| • Problem not diagnosed | •To diagnose the likely source of the |
|
| problem, it is often helpful to switch the |
|
| nonfunctioning speaker with one that |
|
| is functioning correctly. Turn off all |
|
| electronics before exchanging the |
|
| speakers. Turn everything back on, and |
|
| determine whether the problem is in |
|
| the same place, or has moved with the |
|
| speaker. If the problem is in the same |
|
| place, the source is most likely with your |
|
| receiver or amplifier. If the problem has |
|
| followed the speaker, then contact your |
|
| authorized JBL Synthesis custom installer |
|
| or dealer for further assistance. If that |
|
| is not possible, visit our Web site at |
