					Before you begin   
					Thank you for purchasing the Bose® Lifestyle® 20 music system. This remarkably compact   
					system is a result of advanced technology developed by years of research. Technological   
					innovations that make the Lifestyle® 20 music system possible include the smallest CD   
					changer now available for home use and Jewel CubeTM speakers one-half the size of the   
					previous Acoustimass® cube speakers.   
					CAUTION:   
					Remove and dispose of the   
					three manufacturer’s shipping   
					screws from the bottom of the   
					Lifestyle® music center before   
					setting up your system.   
					To create speakers this small, the magnet inside is formed using the rare earth element   
					neodymium and has ten times more energy (per unit volume) than conventional magnets.   
					For high performance from such a small package, a port 3.8 inches (9.7 cm) long was   
					designed in the shape of a nautilus shell and enclosed inside the tiny cube.   
					The shipping screws are for   
					use by the manufacturer only.   
					They are not re-installable.   
					These, and numerous other innovations, bring you the Lifestyle® 20 music system, offering   
					superb sound, elegance, technology, and simplicity for music and home entertainment.   
					Your system includes:   
					• A Lifestyle® music center with built-in AM/FM radio and six-disc CD changer   
					• Powered Acoustimass speakers consisting of two Jewel Cube speakers   
					and a hide-away Acoustimass module   
					• An easy-to-use remote control   
					• Inputs for two video sound sources, an auxiliary source, and a tape deck   
					• Capability for operating two listening zones   
					Your Lifestyle® music system offers several ways to listen to superbly reproduced sound.   
					You can use its built-in sound sources, connect additional equipment such as a tape deck,   
					laserdisc player, VCR, or TV, and use two listening zones.

				Setting Up   
					® 
					Select the locations for your Lifestyle 20 music system   
					When you place your speakers according to the guidelines below, a combination of re-   
					flected and direct sound provides a good stereo image virtually everywhere in the room. You   
					may experiment with the placement and orientation of the Jewel CubeTM speakers and   
					Acoustimass® module to produce sound most pleasing to you.   
					To adjust your system for the characteristics of   
					your listening room, see “Fine-tuning your   
					system” on page 18.   
					Figure 2   
					Recommended speaker locations   
					Jewel Cube speakers   
					CAUTION:   
					Choose a stable and level   
					surface for your Jewel Cube   
					speakers. Vibration can cause   
					the speakers to move, particu-   
					larly on very smooth surfaces.   
					For stability, peel off the   
					backing from the rubber feet   
					and center them in the   
					1. For the most lifelike sound, place the Jewel   
					Cube speakers 6-12 feet (1.8-3.6 m) apart.   
					They can be as close as 3 feet (1 m) or as far   
					apart as 15 feet (4.6 m).   
					2. Place the Jewel Cube speakers 6-12 inches   
					(15-30 cm) from the surface behind them.   
					3. Direct one cube of each speaker toward the   
					center of the room (Figure 2). Direct the other   
					cube toward a side wall to create reflected   
					sound.   
					matching shapes on the   
					bottom of each speaker.   
					Note:The Jewel Cube speakers are magnetically shielded so you can place them close to   
					a TV without affecting picture quality.   
					Figure 3   
					Acoustimass module positions   
					Acoustimass module   
					Follow these guidelines to select a location for the Acoustimass module.   
					1. Place the Acoustimass module along a side wall near the front of the room, if possible   
					(Figure 2). You can place the module along the same wall as the speakers, if more   
					convenient.

					CAUTION:   
					Do not cover the ventilation   
					openings of the Acoustimass   
					module. The slots on the end   
					provide ventilation for the   
					built-in electronic circuitry, and   
					should not be blocked.   
					1. Place the music center on a level surface and allow enough room to lift the door.   
					2. Make sure it is close enough to any additional sound sources (TV, VCR, etc.) to allow for   
					cable length.   
					3. Keep the music center within 30 feet (9.1 m) of the Acoustimass module (the length of   
					the audio input cable).

					Fine-tuning your system   
					In most situations, following the speaker placement guidelines (see page 6) for your   
					Figure 24   
					Bass and treble controls   
					Lifestyle® 20 music system provides excellent sound quality.   
					You do not need to adjust tone settings for changes in volume, since Bose® patented signal   
					processing technology provides a natural tonal balance over the full range of volume   
					settings.   
					If desired, you can further fine-tune your system as described below.   
					Adjusting speaker controls   
					The Lifestyle® 20 music system TREBLE and BASS controls are located on the   
					Acoustimass® module (Figure 24). They allow you to adjust the treble (high frequencies) and   
					bass (low frequencies). In the normal setting, the dots on each control are in the 12 o’clock   
					position. You can also locate the normal setting by feeling when the control settles into the   
					notch at this position. Turn the controls clockwise to increase, and counterclockwise to   
					decrease, the amount of treble or bass.   
					® 
					Compensating for room acoustics

					le   
					The acoustics (sound qualities) of your room can affect the overall sound quality of any   
					speaker system. In general, you can reduce many problems with acoustics by the cautious   
					use of the TREBLE and BASS controls.

