[. . . ] ® SURROUND CINEMA SPEAKERS SCS300. 7 OWNER'S GUIDE READ FIRST! Important Safety Precautions! CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: To reduce the risk of electric shock, do not remove cover (or back). CAUTION: To prevent electric shock, do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 1. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. [. . . ] Since different stands will have different weight capacities and stability characteristics, it is the customer's responsibility to check with the stand manufacturer or dealer whether that specific stand is capable of handling the weight and proportions of these loudspeakers in a safe and stable manner. JBL disclaims any liability for the selection of suitable floor stands and/or correct compat- ibility between the selected stand and these satellite loudspeakers. The floor stand adaptors are compatible with floor stands equipped with a 1/4"-20 threaded insert. Thread the two conductors through the two holes in the floor stand + ­ adaptor. Make sure to preserve the proper polarity (+ and ­ connections) by threading the positive conductor through the hole on the left, and the negative conductor through the hole on the right looking at the front of the adaptor. Push down on the red speaker terminal and insert the bare end of the positive wire into the hole under the red cap. Release the cap, and tug gently on the wire to make sure that the connection is snug. Follow the same procedure to connect the negative wire to its terminal. 5 Gently pull the slack out of the wire and screw the adaptor onto the back of the speaker in two places, as shown. Use the larger screw in the upper screw hole, and the smaller screw in the lower screw hole. Screw the floor stand adaptor into the floor stand's threaded insert until the speaker is firmly attached to the stand. If the bracket needs to be mounted in drywall, the customer is responsible for selecting and using appropriate wall-anchors and screws. Important Note: The Metal Nut ¡ must be fully tightened against the Satellite Speaker ¶ as described in Step 5 before beginning Step 7 in order to avoid damage to the Threaded Insert §. Step 7: Holding the Satellite Speaker ¶ with both hands, reinsert the ball portion of the Ball and Shaft £ into the Attachment Plate ¢. Step 8: Hand-tighten the Molded Nut TM while positioning the speaker for the desired orientation. If the Molded Nut TM is difficult to tighten by hand, insert the Metal Bar into one of the holes in the outer edge of the Molded Nut TM and use the bar as a lever. The swiveling ball enables you to aim the speaker to one side or the other, or to tilt it up or down. Stereo imaging may be improved by aiming the front speakers toward the listening position, especially for music selections. In Dolby Digital and DTS systems, it is best to aim all of the speakers (except the subwoofer) toward the lis- tening position at about earlevel height. In systems where only analog surround processing (such as Dolby Pro Logic) is available, it may be preferable to aim the speakers straight out from the wall to obtain a more diffuse sound. Step 9: Once the speaker's orientation has been finalized, insert the Metal Bar into one of the holes in the outer edge of the Molded Nut TM and tighten the Molded Nut TM securely. Keep the Metal Bar in a safe place in the event that you decide to adjust the speaker's orientation in the future. SPEAKER CONNECTIONS CONNECTION TIPS black to denote 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. [. . . ] Turn everything back on, and determine whether the problem has followed the speaker, or has remained in the same channel. If the problem 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 information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www. jbl. com. If there is no sound from the center speaker: · Check all wires and connections between receiver/ amplifier and speaker. [. . . ]
