ABOUT WWVB (Radio Controlled Time)

The NIST (National Institute of Standards and Technology—Time and Frequency

Division) WWVB radio station is located in Ft. Co llins, 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

4

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

1. Insert two AAA batteries into the Remote Control Sender.

2. Insert two AA batteries into the WEATHER STATION.

3. Wait 5 minutes, or until the outdoor temperature is displayed in the

OUTDOOR LCD (Liquid Crystal Display).

4. Wait 6-10 minutes (in ideal reception conditions) for the WWVB time

to be displayed in the TIME LCD. If the WWVB takes longer to set,
you may manually set the time (see complete instructions), or you can
wait until after the weather station conducts its programmed search at
the ideal reception time period of 12:00 am to 6:00 am.

5. Mount the units, ensuring that all units are sending and receiving

signals.

The Remote Control Sender transmits a signal every 3 minutes; after

Note:

the batteries have been installed, the 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.

DETAILED SET-UP GUIDE

I. BATTERY INSTALLATION

A. REMOTE CONTROL SENDER

1. Remove the mounting bracket. The bracket snaps on and off
easily.

2. Remove the battery cover by
removing the flathead screw
located on the backside of the

Battery
Cover

unit, in the lower-central position.
The rubber weather-seal creates a
tight seal for the battery cover and
does not allow the battery cover

5

to fall away from the unit. Place the screw partially back into
its hole and angle it slightly—so the threads grab the battery
cover. With the screw, pull the battery cover off.

3. Observing the correct polarity install 2 AAA batteries. The
batteries will fit tightly (to avoid start-up problems make sure
they do not spring free).

4. Check the LCD screen of the Remote Control Sender to see if
there is a temperature reading. If there is no reading, check
the polarity of the batteries or replace with new batteries.

5. Check to make sure that the rubber weather-seal is in place
and replace the battery cover, screw and mounting bracket.

B. WEATHER STATION

1. Remove the battery cover. To do
this, insert a solid object in the space

Battery
Cover

provided at the lower-central
position of the battery cover, then
push up and pull out on the battery
cover.

2. Observe the correct polarity, and
install 2 AA batteries.

3. Replace the battery cover.

Immediately after the batteries have been installed, each

Note:

LCD (Liquid Crystal Display) will flash and a tone will sound.
Within a few seconds the indoor temperature, indoor relative
humidity and the weather icons (sun and clouds) will be displayed.
If not, then remove batteries for 10 seconds and reinstall. If the
outdoor temperature is not displayed within four minutes, remove
batteries from both units, wait 10 seconds, and reinstall. The time
will show -:-- and start searching for the signal. If it successfully
receives the time signal (usually at night), it will display the
correct time (default is Eastern).

PROGRAM MODE

Programming Note:

the OUT button is pressed during programming modes, the unit will set the
last information entered—the display will stop flashing and return to
normal time-date readings. If you don’t leave the program mode during the
