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 Atomic Time Clock in your weather station can
receive this WWVB signal through the internal antenna from up to 2,000 miles away. Due to the
nature of the Earthʼs 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 unitʼs 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 Projection Clock near the window for better reception.
Once the atomic time signal is received, the date and time will be set automatically, and the
will appear.
After the clock is set manually, place the main unit 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.
To enable or disable the atomic time receiver:
• Press and hold UP
flashing next to the clock icon. If reception is disabled, the triangular tower icon will disappear.

TEMPERATURE AND HUMIDITY MODE

The weather station supports up to 3 remote thermo hygrometers corresponding to a separate channel
of the temperature and relative humidity display. The temperature can be displayed in Celsius (ºC) or
Fahrenheit (ºF).
The main unit carries the temperature and humidity sensor and uses this indoors data to calculate an
indoors comfort level - Wet, Comfort or Dry.
A temperature alert function is available for each channel. It can be programmed to sound if the
channel temperature exceeds or falls below the pre-set upper and lower limit.
