Troubleshooting Guide
What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the following table for possible problems.
PROBLEM | POSSIBLE CAUSE | SOLUTION | |
No sound. | • | Input (or output) cables are disconnected. | • Connect the input (or output) cables. |
(Blown fuse.) | • | Protection circuit may be activated. | • Check connections by referring to <Protection function>. |
| • Volume is too high. | • Replace the fuse and use lower volume. | |
| • The speaker cord is shorted. | • After check the speaker cord and fixing the cause of the short, | |
|
|
| replace the fuse. |
The output level is too small | • | The input sensitivity adjusting control is not set to the correct | • Adjust the control correctly referring to <Controls>. |
(or too large). |

|
| and wires well. |
| • A speaker wire is pinched by a screw in the car body. | • Connect the speaker wire again so that it is not pinched by | |
|
|
| anything. |
| • The switches may be set improperly. | • Set switches properly by referring to <Controls>. |
