Main Unit (Receiver):

The main unit features a large color LCD display for all weather data, time, and settings. It has control buttons on the side and a backlight touch field on top. Power is supplied via a DC adapter or batteries.

Wireless Remote Sensor (Transmitter):

The remote sensor measures outdoor temperature and humidity and transmits data wirelessly to the main unit. It is battery-powered and includes a small display, a °C/°F button, a TX button, and a channel selector switch inside the battery compartment.

4. Setup

4.1 Powering On:

1. Remote Sensor: Open the battery compartment on the back of the wireless remote sensor. Insert 2 x AA batteries (not included), ensuring correct polarity. Close the compartment.
2. Main Unit: Insert 3 x AAA batteries (not included) into the main unit's battery compartment for backup power. For continuous display and adjustable backlight, connect the DC adapter to the "Power Supply Socket" on the back of the main unit and plug it into a power outlet.

4.2 Initial Synchronization:

Upon powering on, the main unit will automatically search for the remote sensor signal. Ensure the remote sensor is within range (up to 200ft/60m in open areas) and has fresh batteries. The outdoor temperature and humidity will appear on the main unit's display once synchronized.

4.3 Atomic Clock Synchronization:

The weather station will automatically search for the WWVB signal at 1:00 AM, 2:00 AM, and 3:00 AM daily, and after a reset, to synchronize the atomic clock. During this process, the screen may turn dark for approximately 7 minutes. If the screen does not stay on after searching, press the brightness adjustment button on the side of the host.

5.2 Setting Time and Date:

1. Press and hold the "SET" button to enter time setting mode.
2. Use "UP" or "DOWN" to adjust the flashing value (e.g., year, month, day, hour, minute).
3. Press "SET" to confirm and move to the next setting.
4. Repeat until all settings are complete.

5.3 Setting Alarm:

1. Press the "ALARM" button once to display the alarm time.
2. Press and hold the "ALARM" button to enter alarm setting mode.

5. Press "ALARM" again to activate/deactivate the alarm. An alarm icon will appear/disappear on the display.

5.4 Temperature Unit Selection:

Press the "DOWN" button to switch between Celsius (°C) and Fahrenheit (°F) for temperature display.

5.5 Backlight Adjustment:

When powered by the DC adapter, touch the "LIGHT/SNOOZE" field on top of the main unit to cycle through 4 brightness levels (100%, 75%, 50%, 25%, 10%, Off). When battery-powered, touching this field will illuminate the screen for 15 seconds to conserve power.

6. Weather Forecast Interpretation

The weather station forecasts weather changes for the next 12 hours based on barometric pressure trends. The display shows various icons representing different weather conditions:

Figure 6.1: Weather forecast icons and their corresponding conditions.

• Sunny: Clear skies.
• Slightly Cloudy: Partially cloudy.
• Cloudy: Overcast.
• Rainy: Light to moderate rain.
• Heavy Rainy: Significant rainfall or thunderstorms.
• Snowy: Snowfall.

Note: Weather forecasts are based on atmospheric pressure changes and may not always be 100% accurate for localized conditions.

7. Maintenance

7.1 Battery Replacement:

Replace batteries in both the main unit and remote sensor when the low battery indicator appears on the display. Use fresh batteries of the specified type (AA for sensor, AAA for main unit backup).

7.2 Cleaning:

Wipe the display and unit surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing.

7.3 Sensor Placement:

For optimal outdoor temperature and humidity readings, place the remote sensor in a shaded, dry location, protected from direct sunlight and precipitation. Ensure it is within the transmission range of the main unit.
