7. 문제 해결
If you encounter issues with the adapter, consider the following:
- 장치에 전원이 공급되지 않음:
- Ensure both ends of the adapter are fully and securely connected.
- Verify that the power supply is functioning correctly and providing power.
- Check if the device itself is operational and not faulty.
- Confirm that the power supply's output (5.5mm x 2.5mm) and the device's input (5.5mm x 2.1mm) are correctly matched to the adapter.
- 느슨한 연결:
- If the connection feels loose, ensure the barrel sizes are precisely 5.5mm x 2.5mm for the male plug and 5.5mm x 2.1mm for the female jack. Slight variations in manufacturing can sometimes cause a loose fit.
- Avoid using the adapter if connections are excessively loose, as this can lead to intermittent power or damage.
