To verify if your probe is charging correctly on the 4-in-1 Charger, please check the following:

1.Charging Indicator: A blue light will appear at the corresponding charger slot when the probe is charging. The light will turn off once the probe is fully charged, indicating it’s ready for at least 30 hours of use.
2.Probe Orientation: Ensure the probe is inserted correctly, with its tail making full contact with the metal plate in the charger’s slot.

If the issue persists, please try these steps:
1.Download the LightBlue app and check if “Probe” appears in the device list. Each charged probe should display as a separate entry. If no probe is detected, it may indicate a malfunction.
2.Record a short video showing the probe charging and send it to us. We’ll review it promptly and resolve the issue.
