5. Maintenance
5.1. Cleaning
- IBS-P01R Floating Sensor: The manufacturer recommends hand washing only. Use a soft cloth and mild soap with water to clean the exterior. Avoid abrasive cleaners or harsh chemicals.
- IBS-P01R Receiver & IBS-TH2 Sensor: Wipe the exterior with a soft, damp cloth. Do not immerse these units in water.
5.2. Battery Replacement
When the battery indicator on the receiver (for IBS-P01R) or in the app (for IBS-TH2) shows low power, replace the batteries promptly. Refer to the setup section for battery type and insertion instructions.
5.3. Storage
If the devices will not be used for an extended period, remove the batteries to prevent leakage and store the units in a cool, dry place away from direct sunlight.
6. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| No temperature reading on IBS-P01R receiver. | Batteries low or dead; sensor/receiver out of range; pairing issue. | Replace batteries in both units. Move receiver closer to the sensor. Power cycle both units to re-establish connection. |
| IBS-TH2 not connecting to app. | Bluetooth off on phone; sensor batteries low; sensor out of range; app issue. | Ensure phone's Bluetooth is enabled. Replace sensor batteries. Move phone closer to sensor. Restart the app or phone. Re-pair the device in the app. |
| Inaccurate temperature readings. | Improper sensor placement; need for calibration (IBS-TH2). | Ensure sensors are placed correctly and not exposed to direct heat/cold sources. For IBS-TH2, use the app's calibration feature if necessary. |
| Short wireless/Bluetooth range. | Obstructions (walls, metal); interference from other devices. | Reduce obstructions between units. Move units away from other electronic devices that may cause interference. |
