5. Setup

5.1. Battery Installation

Main Unit:

1. Open the battery compartment cover on the back of the main unit.
2. Insert 2 x AAA batteries, observing the correct polarity (+/-).
3. Close the battery compartment cover.

Outdoor Sensor:

1. Open the battery compartment cover on the back of the outdoor sensor.
2. Insert 2 x AA batteries, observing the correct polarity (+/-).
3. Close the battery compartment cover.

Note: It is recommended to insert batteries into the outdoor sensor first, then the main unit, to ensure proper synchronization.

5.2. Sensor Pairing and Placement

Once batteries are installed, the main unit will automatically search for the outdoor sensor. This process may take a few minutes. Ensure the sensor is within range (up to 30 meters in open air) and not obstructed by large metal objects or thick walls.

Outdoor Sensor Placement:

• Choose a shaded, dry location to avoid direct sunlight and rain, which can affect temperature readings.
• Ensure good air circulation around the sensor.
• Mount the sensor vertically, away from heat sources or vents.

5.3. Initial Time Synchronization

The weather station will attempt to synchronize its clock with the DCF (Germany) or WWVB (USA) radio signal automatically. This process can take several hours, especially during initial setup. Place the main unit near a window for better reception. Once synchronized, a signal icon will appear on the display.

6. Operating Instructions
