NOTE: The weather forecast accuracy is approximately 70%.
The main unit display shows forecasted (predicted) not current
conditions. The SUNNY icon indicates clear weather, even when
displayed during the night-time.


If the main unit display line for the remote sensor reading goes blank, press
and hold DOWN (▼) button for 2 seconds to begin a new signal search. If the
signal still isn't received, please make sure that:
• The remote sensor is in its proper location.
• The distance between main unit and remote sensor is not over 100
feet (30 meters)
• The path between units is clear of obstacles. Shorten the distance if
• Fresh batteries are installed correctly in both remote sensor and main
If there is no reception, please perform the following steps:
• Bring the main unit and remote sensor close together.
• Remove four (4) small screws from the back of the remote sensor with
small Phillips screwdriver, and open the battery compartment.
• Remove the batteries from the battery compartment and reinstall them
in the same manner. Remote sensor LED indicator will flash showing

Signals from the other household devices such as wireless doorbells, home
security systems, and entry control, may interfere with this product or cause
temporary reception interruption. This is normal and will not affect the general
performance of the product. The transmission and reception of the temperature
readings will resume once the interference subsides.


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 Wall 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
