Maintenance

Troubleshooting
Batteries Not Charging:
- Check Connections: Ensure the USB cable is securely connected to both the charger and the power source.
- Verify Power Source: Try a different USB power source (e.g., a different wall adapter, another USB port on a computer) to rule out issues with the power supply.
- Inspect Cable: The included USB cable may sometimes be faulty. Try using a different, known-good USB cable.
- Battery Insertion: Re-insert the batteries, ensuring they are seated correctly and contacts are clean.
Charger Runs Hot:
- It is normal for chargers to become slightly warm during operation. However, if the charger becomes excessively hot, disconnect it immediately.
- Ensure adequate ventilation around the charger during use.
- If overheating persists, discontinue use and contact support.
Batteries Not Reaching 100% Charge (as indicated by camera):
- After the charger's LED turns green, remove the batteries and re-insert them. The charger may show a red light again, indicating further charging. Repeat this process until the charger consistently shows green upon re-insertion.
- The camera's battery indicator may sometimes differ from the charger's. Rely on the camera's indicator for actual battery level during use.
