4. Setup Guide
4.1 Powering the Main Unit and Sensor
The main unit supports two power methods, while the outdoor sensor requires batteries.
- Main Unit:
- Connect the DC5V power adapter to the main unit and a power outlet for continuous display.
- Alternatively, insert 2 x AA batteries (not included) into the battery compartment. The display will automatically turn off after approximately 15 seconds to save power when running on batteries.
- Outdoor Sensor:
- Insert 2 x AA batteries (not included) into the outdoor sensor's battery compartment.

4.2 Sensor Placement and Pairing
Place the outdoor sensor in a location that is protected from direct sunlight and rain, ensuring good ventilation. The wireless transmission range is up to 60 meters (200 feet) in open areas.
- Ensure both the main unit and the outdoor sensor have power.
- The main unit will automatically attempt to connect with the outdoor sensor. This may take a few minutes.
- If connection fails, press and hold the "CHANNEL" button on the main unit to initiate a manual search for the sensor. Ensure the sensor is within range.
- The weather station supports up to three external sensors. To add additional sensors, set each sensor to a different channel (CH1, CH2, CH3) before pairing.

Image: This image illustrates the weather station's capability to synchronize with up to three external sensors, allowing monitoring in different areas like a courtyard, bedroom, or basement.
4.3 DCF Time Synchronization
The weather station automatically synchronizes its time and date via DCF radio waves. After restarting, the DCF signal will automatically synchronize within 7 minutes.
- Ensure the weather station is placed in an area where it can receive the DCF signal.
- The clock will automatically adjust for daylight saving time (RCC function).
- You only need to select your time zone (-2 to +2), and the clock will handle the rest.
