Batteries

•Half of all warranty issues can be resolved with fresh batteries of the appropriate

voltage.

•We suggest name brand alkaline batteries for indoor displays such as temperature

stations.

•Use batteries dated at least six years in advance of the current year. Batteries dated

earlier than six years from now may still work but may be unstable in performance.

•Alkaline batteries manufactured this year will have an expiration date 10 years in the

future. Battery technology has improved, and batteries will maintain voltage longer

in storage. However, the environment the batteries reside in for the 10 years can

deplete the power.

•Good name brand batteries make less noise, which reduces the chance of RF (radio

frequency) interference from the battery compartment. A minimum voltage of

1.48V for each battery is necessary for proper performance.

•Outdoor Transmitters: Use Alkaline batteries (or Lithium for temperatures below -

20°F/-28.8°C)

•Temperature station: Use Alkaline batteries. Overpowered or underpowered

batteries may cause loss of indoor readings, missing segments, dim display etc.

Temperature Station Factory Restart

•Remove all batteries from outdoor sensor and temperature station.

•Press one of the buttons on the temperature station at least 20 times to clear all

memory.

•Verify that the temperature station is blank before proceeding (there may be lines

painted on the screen).

•Leave both units without power for 15 minutes (very important).

•Insert fresh batteries into the outdoor sensor.

•Insert fresh batteries into the temperature station.

•Keep the outdoor sensor 5-10 feet from the temperature station.

•When RF connection is established, the temperature will appear on the station.

Allow the outdoor sensor and temperature station to sit together for 15 minutes to

establish a strong connection.

•Do not press buttons for 15 minutes.

•For optimum 433MHz transmission, the outdoor transmitter should be no more than

330 feet (100 meters, open air) from the Temperature station.

•See the section on mounting and distance/resistance/interference for details on

mounting the outdoor transmitter.

Outdoor Temperature Transmitter

Compatible Outdoor Transmitters

•A TX147 outdoor transmitter comes packaged with this Temperature station.

La Crosse Technology, Ltd. Page 3

Flashing Outdoor Temperature

•The outdoor Temperature reading will flash when the connection is first lost or

intermittent between the temperature station and the outdoor transmitter.

•Distance/Resistance is generally the cause of intermittent connection or loss of

connection between the transmitter and the temperature station.

•Check the position of the temperature station. Turn the temperature station 90

degrees towards the outdoor transmitter for better reception.

•Try the quick connect or factory restart.

•Batteries often resolve the connection issue.

Dashes shown for Outdoor Temperature

•Dashes means the connection is lost between the temperature station and the

outdoor transmitter.

•Batteries often resolve the connection.

•Distance/Resistance can cause loss of connection between the transmitter and the

temperature station.

•Reorientation of the temperature station 90 degrees towards the outdoor transmitter

may provide better reception.

•Try the quick connect or factory restart.

Inaccurate Outdoor Temperature Reading

•The outdoor transmitter reads the environment. When mounted in the home it will

read inside temperature.

•When the transmitter reads high during the day but not at night it is a positioning

problem.

•Side-by-side test: Bring the outdoor transmitter in the house and place it next to

the temperature station for 2 hours.

•Compare indoor and outdoor temperature. The temperatures should be within 4

degrees to be within tolerance. See the section on accuracy for details.

•If the transmitter reads correctly when next to the temperature station then try a

different location outside.

•Look for heat sources such as sunlight, door, or window frames, or reflected heat.

Intermittent Outdoor Temperature

•RF (radio frequency) communication may come and go occasionally. This can be

normal in some environments (e.g. moister climates). If transmitter signal is lost,

please wait 2-4 hours for the signal to reconnect on its own.

•Move the outdoor transmitter to a closer location.

•Freezer test: Confirm the temperature station is reading the correct outdoor

transmitter. Place the transmitter in the freezer for an hour and watch the

temperature drop on the temperature station.

•Indoor distance test: Please complete the restart with transmitter and

temperature station 5-10 feet apart and inside to establish a strong connection.

La Crosse Technology, Ltd. Page 4

•After 15 minutes if there is a reading in the outdoor temperature area, move the

transmitter to another room with one wall between the transmitter and the

temperature station. Observe to see if the Temperature remains on consistently for

1-hour.

•If the temperature remains on while in the house then it is likely a

distance/resistance issue. Move the transmitter to different locations outside to find

a location where the temperature reading will hold.

•Distance/Resistance can cause loss of transmitter signal.

•Check Batteries.

Outdoor Temperature Is Stuck or HHH or LLL

•The last outdoor reading may remain (not change) for several hours when

connection is lost.

•The outdoor temperature reading will flash when the connection is first lost or

intermittent between the temperature station and the outdoor transmitter.

•Check batteries. Overpowered or underpowered batteries can cause this reading.

