8. Maintenance
- Keep the charger clean and dry. Avoid exposure to moisture or extreme temperatures.
- Do not attempt to disassemble or modify the charger.
- Store the charger in a cool, dry place when not in use.
- Regularly check the USB cable for any signs of damage.
9. Troubleshooting
- Charger not working: Ensure the USB cable is securely connected to both the charger and a functional USB power source. Verify the power source provides at least 5V 2.2A.
- Batteries not charging: Check that batteries are inserted correctly with contacts aligned. Ensure batteries are compatible with the charger (Olympus BLH-1).
- Slow charging: Charging speed can vary depending on the power source. Using a higher amperage USB adapter (up to 2.2A) can improve charging time. Charging two batteries simultaneously may also result in a longer charge duration compared to charging a single battery.
- LED indicators not lighting up: This may indicate a power supply issue or a faulty connection. Recheck connections and try a different USB power source.
