QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the Wireless Weather Station and remote thermo/hygro sensor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote thermo/hygro sensor first then into the Wireless Weather
Station.
(All remote thermo/hygro sensors must be started before the Wireless Weather Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and remote thermo/hygro sensor will start to talk to each other
and the display will show both the indoor temperature/humidity and an outdoor temperature/humidity.
If the Wireless 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 and humidity are displayed for
15 minutes you can place your remote thermo/hygro sensor outdoor and set your time.
The remote thermo-hygro sensor should be placed in a dry, shaded area. The thermo-hygro sensor
has a range of 330 feet. Keep in mind that the 330 feet is in open air with no obstructions and that radio
waves DO NOT curve around objects. Actual transmission range will vary depending on what is in the
path of the signal. Each obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut
signal range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall, so that the
signal has to pass through one interior wall, one exterior wall, and across the 10 feet width of the room
between the 2 walls. The first wall will reduce the range to 165 feet, and the second wall will reduce the
range to 87 feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal
range.
This allowance is typically enough for a frame wall with non-metallic siding; however certain materials
can reduce range even further. Metal siding, stucco, and some types of glass can reduce signal range
by as much as 3/4 or more, compared to the 1/2 reduction typical of most obstructions. It is possible to
receive a signal through these materials, however maximum range will be much less due to their ten-
dency to absorb or reflect a much larger portion of the sensor's signal.

Battery Installation
I. BATTERY INSTALLATION (When on thermo/hygro sensor is being used)
1. First, insert the batteries to the thermo/hygro sensor (see "A. Remote Thermo/hygro Sensor"
below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the Weather Station (see "B.
Wireless Weather Station" below). Once the batteries are in place, all segments of the LCD will
light up briefly. Following the indoor temperature and humidity, and the time as 12:00 will be displayed.
If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data signal from the sensor.
The outdoor temperature and humidity should then be displayed on the Weather Station. If this does
not happen after 2 minutes, the batteries will need to be removed from both units and reset from
step 1 and the signal reception icon is no longer shown.
A. Remote Thermo/Hygro 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).

ABOUT WWVB (radio-controlled time)
14
The NIST (National Institute of Standards and Technology-Time and Frequency Division) radio station,
14
WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout
16
the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal
16
antenna in the indoor weather station. However, due to the nature of the Earth's Ionosphere, reception
17 is very limited during daylight hours. The Wireless Weather Stations will search for a signal every night
when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in
18
Boulder, Colorado. A team of atomic physicists continually measure every second of every day to an
accuracy of ten billionths of a second a 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 infor-
mation about WWVB please see the NIST website at http://www.boulder.nist.gov/timefreq/stations/

4. Replace the battery cover by sliding upwards. Be sure battery cover is on securely.
Battery Compartment
B. Wireless Weather Station
1. Remove the battery cover (the cover has white writing on it).
2. Observe the correct polarity, and install three Alkaline AA batteries.
3. Do not press any buttons for at least ten minutes. If a button is pressed before the indoor weather
station has received information from the TX29UD-TH sensor, no data will be received from that
sensor until reset.
4. Replace the battery cover.

* When the signal is successfully received by the Weather Station, the icon will be switched on. (If not
successful, the icon will not be shown in LCD) So the user can easily see whether the last reception
was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows
that a reception is being done now.
• If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the fre-
quency is changed to 920MHz and the learning is tried another 45 seconds. If still not successful
the reception is tried for 45 seconds on 910MHz. This will also be done for re-synchronization.
INSTANT TRANSMISSION is the state-of-the-art new wireless
