The outdoor sensor transmits temperature and humidity data wirelessly to the main unit. It is powered by 2 x AAA batteries (not included).

5. Setup

5.1 Powering the Outdoor Sensor

1. Open the battery compartment cover on the back of the outdoor sensor.
2. Insert 2 x AAA batteries (not included), observing the correct polarity (+/-).
3. Close the battery compartment cover securely.

5.2 Powering the Main Unit

The main unit can be powered by either batteries or the included power adapter.

Using Batteries (Backup Power)

1. Open the battery compartment cover on the back of the main unit.
2. Insert 3 x AAA batteries (not included), observing the correct polarity (+/-).
3. Close the battery compartment cover securely.

Note: When powered by batteries only, the display backlight may be limited to conserve power.

Using the Power Adapter (Continuous Operation)

1. Connect the power adapter to the DC input port on the side of the main unit.
2. Plug the power adapter into a standard wall outlet.

Note: For continuous display backlight and full functionality, it is recommended to use the power adapter.

5.3 Initial Setup and Sensor Synchronization

Once both units are powered, the main unit will automatically search for the outdoor sensor and attempt to receive the radio-controlled time signal (RC). This process may take a few minutes.

• Place the outdoor sensor and main unit close to each other during initial setup.
• The outdoor temperature and humidity should appear on the main unit's display once synchronized.
• The clock will attempt to synchronize with the atomic clock signal. An antenna icon will indicate signal reception.

5.4 Placement of the Outdoor Sensor

For accurate readings, place the outdoor sensor in a sheltered location, away from direct sunlight and precipitation. Ensure it is within the wireless range of the main unit (typically up to 30 meters in open air, less with obstacles).

6. Operating Instructions

6.1 Display Overview

The large color display is divided into several sections:

• Top Left: Outdoor Temperature and Humidity.
• Top Center: Weather Forecast Icons and Barometric Pressure with Trend Graph.
• Top Right: Indoor Temperature and Humidity.
• Bottom Left: Time and Alarm Status.
• Bottom Center: Moon Phase Display.
• Bottom Right: Date and Day of the Week.

6.2 Setting Time and Date (Manual Adjustment)

While the unit attempts to set the time automatically via the radio-controlled signal, you can also set it manually if needed.

1. Press and hold the "SET" button (usually indicated by a gear icon) to enter time setting mode.
2. Use the "UP" and "DOWN" buttons (arrow icons) to adjust the flashing value.
3. Press "SET" again to confirm the setting and move to the next parameter (e.g., 12/24 hour format, hour, minute, year, month, day, language).
4. Exit setting mode by pressing "SET" repeatedly until the normal display resumes, or wait for automatic exit.

6.3 Temperature and Humidity Display

• The main unit displays both indoor and outdoor temperature and humidity.
• To switch between Celsius (°C) and Fahrenheit (°F), press the "°C/°F" button (if available, or check the "SET" menu).
• The unit automatically stores and displays minimum and maximum recorded temperatures and humidity. Press the "MEM" button to cycle through current, max, and min values.

6.4 Barometer and Pressure Trend

The weather station features a digital barometer displaying atmospheric pressure in hPa. A graph indicates the pressure trend over the last 12-24 hours, helping to predict weather changes.

6.5 Weather Forecast

The display shows weather forecast icons (e.g., sunny, cloudy, rainy) based on barometric pressure changes. This is a prediction and may not always be 100% accurate.

6.6 Moon Phase Display

The moon phase icon changes automatically based on the set date, providing a visual representation of the current lunar phase.

6.7 Alarm Functions

The weather station includes alarm functions. Refer to the specific icons on the display for Alarm 1 (AL1) and Alarm 2 (AL2).

1. Press the "ALARM" button (bell icon) to view alarm times.
2. Press and hold "ALARM" to enter alarm setting mode.