					s 
					Too much or too little treble   
					Rooms with too few sound-absorbing furnishings, especially those with bare floors and   
					walls, may sound overly shrill or “bright.” Turning down the treble control (toward –)   
					decreases treble sound.   
					Rooms with a lot of sound-absorbing furnishings, such as upholstered furniture, wall-to-wall   
					carpet, or heavy drapes, may reduce the treble sound of your system. Moving speakers   
					further away from soft furnishings increases treble. You can increase treble sound by slightly   
					turning up the treble control (toward +).   
					Too much or too little bass   
					You can decrease bass sound by turning down the bass control (toward –). To increase   
					bass, turn up the bass control (toward +).   
					Acoustimass module placement affects the amount of bass you hear. Placing the module   
					closer to the corner of the room will increase bass. Moving the module away from the   
					corner will decrease bass.

					Operating Your Lifestyle 20 Music System   
					Using two listening zones   
					The Lifestyle® 20 music system can direct sound from one or two sound sources to two   
					different listening areas at the same time. Each listening area, whether a room or a group of   
					rooms (including outdoor areas), is referred to as a zone. By adding powered speakers and   
					a second remote, you can establish two listening zones.   
					Figure 25   
					Example of two listening zones: the   
					Lifestyle® 20 speakers in zone 1   
					(living room) and powered speaker   
					system in zone 2 (bedroom)   
					How zones work   
					• 
					Zones 1 and 2 can play different sound sources at the same time – CD, AM/FM tuner,   
					TAPE, VIDEO sound, or AUX.   
					• 
					• 
					Both zones can listen to the same sound source at the same time.   
					Only one radio station can be played at a time.   
					Setting up two zones   
					The Lifestyle® 20 powered speakers are set up in zone 1.   
					Living   
					room   
					• 
					• 
					• 
					Any combination of rooms and floors in your home can be set up as zones.   
					Bedroom   
					Use a Lifestyle® 20 system cable to connect a second Bose® powered speaker system   
					to the SPEAKERS ZONE 2 jack on the back of the music center.   
					Zone 1   
					Zone 2   
					• 
					• 
					You can also use special adapters to connect an existing stereo system.   
					Use a second Lifestyle® system remote control to operate zone 2.   
					See your dealer or contact Bose for information on obtaining additional powered speakers,   
					remote controls, and adapters for connecting additional equipment.   
					Setting a second remote for zone 2   
					You need a second remote control, set to ZONE 2, to operate speakers connected to the   
					ZONE 2 output.   
					To set your second remote to control speakers in the second zone, follow these steps:   
					1. Open the remote control battery cover.   
					2. Locate miniature switch 8 (Figure 26). If it is set down for ZONE 1, slide it up for ZONE

					Maintaining Your Lifestyle 20 Music System   
					Changing the house code settings   
					Each Lifestyle® remote control uses a system of matching house codes to communicate   
					with its corresponding music center. If your remote’s commands ever conflict with those of   
					another nearby Lifestyle® system, you can easily set a new house code for your system and   
					its remote control(s) by following the procedures below.   
					1. Open the remote control battery cover and locate the miniature switches (Figure 27).   
					2. To create a new code, change the position of any of switches 1, 2, 3, or 4 by moving   
					them in the opposite direction from their current settings. Use a paper clip, ball point   
					pen, or similar object.   
					Note:Do not change switches 5, 6, or 7 at this time. The manufacturer’s standard setting is   
					switch 5 up and switches 6 and 7 down.   
					Figure 27   
					3. Replace the battery cover.

					4. Lift the music center door.   
					5. Turn both zones off.   
					6. Press and hold the STORE key. The display will begin to flash PROGRAM.   
					7. While you hold the STORE key and the display is flashing, press any key on the remote   
					control.   
					• The display stops flashing and momentarily shows PROGRAM to confirm recognition   
					of a new house code.   
					• The display verifies the house code by lighting four rectangles corresponding to the   
					Figure 28   
					Display confirming an example of   
					house code setting (switch 1 up,   
					switches 2, 3, and 4 down)   
					four switch positions (up or down). See the example in Figure 28.   
					8. Release the STORE key. The system remains off.   
					9. If you have additional remote controls, change the switches to match those of the first   
					remote control. It is not necessary to repeat steps 4-8.   
					Note:To verify your system’s house code, press STORE while the system is off. The display   
					confirms the settings of switches 1-4.

