4. Setup
Follow these steps to set up your weather station:
4.1 Powering the Main Unit
- Battery Installation (Optional): Open the battery compartment on the back of the main unit. Insert 2 x AA batteries, observing the correct polarity (+/-). This mode allows the screen to light up for 15 seconds when touched, then automatically turn off to save energy.
- DC Power Adapter (Recommended): For continuous backlight display, connect the provided DC power adapter to the DC Input Port (⑨) on the back of the main unit and plug it into a standard wall outlet.
4.2 Powering the Outdoor Sensor
- Open the battery compartment on the back of the outdoor sensor.
- Insert 2 x AAA batteries, observing the correct polarity (+/-).
- Close the battery compartment securely.

4.3 Sensor Pairing and Initial Calibration
- Once both units are powered, the main unit will automatically search for the outdoor sensor. Ensure the sensor is within range.
- The outdoor temperature and humidity readings should appear on the main unit's display. If not, press and hold the 'Channel' button (④) on the main unit to initiate a manual search.
- For accurate weather forecasting, the weather station requires an initial learning and calibration period of approximately 7 days. During this time, the device collects barometric pressure data to generate personalized forecasts for your location.
5. Operating Instructions
5.1 Display Functions
The large color display provides a comprehensive overview of various environmental data:
- Indoor/Outdoor Temperature & Humidity: Continuously displayed in large, easy-to-read digits.
- Weather Forecast: Icons representing sunny, partly cloudy, cloudy, rainy, heavy rain, and snowy conditions for the next 12 hours.
- Time & Date: Displays current time, day of the week, and date.
- Moon Phase: Shows the current phase of the moon.
- Comfort Indicator: Provides a visual indication of indoor comfort levels (HUMID, GOOD, DRY).

5.2 Setting Time and Date (DCF Function)
The weather station features a DCF (Atomic Clock) function for automatic time synchronization.
- Upon initial power-up, the station will attempt to synchronize with the DCF signal to set the correct time, date, and day of the week. This process typically occurs every morning.
- The DST (Daylight Saving Time) function ensures time accuracy during seasonal changes.
- If the DCF signal is weak in your location, you can disable this function and set the time manually. Refer to the detailed instructions in the full manual for manual time setting.
5.3 Adjusting Backlight
The backlight has four adjustable levels:
- When powered by DC Adapter: Press the 'Snooze/Light' button (③) to cycle through Bright → Normal → Turn Off → Bright (Loop). The backlight remains on continuously.
- When powered by Batteries: Touch the top of the unit to activate the backlight. It will cycle through Bright → Normal Bright (Loop) and automatically turn off after 15 seconds to conserve battery life.
5.4 Alarm Settings
To set the alarm:
- Press the 'Alarm' button (⑦) to enter alarm setting mode.
- Use the 'Up' (⑤) and 'Down' (①) buttons to adjust the hour and minute.
- Press 'Alarm' again to confirm and exit.
- To activate/deactivate the alarm, press the 'Alarm' button briefly outside of setting mode.
5.5 Temperature Unit Conversion (℃/℉)
To switch between Celsius (℃) and Fahrenheit (℉):
- Locate the ℃/℉ button, usually on the back or side of the main unit.
- Press it once to toggle the temperature display unit.
6. Placement and Range
Proper placement of both the main unit and the outdoor sensor is crucial for accurate readings and reliable wireless communication.
6.1 Main Unit Placement
The main unit can be placed on a desktop or mounted on a wall, making it suitable for various scenarios:
- Living room, bedroom, kitchen, office, etc.
- Ensure it is placed away from direct sunlight or heat sources that could affect indoor temperature readings.
6.2 Outdoor Sensor Placement
The outdoor sensor has a transmission range of up to 200FT/60M in an open space and supports up to 3 remote sensors for monitoring multiple locations.
- Place the outdoor sensor in a shaded area, away from direct sunlight and precipitation, to ensure accurate temperature and humidity readings.
- Avoid placing it near large metal objects, electrical appliances, or thick walls that could interfere with the wireless signal.
- While the sensor is designed for outdoor use, protecting it from direct heavy rain or snow (e.g., by placing it under an overhang or in a protective enclosure like a plastic jar) can extend its lifespan.

7. Maintenance
To ensure the longevity and accuracy of your weather station, follow these maintenance guidelines:
- Battery Replacement: Replace batteries in both the main unit and the outdoor sensor when the low battery indicator appears on the display. Always replace all batteries at the same time with new ones of the same type.
- Cleaning: Wipe the main unit and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the plastic components or display.
- Sensor Protection: Although designed for outdoor use, extreme weather conditions (heavy rain, snow, direct prolonged sunlight) can affect the outdoor sensor. Consider placing it under a protective cover or in a sheltered location to extend its lifespan.
- Storage: If storing the weather station for an extended period, remove all batteries to prevent leakage.
8. Troubleshooting
If you encounter issues with your VOKSUN Weather Station, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit | Low or no batteries; Power adapter not connected/faulty. | Replace batteries; Ensure power adapter is securely connected and functional. |
| Outdoor reading not displayed or inaccurate | Sensor out of range; Low sensor batteries; Interference; Sensor not paired. | Move sensor closer; Replace sensor batteries; Relocate sensor away from interference; Re-pair sensor (see Setup section). |
| Weather forecast inaccurate | Still in learning phase; Local atmospheric pressure changes. | Allow 7 days for initial calibration; Forecasts are based on barometric pressure trends, not real-time conditions. |
| Cannot change temperature unit (℃/℉) | Incorrect button pressed or button not responding. | Ensure you are pressing the dedicated ℃/℉ button, usually a small button on the back or side of the unit. |
| DCF time synchronization fails | Weak signal; Interference. | Relocate unit to an area with better signal reception (e.g., near a window); Disable DCF and set time manually if signal remains weak. |
