Then carefully consider your experience using the tools and taking the precautions referred to here.

You can describe the job and request a cost estimate before committing to installation service. [. . . ] Drill the hole inside the circle you have drawn. Choose a spot near the center or closer to the outside edge of the circle, depending on which will be easier when you begin to use your saw. Cutting the speaker hole Be sure to cut carefully to make the hole as regular as possible. However, when the speaker is in place, the frame overlaps the cutting edge by 5/8 in. (0. 6 cm), which masks minor cutting inaccuracies. Hold the cutting blade in a vertical position and keep it straight as you cut the hole. This helps prevent the blade from angling away from the outlined circle. Using the template 1. Center the template on the spot where you want the center of the speaker grille. Press the template to the ceiling with your hand or use painter's tape to hold it in place. CAUTION: DO NOT trace around or cut around the tabs that are for use only when the template serves as a paint shield. 8 5/8 " (21. 9 cm) 6 English TAB 2 TAB 3 TAB 4 TAB 5 TAB 6 TAB 7 TAB 8 INSTALLATION 2. Insert the tip of your saw into the pilot hole and cut most of the way around the circular outline. Connecting the speaker As you connect the wires, be careful to match the polarity of each wire to the proper terminal, as described below. An error here will adversely affect speaker performance. · If the screw does not seat properly, use the next highest torque setting to finish securing the screw. Or use a Phillips-head screwdriver to finish this manually. Tighten one of the four clamp screws until you can feel the frame press firmly against the ceiling. This indicates that the clamp is extended and is gripping the ceiling. Securing the speaker As you lift the speaker, keep the speaker cable above and out of the way to prevent pinching it. You may notice a security brace, located on the upper edge of the speaker, for use where local building codes require it. Use two hands to hold the edge of the speaker as you guide it into the ceiling hole. CAUTION: Be sure not to press on the two small drivers seated on the face of the speaker. Security brace Arrow One of four clamp screws Clamp CAUTION: Be careful not to damage or remove any of the foam gasket material along the edge of the speaker. This gasket is important to the operation of the speaker. Use the small arrow on the inside flange of each speaker to properly orient the speaker for your installation. Refer to "Placement guidelines" on page 4 to review guidelines for orienting the speakers relative to one another. CAUTION: Tighten these screws firmly, but avoid using so much pressure that the clamps compress the ceiling material. This can cause the material to crumble, creating an uneven surface with gaps between the speaker face and the ceiling. 8 English TAB 2 TAB 3 TAB 4 TAB 5 TAB 6 TAB 7 TAB 8 INSTALLATION 4. [. . . ] · Trace the cord from the speaker in question to the receiver/amplifier and make sure no wires from the + and ­ terminals on the receiver/amplifier are touching. · Disconnect the cord from the receiver/amplifier channel and reconnect it to a different receiver/amplifier channel. ­ If the performance is now fine, the problem lies in the original receiver/amplifier channel, the component source of the music, or the connections between the receiver/amplifier and the source. Check all of those to make sure they are performing properly. [. . . ]
