QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the intelligent weather station and remote temperature/humidity sensor 3 to 5 feet
apart.
2. Batteries should be out of both the intelligent weather station and remote
temperature/humidity sensor units for 10 minutes.
3. Place the batteries into the remote temperature/humidity sensor first then into the
intelligent weather station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the intelligent weather station and remote temperature/humidity sensor will start to talk to
each other and the display will show the intelligent temperature/humidity, outdoor temperature/humidity,
heat index and dew point. If the intelligent 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/humidity 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 wall 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 transmits a signal every minute. After the batteries have
been installed, the intelligent 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 intelligent weather station receives the signal from the remote
temperature/humidity sensor, 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.

HOW TO INSTALL AND REPLACE BATTERIES IN THE INTELLIGENT WEATHER STATION
The intelligent weather station uses 3 AA (alkaline recommended) batteries. When the batteries need to be replaced the
low battery symbol will appear on the LCD.
To install and replace the batteries, please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center of the
battery compartment and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see battery compartment
marking).
3. Replace battery cover.
HOW TO INSTALL AND REPLACE BATTERIES IN THE REMOTE TEMPERATURE/HUMIDITY
SENSOR
The remote temperature/humidity sensor uses 2 x AA IEC LR6, 1.5V batteries. To install and replace
the batteries, please follow the steps below:
1. Remove the battery cover at the front side with a small screwdriver.
2. Insert the batteries, observing the correct polarity (see battery compartment marking).
3. Replace the battery cover on the unit.
Note:
When changing the batteries in any of the units, all units need to be reset by following the setting up procedures. This is
because the transmitter at start-up assigns a random security code and this code must be received and stored by the
intelligent weather station in the first 3 minutes of power being supplied to it.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.
Please participate in the preservation of the environment. Return used batteries to an authorized
facility.
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.

WWVB reception function has been set ON. When it does receive the signal, it will change the manually set time into
the received time. During reception attempts the WWVB tower icon will flash. If reception has been unsuccessful, then
the WWVB tower icon will not appear but reception will still be attempted the following hour.
CALENDAR SETTING:
The date default of the intelligent weather station is 1. 1. in the year 2004. Once the radio-controlled time signals are
received, the date is automatically updated. However, if the signals are not received, the date can also be set manually.

RELATIVE AIR PRESSURE UNIT SETTING
The relative air pressure unit can be set in inHg, hPa or mmHg unit. (default unit is inHg).
1. Use the MAX/+ or MIN/- key to toggle between “inHg”, “hPa” or “mmHg”
2. Confirm with the SET key and enter the Relative Pressure Value setting.
Note:
The default reference pressure value of the barometer is 29.91 inHg (1013 hPa). For an exact measurement it is
necessary to first adjust the barometer to your local relative air pressure (related to elevation above sea level).
Ask for the present atmospheric pressure of your home area (Local weather service, calibrated instruments in public
buildings, airport).
RELATIVE PRESSURE VALUE SETTING
The default relative pressure value is 29.91 inHg (1013 hPa). This corresponds to the average air pressure. Pressure
below this is referred to as low-pressure area (weather to become worse), pressure above as high-pressure area
(weather to improve). The relative air pressure can be manually set to another value within the range of 28.35 to 30.72
inHg (960 – 1040 hPa or 720 – 781 mmHg) for a better reference.
1. The current relative pressure value will start flashing
2. Use the MAX/+ or MIN/- key to increase or decrease the value. Keep holding the key allows the value to advance
faster.
3. Confirm with the SET key and enter the Language display setting.
Note:
This calibration facility is useful for those users living at various elevations above sea level, but wanting their air
pressure display based on sea level elevation.
LANGUAGE DISPLAY SETTING:
The language for the calendar and “Intelligent” weather information display can be set to view in English (E), German
(D), or French (F). Default setting is English. To set another language:
1. Use the MAX/+ or MIN/- key to set the desired language.
2. Confirm with the SET key and exit the Manual settings.
