The La Crosse Technology clock is designed for indoor or outdoor use. For indoor locations, 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. For outdoor locations, select a location sheltered from direct sunlight, preferably under a roof or porch area, and facing Colorado for better reception of the WWVB signal. Although the clock’s case is weather resistant, it is not waterproof. Avoid exposing the clock directly to sunlight, rain, snow or extreme weather conditions as it may cause damage and the clock will malfunction. High humidity combined with a hot sunny day and a cool night may also cause water to condense on the surface of the lens. The lens will clear up as soon as the weather is stabilized. This water condensation effect does not interfere with the function of the clock.

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.

SET THE TIME USING THE MANUAL TIME 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 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.Press and hold the Manual Set button.

2.The minutes and hours hands will fast-forward while the button is held.

3.Keep holding the Manual Set button until the time is set as required.

4.Release the button.

Note:

The clock will continuously search for WWVB at1:00 am, 3:00 am, 4:00 am, 6:00 am, 12:00 pm, 6:00 pm and 11:00 pm until a signal is received. Once the WWVB time signal is received, the WWVB time will override the manual set time.
