WWVB RADIO CONTROLLED TIME

The NIST (National Institute of Standards and
Technology) radio station (WWVB) is located in Ft.
Collins, Colorado. It transmits an exact time signal
continuously throughout the most of the continental
United States at 60 KHz frequency. The Travel Alarm
Clock can receive this WWVB signal through the
internal antenna from up to 2,000 miles away. Due to
the nature of the Earth’s ionosphere, reception can be
limited during the daylight hours. The radio controlled
clock will search for an alternate station that receives
the atomic time signal from the NIST Atomic clock in
Boulder, Colorado.
The WWVB tower icon on the unit’s display will flash
indicating a radio signal reception from the WWVB
station. If the tower icon is not fully lit, or if the time
and date are not set automatically, please consider the
following:

* During night-time hours, atmospheric disturbances
 are typically less severe and radio signal reception
 may improve. A single daily reception is sufficient
 enough to keep the clock accuracy within 1 second.
* Make sure the unit is positioned at 8 feet (2 meters)
 distance from any interference source such as a TV,
 computer monitor, microwave, etc.
* Within concrete wall rooms such as basements or
 office buildings, the received signal may be weakened.

 Always place the Table Alarm Clock near the

 window for better reception.

GETTING STARTED
BATTERY INSTALLATION

* Open the battery compartment door.
*Install 2 batteries AA size 1.5V matching the polarity
 as shown in the battery compartment.
* Replace the battery compartment door.

RADIO CONTROLLED CLOCK

After installing batteries, set the time manually.
ONE TIME SET is needed ONLY when first used.
The clock will update the time automatically afterwards.
Once the atomic time signal is received, the date and time
will be set automatically, and the [ ] icon will appear.

After the clock is set manually, place it by the window for
the better reception. The atomic clock receiver is
programmed that it will continue to search for the atomic
time signal daily for every hour between 1:00 am and
4:30 am. Once the time signal has been successfully
received, the time and date will be updated automatically.

CALENDAR AND CLOCK DISPLAY MODES

Precise time is displayed in hour­minutes-seconds format in the middle
line of the Atomic Alarm Clock.
The date is displayed in month-date
format on the top line next to the day
of the week.
