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
