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.
For more information on WWVB and the atomic clock 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
apart.
2. Batteries should be out of both units.
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 15 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 15 minutes please retry the set up as stated above.
After both indoor and outdoor temperatures are displayed for 15 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 can have up to 30 feet of
resistance and an interior wall can have up to 20 feet of resistance depending upon
the type of construction. 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.

DETAILED SET-UP GUIDE
I. BATTERY INSTALLATION
6
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, each LCD
(Liquid Crystal Display) will flash and a tone will sound. Within a few
seconds the indoor temperature will be displayed. If not, then remove the
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
WWVB signal. If it successfully receives the time signal (usually at night),
it will display the correct time (default is Eastern).

PROGRAM MODE
Programming Note: If 30 seconds are allowed to pass or either the IN or
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
programming of sections III through VIII, you can advance to step 3 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
The sequence for programming the indoor weather station and the default
(factory) settings are:
1. 12/24 hour time setting 12 hour
2. Time Zone Zo -5 (eastern)
3. Daylight Saving Time 1 (on)
4. Time – hour 12
5. Time – minute 00
6. Date – day of the week mo (Monday)
7. Date – month 1 (January)
8. Date – day of the month 1
9. Date – Year 1999
10. Temperature °F
11. LCD (liquid crystal display) contrast 5
12. End of sequence
The programming instructions are given in a manner so that each setting is
done separately. On initial set-up and after inserting new batteries to
program all functions simply disregard the first two steps of each section
starting with the Time Zone Setting.

II. FUNCTION KEYS
The function keys are operated by pressing the top
or bottom of the key corresponding to the
operation that you want to perform.

II. 12 OR 24 HOUR TIME SETTING
1. Press and hold the “SET”
button for 3 seconds or until
“12 h” flashes in the DATE
LCD.
2. Press and release the “CH”
button to toggle between 12
and 24-hour time.
3. Press and release the “SET” button to confirm the 12/24-hour
setting and to advance to Time Zone Setting.
III. TIME ZONE SETTING
The default time zone is EST, “Zo -5” (Eastern Standard Time), to
change this setting:
1. Press and hold the “SET” button for 3 seconds or until “12 h”
OR “24 h” flashes in the
DATE LCD.
2. Press and release the “SET”
button 1 more time to enter
the Time Zone setting mode.
3. The default Time Zone “Zo-
5” will flash in the DATE
LCD.

4. Select your appropriate
time zone using the
“CH” button. During
selection of the Time
Zone, the 3 letter
abbreviations for the time
zones found in North
America will flash across
the top of the TIME
LCD. Observe the chart
below, showing the
corresponding
abbreviations, time zones, and codes.

Note: There are more time zones represented by numbers than there are
represented by 3 letter abbreviations. If you live in North America you
need only be concerned with the ones in the chart above.
5. Press and release the “SET” button to confirm and advance to
the Daylight Saving Time setting.
IV. DAYLIGHT SAVING TIME (DST) SETTING
1. Press and hold the “SET” button for 3 seconds or until “12 h”

and will be flashing in the
DATE LCD.
4. Press and release the “CH”
button to select “DST 0” or
“DST 1.”
5. “DST 0” indicates that the feature is off and the WWVB will
not change times automatically. “DST 1” indicates that the
feature is on and the WWVB will change times automatically.

6. Press and release the “SET” button to confirm and advance to
the Time setting mode.
V. TIME
There are two methods by which the time 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 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 (once reception has
occurred the WWVB time will over ride the manual time and set
automatically).
B. MANUAL TIME SETTING
1. Press and hold the “SET” button for 3 seconds or until “12h”
flashes in the DATE LCD.
2. Press and release the “SET” button 3 more times.
3. The hour digit (default of “12” should be flashing in the
TIME LCD).
4. Press and release the “CH” button to change the hour. Press
the “CH” button once and the hour will increase by one,
twice and the hour will increase by two, etc.
