English • If the wires are pulled out of the terminal posts and the conductors come into contact with each other or surrounding devices, an excessive additional load may be placed on the amplifier. This may cause the amplifier to stop functioning, and may even cause it damage. • Be careful to observe the correct polarity of the connections between the cables and the speaker. If the polarity (+, -) of one of the speakers (left or right) is reversed the stereo image will be severely degraded. CAUTION These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts. D3-4-2-2-3_A_En 7 Where available, use the fixing bracket located on the back of the speaker system and attach a reinforced wire, such as stainless steel wire rope, to the studs or beams of the walls/ceiling. speaker system. Begin by setting the electric screwdriver to its minimum torque and gradually raise the torque until the screw starts to rotate. Check what torque setting you are on at this point (this will be the minimum torque required for the setup). After confirming the torque, return the rotating clamps toward the inside by reversing the direction of rotation of the screws. When doing this, take care that the screws do not come all the way out. Rotating clamp Speaker frame Screw • It is strongly recommended that you take double safe precautions to prevent the speaker from falling by accident. Stud/beam Reinforced wire (not supplied) 10 Attach the speaker frame to the wall/ceiling, and tighten the screws lightly (temporary attachment). At this point the rotating clamp will rotate so that the rotating clamp and frame are clamped on to the wall/ ceiling. Gently try pulling the speaker forward and check that all of the rotating clamps have rotated outwards and are lightly clamping to the wall/ceiling. 11 Tighten the screws firmly using no more than the maximum torque specified. Allowable maximum torque: 1.0 N⋅m Fixing bracket • Put the reinforced wire through the fixing bracket and attach to the studs or beams. Make sure the stud/ beam that you are attaching it to is strong enough to support the weight of the speaker system. 8 Place sound-absorbing material (such as fiberglass) around the speakers as necessary to improve sound quality. Use only sound-absorbing materials that comply with regional safety regulations. 9 Place the speaker into the hole you have cut. Make sure the rotating clamps are turned inward. • A Phillips screwdriver is required for loosening them. • When using electric screwdrivers, first find out the minimum torque required for the installation of the • Screwing them in too tightly could break the rotating clamps, twist the frames, damage the walls/ceilings and make it difficult to attach the grille. 12 Make sure that the screws are not crooked and that there is no gap between the wall/ceiling and frame. 13 Adjust the angle of the tweeter. (S-IC631-LR/S-IC831-LR only) Gently press the edge of the tweeter flange to adjust the angle of the tweeter as desired. Be careful not to touch the diaphragm while doing this. Make sure not to touch the diaphragm as it can be easily damaged. 5 En
