Changing the transmission channel is only necessary when you are going to add additional
wireless outdoor sensor. See “ How to add extra sensors “ on Page 10.
How to set up
Insert batteries
1. Insert 2x AA batteries into the wireless sensor. Pay attention to the correct polarity. While
the sensor is transmitting, the red LED indicator will flash.
2. Open the battery compartment of the weather station and insert 3xAAA batteries in the
correct polarity. Close the battery compartment.
(Note: The screen will turn off after 10s and you will need to touch the button to
activate it.)
Setting the weather symbol
When the weather station is insert batteries on the first time, it will enter the weather
symbol setting. You can follow below steps.
1.You will see the weather symbol starts flashing, and the default is half sunny. It will
automatically adjust to the correct symbol. However, if you want to shorten the reception
time of the weather station, you can manually adjust it through INDEX button.
2.Press the MEM or CH button to save the setting.

Pairing the outdoor sensor with the weather station
Once the weather station is installed batteries), it will start receiving the pairing RF signals
from the outdoor sensor with the same channel for 3 minutes. You can touch the CH button
on the base unit to match the correct outdoor sensor.
Generally, the outdoor sensor will connect with the base unit automatically. If it doesn’t
connect, please follow below steps to set:
• Ensure that the weather station is in the same channels with the outdoor sensor.
• Long press the CH button on the base unit to search signal from the outdoor sensor.
• The sensor receiving icon will flash when searching for the signal.
• After the sensor is connected, the icon will become stable.
• Your weather station will search for the signal each 3 minutes every hour automatically
until it is connected.
Note: After replacing the sensor battery, you need to press and hold the CH button of the
station to receive again.
Mold indicator, dew-point display and heat index
Press the INDEX button to display the data.
First time press: Mold indicator
Second time press: Dew-point display
Third time press: Heat index
Mold indicator
The mold indicator ("MOLD" on the display) consists of temperature and humidity.
The indicator shows the possibility of mold growth.
Possible indicators:
Dew-point display
The dew point (“DEW” appears on the display) is the temperature below which dew or mist
forms from damp air.
Information:
-If the dew point is below 32°F, "LL.L" will appear on the display.
-If the dew point is higher than 140°F, “HH.H” will appear on the display.
Heat index
The heat index (“HEAT” on the display) consists of temperature and humidity, and displays
the perceived temperature.
- When the outdoor temperature is below 80°F, displays “ current actual temperature ”.
- When the outdoor temperature is over 80°F, the value will be calculated by software.
- When the outdoor temperature is over 158°F, displays “ 158°F ”.

Daily MAX/MIN data
All MAX / MIN temperature/humidity records will reset automatically at 12:00 (midnight).
From normal display, press and release the MEM button to view:
• MAX-- indoor and outdoor temperature/ humidity records.
• MIN-- indoor and outdoor temperature/ humidity records.
You can display the measured minimum and maximum values of the current day by pressing
the MEM button repeatedly in succession in the normal time display mode. Only the
maximum values appear, then the minimum values and the current values again.
Note: Press the MEM button to delete the highest and lowest temperature and humidity
values since midnight.
Other functions
Low battery indicator
If the batteries run too low to power the weather station, the outdoor sensor and signal
transmission, the battery level indicator 11 or 15 will appear on the display. Replace the
batteries in all devices as soon as possible. Restart the weather station.
Weather trend
For the temperature and humidity values measured by the wireless sensor, the trend is
displayed by an arrow:
Trend rising constant falling
Temperature
Humidity
Weather forecast icons
• The forecast icons are determined by your station's barometric pressure reading. Please
allow 7-10 days for calibration.
• 7 forecast icons use changing atmospheric pressure to predict weather conditions for the
next 12-hours.
• When Outdoor temperature is below 30.2°F and the forecast shows RAIN or T-STORM, the
station will display SNOW.
Currently displayed symbol means the forecast for the next 12 hours. It may not reflect the
current state of the weather.
The accuracy of the weather forecast is around 75 %.

10
Temperature alarm - If the wireless sensor measures a temperature between 33.8 °F and
30.2°F, there is a risk of frost and a snowflake symbol will flash. If the temperature falls
below 30.2°F for an extended period of time, the snowflake symbol will be constantly
displayed.
Note: Even if the temperature alarm is not displayed, when the temperature is around
freezing point, there is generally always a risk of frost and/or black ice. The outdoor sensor
can only measure the local temperature in the place where it is installed.
How to add extra sensors
The weather station comes with one wireless sensor. However, you can operate the
weather station with up to three wireless sensors. Additional wireless sensors are available
in our Amazon online shop.
Note:
1. You need to set different channels for the sensor (1-3). You can set it through pull the
stick on near the batteries.
2. Under the corresponding channel displayed on the base unit, press and hold the CH
button until the signal icon starts to flash to receive the signal from the newly added sensor.
Where the sensor should be placed
1. Sensor can be hung/placed.
2. Better place it under the porch and eaves.
3. The maximum range of the sensor can reach 328ft in an open area.
4. Make sure that the sensor is vertical so that moisture can be drained correctly.

Note：
•Shielding building materials such as reinforced concrete reduce or prevent the radio
reception between the base station and wireless sensor.
•Devices such as televisions, cordless phones, computers and fluorescent tubes can also
interfere with the wireless reception.
•Do not place the base unit and wireless sensors directly on the floor. This restricts the
range.
•In low temperatures in winter the battery performance of the wireless sensors can be
significantly reduced. This reduces the transmitter range.
Where the weather station should be placed
•Pull out the stand and place on a flat surface.
•Or use the hanging holes on the back to mount on a wall.
•Choose a location 6 feet or more away from electronics such as cordless phones, gaming
systems, televisions, microwaves, routers, etc.
•Place within range of the outdoor sensors (330 ft, 100m open air).
•Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce
the range.
Resetting the weather station
If the base station appears to display incorrect values, you should reset the weather station
to the factory settings.
a. Take the batteries out of the outdoor sensor and weather station.
b. Put batteries back in the outdoor sensor and weather station.
c. Put them together within a couple feet for about 20 minutes for a strong connection.
Care and maintenance
•Do not mix old and new batteries.
•Do not mix Alkaline, Standard, Lithium, or Rechargeable Batteries.
•Always purchase the correct size and grade of battery most suitable for intended use.
•Replace all batteries of a set at the same time.
•Clean the battery contacts and also those of the device prior to battery installation.
•Ensure the batteries are installed with correct polarity (+ and -).
•Remove batteries from equipment when it is not used for an extended period of time.
•Promptly remove expired batteries.
