II.PROGRAMMING
A. SETTING THE TIME
There are two methods by which the time and date can be set: 1) Automatically via WWVB reception, or 2) Manually.
B. WWVB (Radio-Controlled Time)
This method requires you to do nothing, except wait for the signal to be received, and to select a time zone. Reception usually takes approximately 6-10 minutes during optimal conditions. The best conditions for reception is at night, between midnight and 6:00 am—when there is less atmospheric interference. To keep your time as accurate as possible, the alarm clock conducts a WWVB search every night between these hours, and overrides any manually set time. The WWVB tower icon (appearing in the TIME LCD) will flash when a signalsearch is in progress and a signal is being received, and will remain steady when the

signal has been received. If the WWVB time has not been received after 10 minutes of battery installation, you may manually set the time or wait for the WWVB reception.
About Radio-Controlled Time signal, 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. However, 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
