2. Sensor Placement
Place the outdoor sensor in a shaded, dry location, protected from direct sunlight and rain. Ensure it is within the 60-meter transmission range of the main unit. Avoid placing it near large metal objects or electronic devices that may interfere with the wireless signal. The sensor is splash-proof (IP44) but not fully waterproof.
3. Initial Synchronization
After inserting batteries into both units, the main unit will automatically attempt to connect with the outdoor sensor and receive the DCF radio signal for time synchronization. This process may take several minutes. Ensure both units are close to each other during initial setup.

2. Time and Date Settings
The station automatically sets the time via the DCF radio signal. If the signal is not received or you wish to set it manually:
- Press and hold the "SET" button (or similar, refer to button layout on back) to enter time setting mode.
- Use the "+" and "-" buttons to adjust values.
- Press "SET" again to confirm and move to the next setting (e.g., 12/24 hour format, hour, minute, year, month, day).
3. Alarm Functions
The station supports up to two alarms.
- Press the "ALARM" button (or similar) to view alarm times.
- Press and hold "ALARM" to enter alarm setting mode.
- Use "+" and "-" to adjust the alarm time.
- Press "ALARM" to confirm and switch between Alarm 1 and Alarm 2 settings.
- To activate/deactivate an alarm, press the "ALARM" button repeatedly until the alarm icon appears/disappears.
- When an alarm sounds, press any button (except snooze) to stop it, or press the "SNOOZE" button for a temporary delay.
4. Temperature Unit Selection
To switch between Celsius (°C) and Fahrenheit (°F), press the "C/F" button (or similar, often combined with another button). This usually affects both indoor and outdoor temperature displays.
5. Adding Additional Sensors
The weather station can connect to up to two additional outdoor sensors (not included). To add a new sensor:
- Install batteries in the new sensor.
- On the main unit, press the "CH" (Channel) button to cycle through channels.
- Press and hold the "CH" button to initiate a search for new sensors. The main unit will display the new sensor's data once connected.
Maintenance
- Cleaning: Wipe the main unit and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both units when the low battery indicator appears on the display. Ensure correct polarity.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit | Dead batteries or incorrect polarity. No power adapter connected. | Replace batteries or check polarity. Connect DC power adapter. |
| Outdoor temperature/humidity not displayed | Sensor out of range, dead sensor batteries, or interference. | Move sensor closer to main unit. Replace sensor batteries. Re-synchronize sensor (see Setup). Avoid interference sources. |
| Incorrect time display | Weak DCF signal or manual setting required. | Move unit to a location with better signal reception. Manually set the time (see Operating Instructions). |
| Inaccurate outdoor temperature | Sensor exposed to direct sunlight or heat source. | Relocate the outdoor sensor to a shaded area, away from heat sources. |
