EnglishUsing 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.
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.
•Any combination of rooms and floors in your home can be set up as zones.
•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.
•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
2, using a paper clip, ballpoint pen, or similar object.
3. Make sure the house code switches (1, 2, 3, and 4) match those on your first remote.
(See page 21 for more information on house codes.)
4. Replace the battery cover.

Operating Your Lifestyle® 20 Music System
Operating two listening zones
Controlling the zones from the remote controls
To control two zones you need to have remotes set to each zone. See instructions on
page 19 for setting a second remote to zone 2.
•You can select and control sources in each zone by commands from its remote control.
•You can control the volume in each zone directly from its remote control.
•You can turn each zone on and off directly from its remote control.
•You can listen to the same source in both zones.
Controlling the zones from the music center control panel
Turning two zones on and off from the music center involves a sequence of actions.
•To turn zone 2 on from the music center, press and hold the ON/OFF key.
Watch the display to see which zone is on or off. Release the key to keep the option
shown.
Holding the ON/OFF key causes this repeating sequence:
zone 1 zone 2
First ON OFF
Second ON ON
Third OFF ON
•To turn the zones on or off from the music center when both zones are on, press the
ON/OFF key for the following sequence:
zone 1 zone 2
ON ON
First press OFF ON
Second press OFF OFF
Third press ON OFF
Fourth press OFF OFF
Additional presses zone 1 repeats ON and OFF
•When zone 1 is on (even if zone 2 is also on), the music center keys control zone 1 only.
•When zone 2 is the only zone on, the music center keys control zone 2.
•If you press SOURCE SELECT for FM or AM while zone 2 is playing the other radio
band, the band selected in zone 2 flashes on the display. If you do not want to change
the band playing in zone 2, use SOURCE SELECT to choose another source within two
seconds.
The music center display of zone information
•When zone 1 or both zones are on, the display shows zone 1 information.
•When only zone 2 is on, the display shows zone 2 information.

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.
3. Replace the battery cover.

•The display verifies the house code by lighting four rectangles corresponding to the
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.

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).
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.
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.