•Replace outdoor transmitter.

HI/LO Temperature readings

From normal display, press and release the button to view HI then LO Temperature

records since midnight.

Reset HI | LO Readings:

•Press the button to view records

•Hold the button for five seconds to reset all records at one time.

•HI | LO readings will reset to current temperature.

Note: The unit will automatically reset daily temperature record on the 12:00AM

Temperature Trend Arrows

The temperature trend indicators will update every 15 minutes or less. These trends

represent temperature changes over the past three hours. Example: At 12:00 the

arrows will reflect the trend since 9:00. At 12:30 the arrows will indicate the trend

since 9:30.

•UP ARROW: Temperature rising more than 1°C/ 2°F in the past three hours

•DOWN ARROW: Temperature falling more than 1°C/ 2°F in the past three hours

Sensor Search

1. Hold the button to search for outdoor sensor.

2. Reception Icon will flash while searching and be solid when sensor signal is

received.

IF the signal is lost, the RX will display the LAST DATA recorded for 10 minutes, after that

10 mins if the signal does not come back then display dashes "--". After 30 minutes start

looking for the RF signal automatically.

Outdoor Transmitter Fell and No Longer Works

•If there is no physical damage to the outdoor transmitter, the fall may not have

caused internal damage.

•An outdoor transmitter that has fallen into a puddle or other standing water or snow

may have water damage.

•Transmitters are water resistant, not waterproof.

•A fall can shock the transmitter or the batteries in the transmitter.

•Batteries that have fallen on a hard surface may be damaged and unable to function

properly.

•Complete a restart with fresh batteries.

•Use batteries dated at least six years in advance of the current year.

Outdoor Transmitter Drains Batteries Quickly

•Test a new set of alkaline batteries. Write down the date of installation and the

voltage of the batteries.

•When the batteries fail, please note the date and voltage again. This is helpful in

determining the problem.

•Check the distance and resistance between the transmitter and temperature station.

Transmitters at the end of the range may work while batteries are fresh but not

after they drain a bit.

•Check for leaking batteries, which may damage the transmitter.

Mounting/Positioning Outdoor Transmitter

•Mount outdoor temperature transmitters vertically and under a bit of an overhang.

•Protect the outdoor transmitter from standing rain or snow, and from the overhead

sun, which can cause it to read incorrectly. Generally, mounting under an eave or

deck rail works well.

•Construct a small roof or box for the transmitter if you do not have an overhang.

Please be sure the box is vented.

•Mount the transmitter on the North side to prevent sun from causing incorrect

readings.

•Mount at least 6 feet in the air for a strong signal.

•Outdoor transmitters are water resistant but not waterproof.

•Avoid more than one wall between the transmitter and the Temperature station.

•Do not mount near electrical wires, transmitting antennas or other items that will

interfere with the signal.

•RF (radio frequency) signals do not travel well through moisture or dirt.

•Place the outdoor transmitter and the Temperature station in the desired shaded

locations and wait approximately 1-hour before permanently mounting the

transmitter to ensure that there is proper reception.

•Do not mount the transmitter on a metal fence. This significantly reduces the

effective range.

La Crosse Technology, Ltd. Page 6

MOUNT

•Choose a location for the transmitter that is within range of the temperature station

and under an overhang for accuracy.

•Install one mounting screw into a wall leaving approximately ½ inch (12.7mm)

extended.

•Place the transmitter onto the screw, using the hanging hole on the backside.

•Gently pull the transmitter down to lock the screw into place.

Note: Always ensure that the transmitter locks onto the screw before releasing.

Distance/Resistance/Interference

Distance:

•The maximum transmitting range in open air is over 330-feet (100 meters)

between the outdoor transmitter and the temperature station.

•Consider what is in the signal path between the temperature station and the

transmitter.

•Consider the distance the temperature station is located away from other electronic

in the home.

Resistance:

•Obstacles such as walls, windows, stucco, concrete, and large metal objects can

reduce the range.

•When considering the distance between the transmitter and the temperature station

(330 feet open air) cut that distance in half for each wall, window, tree, bush, or

other obstruction in the signal path.

•Closer is better.

•Do not mount the transmitter on a metal fence. This significantly reduces the

effective range.

Interference:

•Consider items in the signal path between the transmitter and the temperature

station.

•Sometime a simple relocation of the transmitter or the temperature station will

correct the interference issue.

•Windows can reflect the radio signal.

•Metal will absorb the RF (radio frequency) signal.

•Stucco is held to the wall by a metal mesh.

•Transmitting antennas (ham radio, emergency dispatch center, airports, military

base etc.)

•Electrical wires (utilities, cable etc.)

•Vegetation is full of moisture and reduces signal.

•Dirt: Trying to receive a signal through a hill is difficult.
