GENERAL INFORMATION
BATTERIES: WHAT DO I NEED TO KNOW ABOUT BATTERIES?
•Good fresh batteries are important for best performance in your sensors and as backup in
your station.
•Batteries with an expiration date of 2025, were manufactured in 2015.
•We recommend batteries with an expiration date no more than 6 years in advance of the
current year for best performance.
•A minimum voltage of 1.48 v per battery is required for best performance.
•Lithium batteries may be used in outdoor sensors. Alkaline batteries for the station.
CAN I OPERATE MY STATION ON BATTERY POWER ONLY?
•No, the power cord is required for your color station to work. Batteries are for backup.
•The Mini Display operates on batteries only.
BATTERIES: WHAT DO THE BATTERY ICONS MEAN?
•When Battery Indicator shows in the outdoor area, replace batteries in your Outdoor
Sensor.
•When Battery Indicator shows next to your Time or the Indoor area, replace batteries in
your Station.
SENSOR AND STATION
Your CA82738 (CA82738-1 & CA82738-2) stations comes with:
TX141TH-Bv3 Thermo-hygro sensor 433MHz RF
Transmission Range 330 feet (100 meters) open air.
WHAT ARE THE POWER REQUIREMENTS?
TX141TH-Bv3: 2-AA batteries

3 | P a g e
CA82738-1: 5 volt power cord (required) and 2-AA batteries for optional backup of your
time and date. Power cord is required.
CA82738-2: 2-AAA batteries
WILL THESE STATION WORK IN OTHER COUNTRIES?
•No. The color station will only work on 120 volt systems.
SETUP: HOW DO I SETUP MY STATION?
1. Insert 2-AA batteries into your Outdoor Sensor.
2. Insert the 5 volt power cord into an outlet, then into your Color Display. Optional: Insert
2-AA batteries for backup.
3. Insert 2-AAA batteries into your Mini Display.
4. Adjust time and date settings on each display.
5. Once the Outdoor Sensor is reading to each of your displays, place it outside in a
shaded location.
.MOUNTING: WHERE DO I POSITION MY SENSOR & STATION?
•Watch sensor mounting video: http://bit.ly/TH_SensorMounting
•Place your thermo-hygro sensor at least 6 feet off the ground.
•For accurate temperature readings your sensor needs to be shaded from the sun and in a
well ventilated area. Trapped moisture will cause inaccurate readings.
•Mount your sensor vertically to allow moisture to drain out the bottom.
•Preferred location is on a north facing wall under an eave or deck rail.
•Avoid placing near a metal roof that will cause it to read high on sunny days.
•Avoid other sources of heat such as soffit vents, and window or door frames.
•For accurate humidity readings, avoid placement near vegetation and lakes or other
bodies of water when possible.
•Maximum transmission distance from your thermos-hygro sensor to your station, in open
air is 330 feet (100 meters).
•Insert the mounting screw through the front of the transmitter and into the wall. Tighten
the screw to snug (do not over tighten).
POSITION STATIONS
Your stations are designed for placement on a desk or countertop.
•Position within reach of an outlet that is always active. Some outlets in living rooms and
in bedrooms may only be active when the light switch is on.
•This color station must operate with the 5 volt power cord in order to receive sensor
updates. Operation on battery power will only maintain time/date settings if you need to
move your station.

4 | P a g e
•Best reception occurs when only one wall is between your station and your sensor
outside.
•Position you station six feet from other electronics and wireless devices. If you suspect RF
(radio frequency) interference, simply move your weather station a few feet.
WHAT IS DISTANCE | RESISTANCE | INTERFERENCE?
Distance:
•The maximum transmitting range in open air is over 330 feet (100 meters) between your
sensor and your station.
•Consider the signal path from your station to your sensor as a straight line.
•Consider the distance the station is from other electronics in the home.
Resistance:
•Each obstacle: walls, windows, vegetation, stucco, concrete, and large metal objects will
reduce the effective signal range by about one-half.
•Mounting your sensors on a metal fence can significantly reduce the effective signal
range.
Interference:
•Consider electronics in the signal path between your sensor and your station.
•Simple relocation of your sensor or the station may correct an interference issue.
•Windows can reflect the radio signal.
•Metal will absorb the RF (radio frequency) signal.
•Stucco held to the wall by a metal mesh will cause interference.
•Transmitting antennas from: ham radios, emergency dispatch centers, airports, military
bases, etc. may cause interference.
•Electrical wires, utilities, cables, etc. may create interference if too close.

