2. Setup and Installation
2.1 Powering the Display Console
The display console can be powered by the included USB-C power adapter or by 2xAA batteries (not included). For continuous backlight operation, use the power adapter. Batteries provide backup power and allow for portable use, with the backlight turning off after 15 seconds to conserve energy.

2.2 Installing the 7-in-1 Outdoor Sensor
The outdoor sensor measures temperature, humidity, wind speed, wind direction, rainfall, UV index, and light intensity. Proper placement is crucial for accurate readings.
- Choose a Location: Select an open area free from obstructions (buildings, trees) that could interfere with wind or rain measurements. The sensor has a 100m transmission range to the console.
- Mounting Options: The sensor can be mounted on a pole or a flat surface. Ensure it is level for accurate rain gauge readings. If mounting on a pole, a minimum diameter of 2.4 cm (0.9 inches) is recommended.
- Battery Installation: Install 3xAA batteries (not included) into the outdoor sensor's battery compartment. Ensure correct polarity.
- Sensor Details: Under the battery cover, you will find a reset button, an LED indicator, and a manual transmit signal button.
