Weather Forecast Icons
The forecast station predicts weather condition of the next 12 hours based on the change of atmospheric
pressure with 70-75% accuracy. As weather conditions cannot be 100% correctly forecasted we are not
responsible for any loss caused by an incorrect forecast.
INTELLIGENT WEATHER FORECAST
This station learns. Please allow 3 to 4 weeks for barometric calibration. This will ensure an accurate
personal forecast for your location.
The forecast station samples the barometric pressure every twelve minutes.
These samples are averaged hourly and daily then stored in nonvolatile memory.
The three hour pressure icon change is based off of the last four average hourly readings.
As the forecast station builds memory, it will compare the current average pressure to the past forty day
average pressure for increased accuracy. The longer the forecast station operates in one location, the
more accurate the forecast icons will be.

Model: T83653 www.lacrossetechnology.com/support Page | 8
RISING
STEADY
FALLING
Forecast Trend Arrows
In the upper right corner of the forecast display, you can see forecast trend arrows that indicate the rising
or falling pressure trend.
The up trending arrow indicates the weather is improving.
The down trending arrow indicates the weather may worsen.
When there is no arrow, the pressure is steady.
Temperature Trend Arrows
The temperature (2°F/1°C) and humidity (3% RH) trend indicators update every 30 minutes or less.
Example: At 1:00pm, the arrow indicates the change in temperature since 10:00am. At 1:30pm, the
arrow will indicate the temperature change since 10:30am.
Temperature has risen in the past 3 hours.
Humidity has risen in the past 3 hours.
Temperature has not changed in 3 hours.
Humidity has not changed in 3 hours.
Temperature has fallen in the past 3 hours.
Humidity has fallen in the past 3 hours
MIN/MAX Temperatures
The forecast station provides the daily minimum and maximum temperatures each day starting at
midnight (12:00 AM). The forecast station automatically resets the min/max temperatures at midnight
(12:00 AM).
View MIN data: Press and release the MIN TEMP button to view the minimum Indoor and Outdoor
Temperatures.
Reset MIN data: Hold the MIN TEMP button for five seconds and the Indoor and all Outdoor
Minimum Temperatures will be reset. The temperature area will show dashes briefly then return to
current temperatures.
View MAX data: Press and release the MAX TEMP button to view the maximum Indoor and Outdoor
Temperatures.
Reset MAX data: Hold the MAX TEMP button for five seconds and the Indoor and all Outdoor
Maximum Temperatures will be reset. The temperature area will show dashes briefly then return to
current temperatures.
Heat Index and Dew Point Temperature
Heat Index
Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot it feels to
a human being. As humidity increases, the body is unable to cool effectively; therefore, the temperature
will feel warmer.
View Heat Index: From a normal display, press the HEAT/DEW button once and Heat Index will show
instead of the outdoor ambient temperature.
Note: Heat index will be the same number as the temperature until the outdoor temperature is above 80
°F (26.7°C).

Model: T83653 www.lacrossetechnology.com/support Page | 9
Dew Point Temperature
Dew Point Temperature is the saturation point of the air, or the temperature to which the air has to cool in
order to create condensation. The higher the dew points, the higher the moisture content of the air at a
given temperature.
View Dew Point Temperature: From a normal display, press the HEAT/DEW button twice and Dew
Point will show instead of the outdoor ambient temperature. The words Dew Point will show near outdoor
temperatures.
Note: Dew Point is lower than the actual temperature.
Outdoor Temperature/Humidity Flashing
1. Low battery icon present in the outdoor temperature area:
Change batteries in the transmitter and press the TX button.
Hold the SENSOR SEARCH button for three seconds and the forecast station will search for the
outdoor transmitter again.
2. End of Transmission Range:
Move the transmitter closer to the forecast station.
Avoid obstructions in the signal path.
Keep transmitter and forecast station away from electronics.
Power the Forecast Station
AC Power Adapter
Insert enclosed 5-volt AC power adapter into a wall outlet, then into the forecast station.
Batteries:
1. Remove battery cover. Slide tab down and pull off to remove battery cover.

If the forecast station does not display indoor temperature after 60 seconds, remove adapter and
batteries and wait for at least 60 seconds before repeating the setup process.
Install Batteries in the Outdoor Transmitter
1. Slide the battery cover down, then lift off the back of the transmitter.
2. Insert two new AA batteries into the transmitter. Observe the correct polarity.
3. Keep transmitter 5-10 ft. from the forecast station during setup.
4. After 15 minutes, if the outdoor temperature shows on the forecast station, you can
move the outdoor transmitter outside to a shaded location within range of the
forecast station.
Outdoor Transmitter Signal Reception
After the batteries are inserted, the forecast station will search for the outdoor temperature/humidity
transmitter for three minutes.
The antenna symbol will flash during reception and temperature display will be dashes “---“.
The strength signal icon will animate until the sensor signal is received or for 3 minutes if no signal
available.
Search for Transmitter
If the outdoor temperature is not displayed after three minutes, hold the SENSOR SEARCH button on
the forecast station for three seconds to search for the outdoor transmitter.
Next, remove the battery cover from the transmitter then press the TX button to
send a signal.
If it still does not receive the outdoor temperature, remove the AC cord and
batteries from both the forecast station and the transmitter for 15 minutes repeat
setup instructions from step 1.
Position the Forecast Station
Choose a location for the forecast station that is within range of the outdoor transmitter. The
forecast station has a built in base stand to sit on a table or desk.
Choose a location 6 feet or more from electronics such as cordless phones, gaming systems,
televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.
Be aware of electrical wires and plumbing within a wall.
Best reception is achieved when the front or the back of the forecast station is facing the
outdoor transmitter. This allows a larger portion of the antenna to receive a signal.
Position the Outdoor Transmitter
Once the forecast station shows the outdoor temperature/humidity, place it and the transmitter in the
desired locations and wait approximately one-hour before permanently mounting the transmitter to ensure
that there is proper reception. The transmitter should be mounted vertically, in a shaded, protected area,
at least 6 feet from the ground to avoid damage and ensure accurate readings. The transmitter is water
resistant, not waterproof and should not be placed anywhere it will become submerged in water or subject
to standing water or snow. To achieve a true temperature/humidity reading, mount where direct sunlight

Model: T83653 www.lacrossetechnology.com/support Page | 11
cannot reach the outdoor transmitter. Mount the outdoor transmitter on a North-facing wall or in any well
shaded area. Under an eave or deck rail work well. The maximum transmitting range in open air is over
200 feet (60 meters). Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range. Place the transmitter at least six feet in the air to improve signal transmission.
Option 1:
Install one mounting screw (included) into a wall leaving approximately ½ of an 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.
Option 2:
Insert the mounting screw through the front of the transmitter and into the wall.
Tighten the screw to snug (do not over tighten).
