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. |
