[. . . ] The power cord of the product should be unplugged from the outlet when left unused for long periods of time. If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the leadin wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system.

Never push objects of any kind into this product through openings, as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. Experiment with subwoofer placement by temporarily placing the subwoofer in the listening position and moving around the room until the bass reproduction is best. The brackets should be placed, if possible, so that the screws will fasten into a wooden wall stud. The customer is responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wall-mount the speakers. Slide speaker onto support. Place speaker and support on wall plate. 4 5 SPEAKER CONNECTIONS Connection Tips Separate and strip the ends of the speaker wire as shown. Speakers and electronics terminals have corresponding (+) and (­) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (­) terminal. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. When the "Auto/On" switch TM is switched to the "On" position, the subwoofer will remain on, whether or not program material is playing. If you will be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power switch ¡ to the Off position. Use RCA-type patch cords to connect the line-level subwoofer outputs on your receiver or amplifier to the line-level inputs on the subwoofer.

[. . . ] · If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/processor is configured so that the center speaker is enabled. If the system plays at low volumes but shuts off as volume is increased: · Check all wires and connections between receiver/ amplifier and speakers. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low (or no) bass output: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ­). [. . . ]
