ABOUT RADIO-CONTROLLED TIME - WWVB

The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time and date signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the alarm clock. Due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The alarm clock will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. More information on the atomic clock and WWVB can be found at

PROGRAM MODE

Following is a list of steps to set up your new La Crosse Technology travel alarm clock.

•Please begin by removing the battery

cover on the rear of the travel alarm shown in figure one.

•Next insert one AA alkaline battery into the battery compartment making sure to observe the correct polarity.

•When inserting the battery be sure not to press any of the buttons on the travel alarm as this will interrupt the WWVB search and may cause the

travel alarm to not pick up the radio-controlled time signal.

•Now replace the battery cover and face the travel alarm with the back of the unit towards Colorado (this has been found to help the unit pick up the WWVB signal).

•When the WWVB signal is received a tower icon will appear on the left side of the LCD display.

NOTE: Due to the nature of the WWVB signal it may take overnight for the travel alarm to receive the signal and set. Adverse weather conditions may also affect the travel alarms’ ability to receive the signal. In some cases it may take several nights for the travel alarm to set.
