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 and date 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. For more information on the atomic clock and 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 weather station and remote temperature sensor 3 to 5 feet apart.
2. Batteries should be out of both the indoor weather station and remote temperature sensor units for 10
minutes.
3. Place the batteries into the remote temperature sensor first then into the indoor weather station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature sensor will start to talk to each other and the
display will show the indoor temperature/humidity, and outdoor temperature. If the indoor weather station does
not display all information after the 15 minutes please retry the set up as stated above. After all information has
been displayed for 15 minutes you can place your sensor outdoors and set your time.
Important Notes on Set-up and Operation
• The remote temperature sensor should be placed in a dry, shaded area.
• Fog and mist will not harm your remote temperature sensor but direct rain must be avoided.
• The remote temperature sensor has a range of 330 feet. Any walls that the signal will have to pass through
will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall
can have up to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a straight
line.
• The remote temperature sensor transmits a signal every minute. After the batteries have been installed, the
indoor weather station will search for the signal for a duration of 4 minutes. If there is no temperature
reading in the OUTDOOR LCD after 4 minutes, make sure the units are within range of each other, or
repeat the battery installation procedure.
• If a button is pressed before the indoor weather station receives the signal from the remote temperature
sensor, you will need to follow the battery installation procedure again.
To complete the set up of your new wireless weather station after the 15 minutes have passed please follow the
steps that follow in the Detailed Set-Up Guide.

VII. TIME SETTING
There are two methods by which the time and date can be set:
A) Automatically via WWVB reception, or
B) Manually.
A. WWVB (Remote Control Time)
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 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 indoor 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 and a signal
is being received, and will remain steady when the signal has been received. If the WWVB time has
not been received after 15 minutes of battery installation, you may manually set the time or leave the
time function alone (reception will occur regardless).
B. MANUAL TIME SETTING
Note: When in the 12-hour format “P.M.” will appear to the left of the hour in the time LCD
between the hours of noon and midnight.
Note: Reception of the WWVB signal will automatically set the time. The reception of the
signal will override any programmed time.
