TROUBLESHOOTING

If there is no sound from any of the speakers:

Check that receiver/ampli- fier is on and that a source is playing.

Review proper operation of your receiver/amplifier.

If there is no sound coming from one speaker:

Check the “Balance” control on your receiver/ amplifier.

Check all wires and con- nections between receiver/ amplifier and speakers.

Make sure no wires are touching other wires or terminals and creating a short circuit.

Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.

In Dolby® Digital or DTS® modes, make sure that the receiver/processor is config- ured so that the speaker in question is enabled.

Turn off all electronics and switch the speaker in ques- tion with one of the other speakers that is working cor- rectly. Turn everything back on, and determine whether the problem has followed the speakers, or has remained in the same channel. If the problem is in the same chan-

Declaration of Conformity

nel, the source of the prob- lem is most likely with your receiver or amplifier, and you should consult the owner’s manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www.jbl.com for further information.

If the system plays at low volumes but shuts off as volume is increased:

Check all wires and con- nections between receiver/ amplifier and speakers.

Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.

If more than one pair of main speakers is being used, check the minimum imped- ance requirements of your receiver/amplifier.

If there is no (or low) bass output:

Make sure the polarities

(+ and –) of the left and right “Speaker Inputs” are connected properly.

Consider adding a powered subwoofer to your system for use with digital “.1” surround formats.

If there is no sound from the surround speakers:

Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are con- nected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other.

Review proper operation of your receiver/amplifier and its surround sound features.

Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/amplifier has other surround modes you may use.

In Dolby Digital or DTS modes, make sure your receiver/processor is config- ured so that the surround speakers are enabled.

Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD player’s menu and the DVD’s menu.
