5. Maintenance
5.1. Cleaning
Regularly clean the display unit and outdoor sensors with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the surfaces. Ensure the rain gauge is free of leaves, debris, or insects to maintain accurate readings.
5.2. Battery Replacement
Replace the CR2032 backup battery in the main unit when the low battery indicator appears. For the outdoor sensors, replace their batteries (typically AA or AAA, refer to your specific sensor manual) as needed to ensure continuous data transmission. Always use fresh, high-quality batteries and ensure correct polarity.
5.3. Sensor Care
Periodically check the outdoor combined sensor for any obstructions to the wind cups or wind vane. Ensure the solar panel on the combined sensor is clean to allow for efficient charging. Clear any blockages from the rain gauge funnel.
