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 througho ut 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, 7 7 0 vibra tio ns of a Cesium -133 a to m in a vacuum. For more informa tion on the atomic clock and WWVB pl ease see the NIST website at http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

QUICK SET-UP GUIDE Hint: Use good quality Al kalin e Batteries and avoid rechargeable batteries.

1. Have the indoor weather station and remote temperature/humidity sensor 3 to 5 feet apart.

2. Batteries should be out of both the indoor weather station and remote temperatur e/humidity sensor units for 10

minutes.

3. Place the batteries into the remote temperature/humidity sensor first then into the indoor weather station.

4. DO NOT PRESS ANY BUTTONS FOR 15 MINU TES.

In this time the indoor weather station and remote temperature/humidity sensor will start to talk to each other and the displa y will show the indoor temperature/humidity, outdoor temperature/humidity, heat index and dew point. 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 sensors outdoors and set your time.

Important Notes on Set-up and Operation

• The remote temperature/humidity sensor should be placed in a dry, shaded area.

• Fog and mist will not harm your remote temperature/humidit y sensor but direct rain must be avoided.

• The remote temperature/humidity sensor has a range of 330 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 w all can have up to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a straight line.

• The remote temperature/humidity sensor transmi ts a signal ever y minu te. After the batte ries have bee n in stalled, the indoor

weather station will search for the signal for a duration of 4 minutes. If there is no temperature or humidity reading in the OUTDOOR LCD after 4 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 rec eive s the signal from the remote temperature/humidity sens or , you

will need to follow the battery installation procedure again.

To complete the set up of your new 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/HUMIDITY SENSOR

Battery compartment

1. Remove the battery cover by sliding the cover down.

2. Observing the correct polarity install 2 AA batteries. The batteries will fit tightly (to avoid start-up pro blems

make sure they do not spring free).

3. Replace the ba ttery cover by sliding upward s. Be sure battery cover is on se curely.

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 3 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. I f not, remove batteries for 10 seconds and reinstall. If the outdoor temperature is not displayed w i thin 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 12:00 and start searching for the WWVB signal. If it successfully receives the time signal (usually at night), it will display the correct time (default timezone is Eastern). You will need to adjust the time zone to match your local time.
