User manual BOSE 301 II

[. . . ] Note: Because the grilles on the front of each speaker protect the drivers inside, we recommend that you do not remove them. CAUTION: 201 and 301 speakers are designed specifically for placement on a stationary shelf, table, or stand. On smooth surfaces like marble, glass or highly polished wood, vibrations may cause the speakers to slide. So be sure to attach the self-adhesive rubber feet to the bottom surface of each speaker for added stability and protection. [. . . ] The feet go in the corners of the flat surface, 1" back from the center of the curved front panel. To mount the speakers on a wall, use only the Bose WB-3 wall mounting bracket. Please follow the mounting instructions that come with these brackets. Here are some basic guidelines below: · Leave at least 24 inches (60 cm) from the speakers to any TV screens or monitors. · Keep the back of the speakers within 18 inches (45 cm) of the wall behind them. Figure 2 Placement guidelines 18" (45 cm) or more 12" (30 cm) or more LEFT speaker 4-12' (1-4 m) RIGHT speaker 18" (45 cm) or more CAUTION: For the most realistic sound image, make sure the left speaker is placed on the left and the right speaker is on the right side of your room, as you face them. 4 AM264981_01 _V. pdf · August 13, 2002 Setting Up Choose the cord It is important to use the proper gauge (thickness) of speaker cord. Wire recommendations Based on a maximum frequency response deviation of ± 0. 5 dB Gauge 18 (0. 82 mm2) 16 (1. 3 mm ) 14 (2. 1 mm2) 2 Length 20 ft (6 m) 30 ft (9 m) 50 ft (15 m) Note: Before running the speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. If necessary, contact an electrical installer for this information. Prepare the cord Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). At the ends of each cord, strip approximately 1/2 inch (12 mm) of insulation from both wires. Twist the bare end of each wire so loose strands will not touch across terminals. Also, do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. You may vacuum them carefully to remove dust. 7 AM264981_01 _V. pdf · August 13, 2002 Reference Troubleshooting Problem No sound What to do · · · · · · Make sure the receiver is plugged in and turned on.
