2. Case Troubleshooting

No.	Case	Inspection/Remedy
1	Trembling sound	Before replacing the speaker, inspect that the mounting screw is installed normally. After re-installing the speaker, verify that no trembling sound is heard. When hearing a trembling sound again, replace the speaker with new one.
2	Noise	Check if the wiring connector is connected normally. If not, reconnect the wiring connector. In case of radio static, check if there is a noise from CD. If a noise is heard with the radio and CD on, replace the speaker with new one. NOTE: In case there is only radio static, this may be the cause of the poor radio reception. Thus the speaker needs no repair and replacement.
3	Speaker in operative	Inspection of the wiring connection between the battery and the speaker Before replacing the speaker, inspect the wiring connection between the battery and the speaker is normal. Check the supply power to the speaker and the resistance, then inspect the sound quality. If the speaker works poorly, replace it with new one.

Dropping or rough handling of the speaker can cause damage.
