Key Introduction

1. When the product is powered by Type-C DC 5V, the default backlight is always on, and the backlight can be manually turned off.
   When the product is powered by battery, the backlight will be automatically turned off after 10 seconds.

2. CH/SEARCH: Short press to switch the transmitter display, long press to search the transmitter signal.

3. MAX/MIN/CLEAR: Short press to toggle the display of the maximum and minimum values of temperature and humidity for the last 24 hours.
   Long press to clear the maximum and minimum values.

4. °Ff°C:Short press to switch the temperature display unit.
   Long press to switch the display unit of barometric pressure.

Temperature and Humidity Trends

1. indicates that the temperature & humidity is in an increasing trend. When the temperature change is higher than ±1°C and the humidity change is higher than ±5% in 1 hour, the arrow goes up.

2.  indicates that the temperature & humidity is steady.
   When the temperature change does not exceed ± 1C, humidity change does not exceed ± 5% in 1 hour, the arrow is parallel.

3. indicates that the temperature & humidity is in an decreasing trend. When the temperature change is lower than ±1C and the humidity change is lower than ±5% in 1 hour, the arrow is downward.

Outdoor Remote Sensor (Transmitter)

Note: To select the transmitter’s channel, you need to open the battery compartment.
Channel selection (1, 2, 3): Slide to set channel 1, 2 or 3.

Install Batteries

1. Receiver: Open the battery compartment and insert three “AAA” batteries with correct polarity.
2. Receiver: a. Connect the USB end of the charging cable (provided in the packaging) to the power supply port, and plug the other end into the Type-C jack located on the side of the receiver.

Low Battery Warning

If the battery of the remote sensor or the base unit is low, a low battery icon will display on the base unit.
If a low battery icon for the remote sensor appears, replace the battery.
If the low battery icon for the base unit, please plug in the power or replace the battery.

Barometer
The unit provides Relative Barometric Pressure.
When the barometric pressure change exceeds 2hpa in 1 hour, the barometric pressure change arrow indicates up or down, if the barometric pressure change does not exceed  ±2hpa in 1 hour, the arrow indicates parallel.
Long press the “F/C button on the front, you can choose the pressure unit as (in Hg) or (hpa).

Weather Forecast

The wireless thermometer can accurately forecast the weather for the next 24 hours.
The weather is divided into seven levels: sunny> partially sunny> cloudy> light rain> heavy rain> light snow> heavy snow.

Interpreting the weather forecast symbols

The weather station requires at least 3-7 days to acclimate to the local weather conditions. The weather station processes and analyzes weather patterns including temperature and barometric pressure changes for the past 24 hours in  order to determine the forecast, only then will the predicted weather forecast will reflect the actual weather for your immediate area. Until that time has elapsed, the predicted weather forecast may not accurately reflect the actual weather  to your immediate area.
The weather station will display the symbols to Indicate the  predicted weather forecast for the next 24 hours.
Note:
a. The weather forecasting is approximately 70% accurate. The accuracy rate might be lower in extreme weather conditions. The weather forecasting is for reference and for domestic use only. DO NOT rely on the weather station for any  serious matters such as health, business and financial decisions and/or agricultural planning and certainly not for life or death situations.
b. The weather forecast does not display the current weather. It displays the weather for the next 24 hours.

Place the Base unit and Remote Sensor

1. The receiver should always be placed in a well-ventilated indoor area and located away from vents, heating or cooling elements, direct sunlight, windows, doors, or any other openings.
2. The transmitter can be placed on a flat surface indoor or outdoor. Make sure the sensor is within the wireless distance from the receiver and with minimal obstructions.
   Although the remote sensor is designed to be rain-proof, it still must be always put in a dry area to avoid direct rainfall.
