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 weather
station. However, due to the nature of the earth’s ionosphere, reception is very
limited during daylight hours. The weather station 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.

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor weather station and remote temperature sensor 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 indoor weather station.
(All remote temperature sensors must be started before the indoor
weather station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the indoor weather station and remote temperature sensor will start to
talk to each other and the indoor weather station will show both the indoor
temperature and an outdoor temperature. If the indoor weather station 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 indoor weather station after the 10 minutes have
passed please follow the steps on pages 8 and 9.
Note: The remote temperature sensor transmits a signal every 3 minutes;
after the batteries have been installed, the indoor weather station will
search for the signal for a duration of 5 minutes. If there is no temperature
reading in the OUTDOOR LCD after 5 minutes, make sure the units are
within range of each other or repeat the battery installation procedure.

This method requires you to do nothing except wait for the signal
to be received and to select a time zone. Reception usually takes
approximately 6-10 minutes during optimal conditions. The best
conditions for reception is at night, between midnight and 6:00
AM—when there is less atmospheric interference. To keep your
time as accurate as possible, the weather station conducts a
WWVB search every night between these hours and overrides any
manually set time. The WWVB tower icon (appearing in the TIME
LCD) will flash when a signal-search is in progress, will remain
steady when the signal has been received and nothing will be
displayed in all other situations. If the WWVB time has not been
received after 10 minutes of battery installation, you may manually
set the time or leave the time function alone (reception will occur
regardless).
B. MANUAL TIME SETTING
1. Press and hold the “SET” button for 3 seconds or until “12h”
flashes in the DATE LCD.
