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 units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into
the indoor weather station.
(All outdoor remotes must be started before the indoor 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 an
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.
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 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 80 ft. in a straight line.
Note: Fog and mist will not harm your remote temperature sensor but direct rain
must be avoided.
Note: 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 15 minutes. If there is no temperature reading in the OUTDOOR LCD
after 15 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 temperature signal, you will need to follow the battery
installation procedure again.
To complete the set up of your wireless weather station after the 15 minutes have
passed please follow the steps that follow in the Detailed Set-Up Guide.

DETAILED SET-UP GUIDE
BATTERY INSTALLATION
A. REMOTE TEMPERATURE SENSOR
1. Remove the mounting bracket. The
bracket snaps on and off easily.
2. Remove the battery cover, by sliding the
cover down.
3. Observing the correct polarity install 2
AA batteries. The batteries will fit tightly
(to avoid start-up problems make sure
they do not spring free).
4. Replace the battery cover by sliding upwards. Be sure battery
cover is on securely.
B. INDOOR WEATHER STATION
1. Remove the battery cover. To
do this, insert a solid object in
the space 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.
Note: Immediately after the batteries have been installed, the LCD
(Liquid Crystal Display) will flash. Within 15 seconds the indoor
temperature, indoor relative humidity, and the weather icons (sun and
clouds) will be displayed. If not, remove batteries for 10 seconds and
reinstall. If the outdoor temperature is not displayed within four minutes,
remove batteries from both units, wait 30 seconds, and reinstall making
sure to install batteries into the remote temperature sensor first. The time
will show -:-- and start searching for the WWVB signal. If it successfully
receives the time signal (usually at night), it will display the correct time
(default time-zone is Eastern). You will need to adjust the time zone to
match your local time.

PROGRAM MODE
Programming Note: If 30 seconds is allowed to pass, or the CH button is
pressed during the programming mode, the unit will confirm/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
programming of sections IV through XI, you can advance to step 4 of the
next program setting. If you do leave the program setting (or want to
program a specific setting) follow each instructional step to program that
setting.
I. PROGRAMMING SEQUENCE AND DEFAULT SETTINGS
The programming sequence and default (factory) settings are as
follows:
LCD Contrast 5
Time Zone -5 (Eastern)
Daylight Saving Time 1 (on)
Radio-controlled time reception ON
12/24-hour time 12
Time 12:00
Year 2003
Day and Month 1.1.
Snooze (this function not used) 10
Temperature Format °F
Forecast Sensitivity 2
Please note that while there is a snooze adjustment in the programming this
is an unused function as there is no alarm on the indoor weather station.
II. FUNCTION KEYS
The function keys are located on the front of the unit directly below the
LCD.

the time setting.
VIII. 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
condition 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 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
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.
1. Press and hold the SET button for 5 seconds.
2. “LCD” will show in the time LCD and the number setting will
flash.
3. Press and release the SET button five times.
4. The time will flash in the time LCD.
