4.2 Installing Batteries in the Outdoor Sensor

The wireless outdoor sensor requires batteries (not included, typically AA or AAA) for operation.

Open the battery compartment on the back of the outdoor sensor.
Insert the required batteries, observing the correct polarity (+/-).
Close the battery compartment securely.

4.3 Pairing the Outdoor Sensor

The main unit and outdoor sensor should automatically pair upon initial power-up. If the outdoor readings are not displayed, follow these steps:

Ensure both the main unit and the outdoor sensor are powered on and within range (typically up to 30 meters in open air).
Press and hold the "CHANNEL" or "SENSOR" button (refer to your unit's specific button layout) on the main unit to initiate a search for the outdoor sensor.
Press the "TX" button inside the battery compartment of the outdoor sensor to manually send a signal.
The outdoor temperature and humidity should appear on the main unit's display.

4.4 Initial Settings (Time, Date, Units)

After pairing, the unit will attempt to synchronize with the DCF77 radio signal for automatic time setting. If manual adjustment is needed or preferred:

Press and hold the "SET" or "MODE" button to enter time/date setting mode.
Use the "UP" and "DOWN" buttons to adjust values.
Press "SET" or "MODE" again to confirm and move to the next setting (e.g., hour, minute, year, month, day).
You can also typically switch between Celsius (°C) and Fahrenheit (°F) for temperature, and hPa/inHg for barometric pressure, using a dedicated button or within the settings menu.

5. Operation

5.1 Viewing Weather Data

Once set up, the main display unit continuously shows current indoor and outdoor temperature and humidity, barometric pressure, and a weather forecast icon.

5.2 Setting the Alarm

The weather station includes an alarm function.

Press the "ALARM" button to view the current alarm time.
Press and hold the "ALARM" button to enter alarm setting mode.
Use the "UP" and "DOWN" buttons to adjust the hour and minute.
Press "ALARM" again to confirm each setting.
To activate/deactivate the alarm, press the "ALARM" button briefly when not in setting mode. An alarm icon will appear/disappear on the display.

6.2 Weather Forecasts

Based on changes in barometric pressure, the weather station provides an icon-based forecast for the next 12-24 hours. These forecasts are estimations and may not always match official weather reports.

6.3 Radio-Controlled Clock (DCF77)

The integrated clock automatically synchronizes with the DCF77 radio signal, ensuring accurate time without manual adjustment, including automatic daylight saving time changes. The signal reception icon will indicate successful synchronization.

6.4 Moon Phases

7. Maintenance

7.1 Cleaning

Wipe the main unit and outdoor sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing. Ensure no moisture enters the device.

7.2 Battery Replacement (Outdoor Sensor)

When the battery indicator for the outdoor sensor appears on the main unit, replace the batteries in the outdoor sensor. Follow the steps in Section 4.2.

7.3 Placement Considerations

Main Unit: Place indoors, away from direct sunlight, heat sources, or drafts that could affect indoor temperature readings.
Outdoor Sensor: Place in a shaded, dry location outdoors, protected from direct rain and sunlight, to ensure accurate temperature and humidity readings. Avoid placing it near metal objects or large electrical appliances that could interfere with the wireless signal.

8. Troubleshooting

Problem	Possible Cause	Solution
No outdoor temperature/humidity reading	Sensor not paired, out of range, or low batteries.	Ensure sensor batteries are fresh and correctly inserted. Move sensor closer to the main unit. Re-pair the sensor (refer to Section 4.3).
Incorrect time displayed	DCF77 signal interference or poor reception.	Place the main unit away from electronic devices that may cause interference. Try repositioning the unit for better signal reception. Manually set the time (refer to Section 4.4).
Display is dim or unreadable	Backlight setting, power issue.	Press the backlight button to adjust brightness (refer to Section 5.3). Ensure the power adapter is securely connected.
Weather forecast seems inaccurate	Forecasts are based on barometric pressure trends and are estimations.	This is normal. The station provides a general trend, not a precise forecast. Ensure the main unit is not exposed to rapid temperature changes.
