3. Setup

3.1 Powering the Main Unit

The main unit can be powered by the included power adapter or by batteries (not included).

• Using Power Adapter: Connect the power adapter to the main unit and plug it into a wall outlet. The backlight will remain on and can be adjusted.
• Using Batteries: Insert the required batteries (refer to the battery compartment for type and polarity) into the main unit. The backlight will illuminate for 10 seconds after a button press to conserve power.

3.2 Installing Outdoor Sensors

Proper placement of the outdoor temperature/humidity sensor and rain gauge is crucial for accurate readings.

• Outdoor Temperature/Humidity Sensor: Place the sensor in a shaded area, away from direct sunlight and heat sources, to ensure accurate temperature readings. Ensure it is protected from direct rain and snow.
• Rain Gauge: Position the rain gauge in an open area, away from obstructions like trees or buildings, to ensure accurate rainfall collection. The self-emptying design requires no manual intervention for drainage.
• Ensure both outdoor sensors are within the wireless range of the main unit.

3.3 Initial Synchronization

After powering on the main unit and installing batteries in the outdoor sensors, the devices should automatically synchronize. If not, follow these steps:

1. Ensure batteries are correctly installed in all sensors.
2. Power on the main unit.
3. Press and hold the 'CHANNEL' or 'SEARCH' button on the main unit (refer to specific button labels on your device) to initiate a manual search for outdoor sensors.
4. The main unit will display outdoor readings once connected.

3.4 Time and Date Setting (WWVB Function)

The weather station is equipped with a WWVB receiver for automatic time and date synchronization with the atomic clock signal. This function typically activates automatically upon initial setup.

• Place the main unit near a window for better signal reception.
• The device will automatically calibrate daily for accurate time and date.
• If the WWVB signal is weak in your area, you can manually set the time and date using the designated buttons (e.g., 'MODE', 'SET', 'UP', 'DOWN'). Refer to the on-screen prompts for specific steps.