					Maintaining Your Lifestyle 20 Music System   
					Troubleshooting   
					Problem   
					What to do   
					System does not   
					function at all   
					• Make sure the power connector is plugged securely into the music   
					center, the power cord is plugged securely into the Acoustimass®   
					module, the power pack and power cord are plugged securely into   
					operating AC wall outlets, and the module power switch is on.   
					• Be sure to select a source (CD, AM/FM, etc.).   
					• Unplug the music center power pack for a minute, then reconnect it.   
					This allows the unit to reset itself after a power surge or power   
					interruption.   
					• If the system is not responding, press STORE, ERASE, and ON/OFF   
					(on the music center) at the same time, to reset the system.   
					No sound   
					• Make sure the audio input cable is firmly seated in the music center   
					SPEAKER ZONE 1 jack and the multi-pin connector on the other end   
					is firmly seated in the Acoustimass module AUDIO INPUT jack.   
					• Make sure the module power switch is in the ON position.   
					• Check the cables connecting the Jewel CubeTM speakers to the   
					Acoustimass module.   
					• Turn the music center off for ten seconds, then on again, to restore   
					communication between the music center and the speakers.   
					• Check the connections for any external components. Make sure to   
					select the correct source for the desired input.   
					• Be sure the CD is placed correctly, label-side up, in the magazine,   
					and the magazine is inserted properly in the music center.   
					• Increase the volume.   
					• Check to see if MUTE is lit on the display. If it is, press the MUTE   
					button on the remote control to unmute the sound.   
					• Disconnect any headphones.   
					• Connect the FM and AM antennas.   
					Remote control   
					is inconsistent   
					or does not work   
					• Check batteries and their polarity (+ and –). See page 10.   
					• Operate the remote control closer to the music center.   
					• Move the remote (or the music center) a few feet to avoid an area of   
					“dead spots.” See note on page 13.   
					• Make sure the remote control and music center house codes match.   
					Follow steps 4-8 on page 21 to match the house code settings.   
					Unit turns on   
					and off by itself,   
					or behaves erratically   
					• Change the house code setting to prevent signals from conflicting   
					with another nearby Lifestyle® system. See page 21 for instructions   
					on setting the house code.   
					Radio does not work • Make sure antennas are connected properly.   
					• Adjust antenna position to improve reception.   
					• AM antenna must be upright.   
					• You may be in an area of weak signal coverage.

					Problem   
					What to do   
					CD does not play   
					• Check to see if the play symbol   
					in the display is lit.   
					• After pressing the CD key, wait a few seconds before pressing PLAY.   
					• Make sure the magazine is properly inserted.   
					• Check to see if there is a disc in the magazine, label-side up. Display   
					shows a flashing box for a disc that is label-side down or cannot be   
					read.   
					• The disc may be defective. Try another disc.   
					• There may be dirt or dust on the CD. Clean the CD.   
					• Eject the magazine and try loading the CD again.   
					• A display message “E01” indicates a mechanical error. Unplug the   
					music center. Reconnect power and try again. If “E01” reappears,   
					call customer service.   
					FM sound is distorted • Adjust antenna position to reduce interference.   
					Sound is distorted   
					• Make sure speaker cables are not damaged and the connections   
					are secure.   
					• Reduce the output level from any external components connected   
					to the music center.   
					No tape, CD, VCR,   
					or TV sound   
					• Check the connections.   
					• Make sure the component is turned on.   
					• Refer to the component owner’s manual.   
					Transporting your music center   
					To transport your music center, follow these steps to lock down the CD mechanism.   
					1. Eject the CD magazine.   
					2. Make sure the music center is off (all zones).   
					3. On the music center, press STORE, ERASE, and PLAY/PAUSE at the same time. Then   
					release.   
					4. Press and hold the EJECT button for 10 seconds. The CD elevator moves into locked down   
					position.   
					5. If you hear the elevator continue to move up and down, wait 10 seconds and then repeat   
					steps 3 and 4.   
					The CD mechanism unlocks automatically the next time you select CD.

					Taking care of your Lifestyle 20 music system   
					The only maintenance needed is cleaning the system and your compact discs, and replac-   
					ing remote control batteries.   
					For information on replacing the remote control batteries see “Set up the remote control” on   
					page 10.   
					Handling CDs   
					Handle discs by their edges to prevent fingerprints and scratches (Figure 29).   
					Figure 29   
					Handling a CD   
					To remove stains or fingerprints from the surface of a disc, use a lint-free, soft, dry cloth.   
					Wipe in straight movements from the center of the disc to the outside (Figure 30). Do not   
					use any chemical products; they can damage the disc.   
					Do not write on, or attach labels to the surface of the disc.   
					To minimize exposure to dust and dirt, replace discs in their cases after use. Store each disc   
					in its case, out of direct sunlight, high temperatures, and humidity.   
					Cleaning the music center   
					Use only a soft, dry cloth to clean the outside of the Lifestyle® music center.   
					Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or   
					abrasives. Do not allow liquids to spill into any openings. Do not use any sprays near the   
					system.   
					Figure 30   
					Cleaning a CD   
					Cleaning the speakers   
					Clean the surface of your speakers with a soft, damp cloth. You can use an ammonia-free   
					window cleaner on a soft cloth to maintain the finish.   
					Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning   
					solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any   
					openings.   
					The speaker grille panels require no special care, although you may vacuum them carefully,   
					if necessary.
