- Ensure the charger is connected to a power source.
- Carefully insert your compatible Sony Li-Ion battery into the designated battery slot on the charger. Ensure the battery is oriented correctly; it should slide in smoothly. For some batteries like the Sony NP-BX1, ensure it fits flush left in the slot with the green arrow facing up and in.
- The LCD display will illuminate and show the current charging status, typically indicating the battery's charge level.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on / LCD not displaying. | No power from outlet; charger not properly plugged in. | Ensure the charger is securely plugged into a live wall outlet. Test the outlet with another device. |
| Battery not charging. | Battery not inserted correctly; incompatible battery; faulty battery. | Re-insert the battery, ensuring correct orientation and a secure fit. Verify the battery is compatible with the TC-55S. Try charging a different, known-good battery. |
| USB device not charging. | USB cable faulty; device not compatible; charger overloaded. | Try a different USB cable. Ensure the USB device is compatible with standard USB charging. If charging a camera battery simultaneously, ensure the charger is not overloaded (though this charger is designed for simultaneous use). |
