5. Setup
5.1. Battery Installation
Main Unit:
- Open the battery compartment cover located on the back of the main unit.
- Insert 3 x 1.5V AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
Wireless Outdoor Sensor:
- Open the battery compartment cover on the back of the sensor.
- Insert 2 x 1.5V AAA batteries, observing the correct polarity (+/-).
- Close the battery compartment cover securely.
5.2. Sensor Placement
Place the wireless outdoor sensor in a sheltered location outdoors. It should be protected from direct sunlight, rain, and other extreme weather conditions to ensure accurate temperature and humidity readings. The maximum transmission range between the sensor and the main unit is approximately 30 meters in open air. Avoid placing it near large metal objects or electronic devices that could interfere with the signal.
5.3. Initial Synchronization
After battery installation in both units, the main unit will automatically attempt to synchronize with the outdoor sensor and receive the radio-controlled time signal. This process may take a few minutes. Ensure both units are within range during this initial setup. If synchronization fails, try relocating the units or re-inserting the batteries in both the main unit and the sensor.
6. Operating Instructions
6.1. Display Overview
The large, backlit display provides comprehensive information at a glance:
- Time: Displays in 12-hour or 24-hour format.
- Date, Month, Day: Shows the current date and day of the week.
- Moon Phase: Indicates the current lunar phase.
- Indoor Temperature & Humidity: Current readings for the main unit's location.
- Outdoor Temperature & Humidity: Current readings from the wireless sensor.
- Weather Forecast Icons: Graphical representation of predicted weather conditions (e.g., sunny, cloudy, rainy).
- Comfort Index Icons: Visual indicators of indoor comfort levels based on temperature and humidity.
6.2. Setting Time and Date
The SWS 51 B features a radio-controlled clock for automatic time synchronization. If the signal is weak or unavailable, you can manually set the time and date:
- Press and hold the MODE or SET button (refer to your unit's specific button labels) to enter time setting mode.
- Use the UP or DOWN buttons to adjust the flashing value (e.g., hour, minute, year, month, day).
- Press MODE or SET again to confirm the setting and move to the next parameter.
- Exit setting mode by pressing MODE or SET repeatedly until the normal display resumes, or wait for automatic exit.
6.3. Alarm and Snooze Function
To set and use the alarm:
- Setting the Alarm: Press the ALARM button once to display the alarm time. Press and hold the ALARM button to enter alarm setting mode. Use the UP/DOWN buttons to adjust the hour and minute, pressing ALARM to confirm each setting.
- Activating/Deactivating Alarm: While the alarm time is displayed, press the ALARM button to toggle the alarm on or off. An alarm icon will appear on the display when activated.
- Snooze Function: When the alarm sounds, press the SNOOZE button (often labeled as LIGHT/SNOOZE) to temporarily silence it. The alarm will sound again after a few minutes. To stop the alarm completely, press any other button.
6.4. Max/Min Memory
The weather station records the maximum and minimum indoor/outdoor temperature and humidity values since the last reset:
- Press the MAX/MIN button once to display the maximum recorded values.
- Press the MAX/MIN button a second time to display the minimum recorded values.
- Press and hold the MAX/MIN button to clear the recorded maximum and minimum values.
6.5. Backlight
The display features a backlight for improved visibility in low light conditions. This is typically activated by pressing the LIGHT/SNOOZE button. The backlight will illuminate for a few seconds and then turn off automatically to conserve battery power.
7. Maintenance
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical agents, as these may damage the casing or display.
- If the device will not be used for an extended period, remove the batteries from both the main unit and the sensor to prevent potential leakage and damage.
- Ensure the outdoor sensor's battery compartment is securely closed to prevent moisture ingress, which can damage the electronics.
8. Troubleshooting
| Problem | Solution |
|---|---|
| No display on main unit | Check battery polarity and ensure batteries are fresh. Replace if necessary. |
| Outdoor temperature/humidity not displayed | Ensure the outdoor sensor has fresh batteries and is within range of the main unit. Re-synchronize if needed by removing and reinserting batteries in both units. |
| Incorrect time display | Verify the radio-controlled clock signal reception. If the signal is weak, try relocating the main unit. Manual time setting is also an option (refer to section 6.2). |
| Inaccurate readings | Ensure the sensor is placed in a sheltered area, away from direct heat sources or extreme cold. Allow time for readings to stabilize after setup. |
