ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency
Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact
time signal continuously throughout the United States at 60 kHz. The signal can be
received up to 2, 000 miles away through the internal antenna in the temperature clock.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The temperature clock will search for a signal every night when
reception is best. The WWVB radio station derives its signal from the NIST Atomic
clock in Boulder, Colorado. A team of atomic physicists is continually measuring every
second, of every day, to an accuracy of ten billionths of a second per day. These
physicists have created an international standard, measuring a second as 9,192,631,770
vibrations of a Cesium-133 atom in a vacuum. For more information about WWVB
please see the NIST website at http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor station and outdoor remote 3 to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into the
temperature clock.
(All remote temperature sensors must be started before the temperature
clock)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the temperature clock and remote temperature sensor will start to talk to each
other and the temperature clock will show both the indoor temperature and an outdoor
temperature. If the temperature clock does not display both temperatures after the 10
minutes please retry the set up as stated above. After both indoor and outdoor
temperatures are displayed for 10 minutes you can place your remote temperature sensor
outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature sensor has a range of 80 feet. Any walls that the signal will have to pass
through will reduce distance. An outdoor wall or window will have 20 to 30 feet of
resistance and an interior wall will have 10 to 20 feet of resistance. Your distance plus
resistance should not exceed 80 ft. in a straight line.
NOTE: Fog and mist will not harm your remote temperature sensor but direct rain must
be avoided.
To complete the set up of your temperature clock after the 10 minutes have passed please
follow the steps below.

(Liquid Crystal Display) will briefly light up. The indoor temperature, the date as
“1/ 1”, the weekday as “MON”,
and the remote temperature will
be displayed (within three
minutes). Also, the time will
appear as “-:--” for
approximately 1 minute. The
WWVB search is automatically
initiated, and a tower icon
appears and flashes with the time colon (no tower icon will appear if the WWVB is
too weak to be detected, and the time display will remain on “-:--”). While the
WWVB search is being conducted various numbers will appear in the time display.
Within 10 minutes the temperature clock will either display the WWVB time, or
discontinue the search if the time is not found. If the search is cancelled “-:--” will
appear in the time LCD. The temperature clock will conduct a WWVB search every
hour until the first signal is found. Once the WWVB time is found, a search is
automatically conducted nightly at midnight. If the signal is found at midnight, the
