Transmission Interference; Wwvb Radio Controlled Time - NexxTech Wireless thermometer User Manual

Transmission Interference

Signals from 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.

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
most of North America at 60 KHz frequency. This unit
can receive the WWVB signal through the internal
antenna from up to 3,218 kms (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 nightime hours, atmospheric disturbances are
typically less severe and radio reception may improve.
A single daily reception is sufficient enough to keep the
clock accuracy within one second.
• Make sure the unit is positioned at least 2 meters (8 feet)
away 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 unit near the window for better reception.
