5. Setup
5.1 Battery Installation
The SENCOR SWS 3000 W Weather Station is battery-powered. Ensure you have the correct battery types as specified in the specifications section.
- Main Unit: Open the battery compartment cover on the back of the main unit (refer to Figure 4.4). Insert the required AAA batteries, observing the correct polarity (+/-). Close the cover securely.
- Wireless Sensor: Open the battery compartment cover on the back of the wireless sensor (refer to Figure 4.3). Insert the required batteries (typically AAA), observing the correct polarity (+/-). Close the cover securely.
5.2 Sensor Placement
Proper placement of the wireless sensor is crucial for accurate outdoor readings.
- Place the sensor in a shaded area to avoid direct sunlight, which can cause inaccurate temperature readings.
- Ensure the sensor is protected from direct rain or snow.
- Position the sensor within the effective transmission range (up to 30 meters in open air) of the main unit. Walls and other obstacles can reduce this range.
- Avoid placing the sensor near large metal objects or electrical appliances that may interfere with the wireless signal.

Figure 5.2: The main unit can be placed on a flat surface, while the sensor is mounted on a wall or suitable outdoor location.
5.3 Initial Power On and Pairing
After installing batteries in both units, the main unit will automatically search for the wireless sensor. This process may take a few minutes.
- Place the main unit and the sensor close to each other during the initial pairing process.
- Once connected, the outdoor temperature and humidity will appear on the main unit's display.
- If the connection is not established, remove and reinsert the batteries from both units, then try again.
6. Operating Instructions
6.1 Display Information
The LCD display provides various information at a glance:
- Outdoor Temperature & Humidity: Displayed prominently at the top.
- Indoor Temperature & Humidity: Displayed below the outdoor readings.
- Time & Date: Located at the bottom of the display.
- Weather Forecast Icon: An icon indicating predicted weather conditions (e.g., sunny, cloudy, rainy).
- Channel Indicator: Shows which sensor channel is currently displayed (if multiple sensors are used).
- Battery Indicator: Alerts when batteries are low for either unit.

6.2 Setting Time and Date
To set the time and date on your weather station:
- Press and hold the "AL/SET" button (usually located below the display) for a few seconds until the time digits start flashing.
- Use the "CH" or "MEM" buttons to adjust the flashing value (e.g., hour, minute).
- Press "AL/SET" again to confirm the setting and move to the next adjustable item (e.g., minute, year, month, day).
- Repeat until all settings are configured. Press "AL/SET" one last time to exit the setting mode.
6.3 Temperature Unit Selection (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F):
- Locate the °C/°F button, usually on the back or side of the main unit, or sometimes integrated with another button (e.g., "MEM" or "CH" with a short press).
- Press this button to toggle between the two temperature units. The display will update accordingly.
6.4 Channel Selection (for multiple sensors)
If you have multiple wireless sensors (up to 3 supported by SWS 3000 W), you can switch between their readings:
- Press the "CH" button (Channel) on the main unit.
- Each press will cycle through the available channels (CH1, CH2, CH3) or an auto-cycle mode.
- Ensure each sensor is set to a different channel using its internal switch (if available).
6.5 Memory Function (Min/Max Readings)
The weather station records the minimum and maximum temperature and humidity readings over a period.
- Press the "MEM" button (Memory) to view the maximum recorded values.
- Press "MEM" again to view the minimum recorded values.
- Press "MEM" a third time to return to current readings.
- To clear the recorded Min/Max values, press and hold the "MEM" button while viewing them.
7. Maintenance
- Cleaning: Wipe the main unit and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage. Store in a cool, dry place.
