4. Mount the temperature transmitter outdoors in a shaded, well-ventilated area, protected from direct sunlight and rain, to ensure accurate temperature readings.
5. Ensure it is within the wireless transmission range of the base station.

3.4. Pairing Sensors with Base Station

Upon initial power-up, the base station will automatically search for signals from the rain gauge and temperature transmitters. This process may take a few minutes. Ensure all units are within range. If pairing does not occur automatically, refer to the troubleshooting section or the specific pairing instructions in the included manual (if different from this general guide).

4. Operating Instructions

4.1. Display Overview

The base station display typically shows the following information:

• Current Time and Date: Located at the top of the display.
• Indoor Temperature: Measured by the base station's internal sensor.
• Outdoor Temperature: Received from the external temperature transmitter.
• Rainfall Data: Displays current, historical, and cumulative rainfall amounts.
• Wireless Signal Indicators: Show connection status for transmitters.

4.2. Rainfall Monitoring

The device provides detailed rainfall information:

• ALARM: To set or activate the alarm function.
• HISTORY: To view past rainfall data.

5. Maintenance

• Cleaning the Rain Gauge: Periodically check the rain collector for leaves, debris, or insects that could obstruct the funnel and affect accuracy. Clean with a soft cloth and water. Do not use abrasive cleaners.
• Battery Replacement: Replace batteries in all units (base station, rain gauge, temperature transmitter) when the low battery indicator appears on the display. Use fresh, high-quality batteries.
• Sensor Placement: Regularly check that the rain gauge is level and unobstructed, and that the temperature transmitter is still in a shaded, well-ventilated spot.
• General Cleaning: Wipe the base station and transmitters with a soft, damp cloth as needed.

6. Troubleshooting

• No Display on Base Station:
  • Check if batteries are inserted correctly and are not depleted.
  • Replace with new batteries.
• No Outdoor Temperature/Rainfall Data:
  • Ensure batteries in the respective transmitters are fresh and correctly inserted.
  • Check the distance between the transmitters and the base station. They might be out of range.
  • Relocate units to minimize interference from other electronic devices or large metal objects.
  • Try re-pairing the sensors by removing and reinserting batteries in both the base station and transmitters, ensuring the base station is powered on first.
• Inaccurate Rainfall Readings:
  • Verify the rain gauge is mounted perfectly level.
  • Check the rain collector for any blockages (leaves, dirt, spiderwebs) and clean it.
  • Ensure no overhead obstructions are diverting or blocking rain from entering the collector.
• Inaccurate Temperature Readings:
  • For outdoor temperature, ensure the transmitter is in a shaded area, away from direct sunlight or heat sources.
  • For indoor temperature, ensure the base station is not near windows, vents, or appliances that emit heat/cold.
