:00 &
22:00.
DIGITAL CLOCK
1.
Remove the battery cover at the back of the clock and insert 1 AA Alkaline
battery in the battery compartment.
2.
All segments of the LCD will light up briefly, then the display “-:--“ and the
current indoor temperature will be displayed
Note: If the Display time is pressed while the analog clock is still searching
for the WWVB signal, the digital clock will display “--/--“ for the date and “-:--
“ for the world time.
3.
Wait for the digital clock to receive the WWVB time and date from the
analog clock. Then the digital clock will start normal runs.
