3.2 Placement of the Rain Collector
For accurate readings, proper placement of the rain collector is crucial.
- Choose an open area, away from trees, buildings, or other obstructions that could block rainfall.
- Ensure the collector is placed on a level surface to prevent inaccurate measurements. Use a spirit level if necessary.
- The collector should be easily accessible for occasional cleaning.

3.3 Placement of the Digital Display Unit
- Place the display unit indoors, within the wireless range of the rain collector.
- Avoid placing it near large metal objects, thick walls, or other electronic devices that could interfere with the wireless signal.
3.4 Initial Synchronization
Once batteries are installed in both units and they are placed appropriately, the display unit should automatically synchronize with the rain collector. This may take a few minutes. If synchronization does not occur, ensure both units are within range and try re-inserting batteries.

5. Maintenance
5.1 Self-Emptying Feature
The rain collector is designed to be self-emptying, meaning it does not require manual emptying after each rainfall event. Water is measured and then automatically drained from the unit.
5.2 Cleaning the Rain Collector
Periodically inspect the rain collector for debris such as leaves, twigs, or insects that may obstruct the funnel or tipping mechanism. Gently clean the interior and exterior with a soft, damp cloth. Avoid using abrasive cleaners.
5.3 Battery Replacement
Replace batteries in both the rain collector and the digital display unit when the low battery indicator appears on the display, or if the units cease to function. Use fresh, high-quality batteries of the specified type.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on indoor unit | Dead or incorrectly installed batteries. | Check battery polarity and replace with fresh batteries. |
| No rainfall data displayed | No wireless connection between collector and display; collector obstructed; collector batteries low. | Ensure units are within range. Clear any obstructions from the collector. Replace collector batteries. Re-synchronize units. |
| Inaccurate rainfall readings | Collector not level; debris in collector; calibration required. | Ensure collector is on a level surface. Clean collector of debris. Refer to advanced instructions for calibration adjustment if necessary. |
| Wireless signal loss | Distance too great; interference from other electronics or metal objects. | Move display unit closer to the collector. Relocate units away from sources of interference. |
