ABOUT WWVB (Radio Controlled Time)

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

Division) WWVB radio statio n is located in Ft. Collins, Colo rado, 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

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 12:00am to 6:00am.

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 to fall away from the unit. Place the screw partially

back into its hole, and angle it slightly—so the thread s 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 provided at the lower-central position of the battery cover, then push up and

Battery Cover

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 buttons are pressed during programming modes the unit will confirm/set the last information entered—the d isplay 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 Secondary Buttons are located directly below the Primary Buttons, and

behind the La Crosse Technology shield on the face of the unit. To access the Secondary Buttons: place a solid object in the slot (above the shield) and gently pull out and down.

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 the CH button to toggle between 12 and 24-hour time.

3. Press 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.

If 30 seconds is allowed to pass, or either the IN or

2. Press the SET button 1 more time to enter the Time Zone setting mode. The default Time Zone “-5” will flash in the DATE LCD.

3. 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.

TIME ZONES

GMT 0

Atlantic -4 EST; Eastern -5 CST; Central -6

MST; Mountain -7

PST; Pacific -8

ALA; Alaska -9

HAW; Hawaii -10

There are more time zones represented by numbers than there are

Note:

represented by 3 letter abbreviations. If you live in North America you need only be concerned with the ones in the chart above.

4. Press 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” or “24 h” flashes in the DATE LCD.

2. Press the SET button 2 more times to reach the DST selection mode. “DST 1” is the default setting and w ill be flashing in the DATE LCD.

3. Press the CH button to select “DST 0” or “DST 1.”

4. “DST 0” indicates that the feature is off and the WWV B will not change times automatically. “DST 1” indicates that the feature is on and the WWVB will chan ge times automatically.
