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.

DETAILED SET-UP GUIDE

I. 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, each

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

Battery

Cover

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. 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.

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, “-5hr” (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

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).
