English Deutsch Français Italiano Nederlands STEPS TO INSTALLING Figure 21 Attaching wires to the terminals Make the speaker connections You need a Phillips-head screwdriver for this step. 7LSPay attention to maintaining the proper polarity (+ to + and - to -) with these connections. An error here will adversely affect speaker performance. Also be sure to tighten each screw securely, but not enough to cause undesirable compression of the wire. 1. If you have not done so earlier, loosen the screws on both terminals. 2. Insert the end of the marked wire (+) into the positive (+) terminal and tighten the screw (Figure 21). 3. Insert the end of the unmarked wire (-) into the negative (-) terminal. Tighten the screw. CAUTION: Do not allow exposed wires to brush against each other, which could damage your components. Trim excess wire and reinsert as necessary. + Test the speaker now With the connections still within reach, now is a good time to test the speaker to make sure it functions properly before you secure it in the wall. It may be preferable to begin installing the second speaker now, before you test either one. When you get the second speaker connected, you can test both speakers, and make sure they are both functioning fine before proceeding with the installation steps for each one. CAUTION: If you are testing the first speaker before the other one is connected, make sure the wire to that first speaker is the only one connected to the receiver/amplifier. This prevents unattached speaker wires from making contact, which can damage the receiver/amplifier. To test the speaker: 1. Turn on the receiver/amplifier and play a piece of music that is familiar to you. 2. Listen for clarity and accuracy of the performance from one speaker. • If you hear a problem, refer to "Troubleshooting" on page 27. • If the performance sounds fine, test the other speaker, or continue with the installation steps for this speaker. Position the speaker all the way into the hole 1. When the connections are completed, push any excess wire into the hole behind the speaker (Figure 22 on page 18). 17
