How to set up

Insert batteries

1. Insert 2 x 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 3 x AAA 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.)

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 press 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.

Setting the air pressure at the location

Long press the WEATHER button to set the air pressure manually.
You will see the air pressure unit starts to flash. Now you can set the air pressure through UP or DOWN button. You can follow below steps.

1. The air pressure unit starts flashing, the default is inHg, you can use the UP or DOWN button to switch the inHg/Hpa system.
2. Press the WEATHER button to confirm and enter the air pressure value setting.
3. The air pressure value starts flashing. The default is 29.88 inHg which is the air pressure of sea level. You can adjust it manually according to the data from the local meteorological station, the air pressure range of our weather stations is 8.85~34.43 inHg. You can also keep the default data unchanged to make it adapt automatically.
4. Press the WEATHER button to confirm and enter the weather symbol setting.
5. The weather symbol starts flashing, 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 UP or DOWN button.
6. Press the WEATHER button to save the setting and exit the air pressure mode.
7. To re-adjust, long press the WEATHER button till the air pressure unit start to flash.

Setting the Time, Date, etc.

Daily MAX/MIN data

All MAX / MIN temperature/humidity records will reset automatically at 12:00 (midnight).
From normal display, press and release the UP 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 UP 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 UP button to delete the highest and lowest temperature andhumidity values since midnight.

Other functions

Low battery indicator
If the batteries run too low to power the weather station, the battery level indicator will appear on the display, it will affect the outdoor sensor and signal transmission.
Replace the batteries in all devices as soon as possible. Restart the weather station.
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 -1°C (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 %.

Temperature alarm – If the wireless sensor measures a temperature between 1°C (33.8°F) and -1°C (30.2°F), there is a risk of frost and a snowflake symbol will flash. If the temperature falls below -1°C (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.
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 reach100m (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 (328 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.

Troubleshooting

Outdoor temperature is showing dashes
Replace battery| Dashes is generally an indication of wireless interference.
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.
Display screen not working| Check the battery polarity or battery level.
Accuracy of temperature and humidity| 1.When unpacking for the first time, the weather station and sensor are sealed for a long time, and it takes 1-2 hours to balance with the current ambient temperature.
2.Keep away from heat.
3.When comparing with other thermometers, it should be placed in the same position and allowed to stand for 1-2 hours. This is very important.
Inaccurate temperature or humidity| To ensure accurate temperature measurement, place units out of direct sunlight and away from any heat sources or vents.
