3.3 Adjusting Charging Parameters
To manually adjust charging parameters:
- 를 누르세요 C button to select the desired slot.
- 를 누르고 계세요 V button to enter manual setting mode.
- 사용하세요 C button to cycle through options (charging voltage, charging current).
- 사용하세요 V 선택한 값을 조정하려면 버튼을 클릭하세요.
- Confirm your selection by pressing and holding the V button, or wait for the setting to automatically apply after a few seconds of inactivity.

4. 유지관리 및 관리
- 충전기를 깨끗하고 건조하게 유지하세요. 부드럽고 마른 천으로 표면을 닦으세요.
- 충전기를 극한 온도, 직사광선 또는 높은 습도에 노출시키지 마십시오.
- 충전기를 분해하거나 개조하지 마십시오. 그렇게 하면 보증이 무효화되고 제품이 손상될 수 있습니다.
- 사용하지 않을 때에는 충전기를 서늘하고 건조한 곳에 보관하십시오.

5. 문제 해결
5.1 "EE EE" Error Message
If the display shows "EE EE", it indicates one of two conditions:
- Over-discharged IMR Battery: The battery is severely discharged. The UMS4 has an over-discharged battery activation feature that attempts to revive such batteries. If the error persists, the battery may be beyond recovery.
- 손상된 배터리: The charger has detected a damaged or faulty battery. Remove the battery immediately and dispose of it safely. Do not attempt to charge damaged batteries.

5.2 충전기 전원이 켜지지 않음
- USB-C 케이블이 충전기와 전원에 모두 단단히 연결되어 있는지 확인하세요.
- Try a different USB-C cable and/or power adapter to rule out faulty accessories.
- 전원이 정상적으로 작동하는지 확인하십시오.
5.3 배터리가 충전되지 않음
- Check battery polarity. Ensure batteries are inserted correctly.
- Clean the battery contacts and charger contacts with a dry cloth to remove any dirt or residue.
- Ensure the battery type is compatible with the UMS4 charger.
- If charging LiFePO4 or 3.8V Li-ion batteries, ensure manual mode selection for voltage is correctly set.
