WALL-MOUNTING(Model E10 Only)

NOTICE: Important Safety Notes

•Proper selection of mount- ing hardware and installation of the wall brackets are the responsibility of the customer.

•This product is not intended for ceiling mounting.

Two Number 8 round head or pan head screws should be used per loudspeaker. The screw head should be between 5/16 inch (8mm) and 1/4 inch (6.3mm) in diameter, and the screw should be at least 2 inches (50mm) in length.

When installing screws in any wall, always use properly selected wall anchors. Attach two of the four self-adhesive rubber pads that came with the E10 loudspeaker to the

back of the enclosure in the two bottom corners so that the cabinet is spaced evenly from the wall. Select a suit- able mounting location on a wall. (The ceiling is not a suit- able mounting location.)

Drill two pilot holes, appropri- ately sized for the specific self-tapping screw or wall anchor that you will be using. The holes should be 8 inches (203mm) apart. See Figure 1. The holes should be 3/4" (19mm) below where you want the top of the enclosure to be positioned. Use a car- penter’s level to ensure that the holes are even and that the speaker will mount on the level.

Install the two screws into either a wooden wall stud or

anchor, and tighten them until the back of each screw head is about 1/8 inch (3mm) from the wall. See Figure 2. Install the loudspeaker by slowly moving the cabinet toward the screws so that the screw heads clear the larger circu- lar portion of the two key- holes. Once both screw heads have entered the key- holes, the loudspeaker should gently be lowered onto the screw shafts. Check that the loudspeaker is firmly locked onto the screws by gently pulling the speaker down and forward.

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 connec- tions between receiver/ampli- fier and speakers. Make sure no wires are touching other wires or terminals and creat- ing 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® mode, 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 question 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 prob-

lem is in the same channel, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner’s manual for that product for further infor- mation. If the problem has fol- lowed the speaker, consult your dealer for further assis- tance or, if that is not possi- ble, 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 connec- tions between receiver/ampli- fier 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 con- nected 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 connected. Make sure none of the speaker wires are frayed, cut or punctured.

•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/ampli- fier has other surround modes you may use.

•In Dolby Digital or DTS mode, make sure your receiver/pro- cessor is configured 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 disc’s menu.