DOES THIS STATION HAVE 12 HOUR AND 24 HOUR TIME OPTIONS?
•Yes, you can select 12 hour or 24 hour time format in the program menu of both stations.
TROUBLESHOOTING
HOW DO I CHANGE BATTERIES IN MY SENSORS WITHOUT LOSING
DATA?
Color Station:
We designed this station for convenience, so that a simple change of batteries does not lose
data or require you to power down your station.
•When Battery Indicator shows next to the Outdoor Humidity, replace batteries in your
Outdoor Sensor.
•Then hold the PLUS (+) button for 3 seconds and your station will search for your sensor.
•When changing the batteries in the color station, continue using the power cord. After
replacing the batteries, no other action is needed. The batteries in the station only
maintain time/date in the event of a power outage.
Mini Display:
Hold the +/SEARCH button to search for the outdoor sensor.
FACTORY RESET: HOW DO I FACTORY RESET MY STATION?
•Basically this is a great way to return your station to “out of the box” condition.
•This is more effective than removing all power for clearing out the station.
•All history records will be removed, so write down anything you want to keep.
To factory either station:
1. Bring your sensor in, and place 5-10 feet from both stations.
2. Remove power (batteries and power cord) from stations and sensor for 15 minutes.
3. With power removed press any button 20 times.
4. Insert power cord and batteries into sensor and stations.
5. Allow 15 minutes for them to connect several times.
6. Place sensor back outside.
DASHES TEMP/HUMIDITY: WHY DOES MY THERMO-HYGRO SENSOR
SHOW DASHES ON THE STATION?
Dashes indicate the connection is lost between your station and the outdoor sensor.
•My first thought is always to check that my batteries are good. If it has been working and
now is not, low batteries are the most common connection problem.
•Next, check your distance, resistance and interference. If everything was working
previously at the same location, this is likely not the issue. However sometimes there is

10 | P a g e
new growth on trees or bushes that causing another barrier. Radio Frequency (RF) signal
does not travel well through foliage due to the moisture content.
•Occasionally adding a new wireless electronic device to the home will cross the signal
path for the sensor. If this occurs try moving your station a few feet or turning the
station 90 degrees for a better angle to receive the sensor signal.
•When you have good batteries, and good location, hold the PLUS (+) button (Color
Station) or +/SEARCH button (Mini Display) for three seconds to search for your sensor.
If you regain connection while the sensor is mounted, great. If you do not regain
connection, bring the sensor within 10 feet of the station and complete a factory reset.
WHY DON’T MY TEMPERATURE/HUMIDITY READINGS
ON MY STATION MATCH THE WEATHER REPORT?
•Your temperature and humidity readings are from you sensor at your location. Your local
reporting station can be miles away so readings may differ.
TEMP ACCURACY: WHY DOES MY THERMO-HYGRO SENSOR READ
INCCURATELY?
•The thermo-hygro sensor reads the environment. If your sensor reads high during the
day but not at night it is a mounting problem.
•Side-by-side test: Bring the thermo-hygro sensor in the house and place it next to your
station for 2 hours.
•Compare indoor and outdoor temperature. The temperatures should be within 4 degrees
to be within tolerance. The humidity should be within 14% to be within tolerance.
•If the sensor reads correctly when next to your station then try a different location
outside.
•Look for heat sources such as sunlight, door or window frames, or reflected heat that
may cause inaccurate readings.
•If your temperature is reading low, and location is not an issue, you may have a bad
sensor.
WHAT DOES A READING OF “HI” OR “LO” MEAN?
•If your outdoor temperature reading shows “HI” or “LO”, check that your batteries are
good.
•Overpowered or underpowered batteries can cause this reading.
•If batteries are good, replace the outdoor sensor.
•If your temperature is fine but your humidity is reading “HI” or “LO” or dashes, your
humidity may be below 10% Relative Humidity. Your sensor does not read below 10%
humidity.
