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 battery AAA 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 [E. DOWN (  ) BUTTON ] 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.
