BASIC SYSTEM CONNECTIONS Français Español English BASIC SYSTEM CONNECTIONS If your TV does not have a menu setting, follow the instruction (below) to use the on/off switch. If your TV has neither a switch nor a menu option for turning off the internal speakers, reduce the TV volume to its lowest setting. Using your TV speaker on/off switch: If the rear panel of your TV has a SPEAKER ON/OFF switch, set it to the OFF position and adjust the TV volume to about 80% of the maximum. Selecting the FIXED audio output option on your TV If you connected the media center to audio output jacks labeled FIX/VAR (or with no  indication if they are fixed or variable) follow these instructions. 1. Using your TV remote, display the audio menu on your TV screen.  In most cases this can be done by pressing the Menu button and selecting Audio. 2. Turn off the TV speakers (if you have not already done so) as described above. 3. Locate the Audio Output item and select Fixed. 4. Exit the audio menu on your TV screen. If your TV does not provide Fixed audio as an option, but you were able to turn off the internal speakers, set your TV volume to about 80% of the maximum. Your system is now ready for power Note: Bose recommends using a high-quality surge suppressor on all electronics equipment. Voltage variations and spikes can damage electronic components in any system. A quality suppressor can eliminate the vast majority of failures attributed to surges and may be purchased at electronics stores. Connect the two AC power (mains) cords in the following order: 1. On the connector panel of the Acoustimass® module, plug the appropriate end of the  Acoustimass module power cord into the AC power jack (Figure 17). 2.
